Which propylene pipes are best for heating. How to choose polypropylene pipes for a competent heating system. Selection criteria - what to look for

The repair of heating pipelines must be approached responsibly. The durability and correct functioning of the system depends on the quality of the materials and the strength of their installation. The market leaders in this area today are polypropylene materials, which are not inferior in strength to metal ones.

Polypropylene pipes began to be used for heating systems relatively recently. Before that, their place was occupied by solid steel pipes. Such structures were connected by welding, were strong, but difficult to install and expensive to manufacture.

Polypropylene pipes have undergone a number of important metamorphoses in their short history. By itself, polypropylene does not have the thermal stability expected by the companies developing it. That is why the first heat-conducting systems with such pipes quickly fell into disrepair, and the material itself began to be treated with skepticism.

At the moment, polypropylene pipes are significantly improved. There are various models that are used for the supply of cold and hot water, heat supply and sewerage. When carrying out repairs, it is important to choose pipes that are designed for specific purposes, otherwise the design will not be serviceable.

It is important! At the moment, there are many companies that produce and sell pipes for heating systems. It is advisable to buy pipes along with all components from official suppliers in specialized stores, since there are many low-quality fakes.

Varieties of PPR pipes

Polypropylene pipes are used in various fields, but not all are suitable for heating. In pursuit of cheap material, you can buy the wrong type of pipe that could withstand hot water under pressure. It is important to be able to distinguish one type of pipe from another.

The classification of polypropylene pipes is as follows:

• RR-N. This is the first generation of polypropylene pipes. This model has all the properties of the base material. PP-N are sealed and resistant to high pressure, in addition, they do not enter into chemical reactions. However, the melting of such a pipe can begin already at a temperature of 50 ͒С. Such pipes are used in the system of cold water supply, ventilation and for industrial purposes;
• RR-V. In the production of this type, the formula of the material was slightly changed. The pipes turned out to be stronger and more durable, but they still could not withstand temperature fluctuations. Such pipes have the advantages of the past generation and, in addition, better tolerate the effects of hot temperatures. However, they are unsuitable for heating systems and even hot water supply. Such pipes are often used in the construction of sewers;
• PP-R. In the production of these pipes, in addition to polypropylene, ethylene is used. This allows them to withstand high temperature loads. In addition, such pipes, as a rule, are reinforced, which allows them to withstand temperatures in excess of 100 ͒С. Reinforced PP-R pipes are the most suitable option for a heating system.

Polypropylene and polyethylene pipes are widely used in many construction areas. This material has proven itself in the implementation of heating systems, plumbing, sewerage. It is easy and pleasant to work with PVC products, their installation does not require special, expensive tools or fixtures. Before choosing pipes, you need to study their characteristics, dimensions and scope. For example, when conducting water supply, sewer samples should not be used, but it is better to buy special ones. For each case, elements with a certain marking are suitable, in which the exact information is encrypted.

Pipe marking

If you are going to carry out heating in a private house with your own hands, choose only pipes marked PPR!

Characteristics of PPR plastic

Pipes marked with the abbreviation PPRhave the following characteristics:

Types of polypropylene pipes

Solid plastic pipes are the cheapest

Monolithic products are made of solid PVC, the expansion coefficient is 0.15%. They can only be used in the installation of systems in which a substance with a low temperature moves, for example, for ventilation and cold supply.

At water temperatures above 10C °, the use of these pipes is simply impractical - they will not withstand and may crack or burst. This must be taken into account.

Reinforced polypropylene pipes

Aluminum is used to reinforce plastic products. The layers additionally reinforced with aluminium, can be located outside, in the form of a thin foil, or inside, in the form of dot perforations. Perforation is applied in the form of a grid with holes. During the casting of the product, the ductile material, getting into the holes, creates a tight adhesion of the polymer to the metal alloy.

Reinforced polypropylene pipes - the most reliable

Thanks to this type of strengthening, the system can withstand a coolant heated up to 90C °. It should be borne in mind that the installation and welding of aluminum-reinforced products can be complicated by the fact that they do not always correspond to the depth of entry into the fittings and require additional cleaning and removal of the top foil.

Fiberglass pipes

Such a product consists of two layers of plastic and a middle layer containing fiberglass. Glass-reinforced plastic elements do not require stripping and calibration during installation. Soldering is quick and easy, which significantly reduces time and cost.

Glass increases rigidity, density of elements and service life. The disadvantage of such pipes are the thermal elongation indicators, which are much higher than those of aluminum-reinforced products.

Operation of plastic pipes with fiberglass in different temperature conditions of the coolant

Metal-plastic pipes

Metal-plastic products are equipped with a top layer of PVC and an inner layer of aluminum. Such samples are able to withstand very high temperatures, can be used for heating, water supply of a private house. The disadvantage of metal-plastic elements is that the metal layer, being in contact with the transported substance, may be subject to corrosion.

Fitting

Fittings are parts for connecting elements in a pipeline. They are necessary for the arrangement of any engineering communications. Due to the fact that accessories of various models made of polypropylene with chrome-plated, brass inserts are on sale, it is easy to choose those that are most suitable for installing various plumbing fixtures. For installation, you will need a welding machine.

The size of the connecting parts is directly related to the dimensions of the heating pipes. Knowing the diameter of the main element, you will immediately understand which connecting part you need to buy.
Products come in several diameters:

Very often there is a situation when the diameter indicated on the package does not correspond to reality! It is best to buy fittings in stores, and not in construction markets - there is much less marriage there.

Types of connecting elements

There can be several connecting elements, in addition to fittings:

• Coupling- detail in the form of a ring. It is designed to fasten two pipes. The inner size of the coupling must match the outer size of the main part;
• Adapter- a fitting in the form of a barrel with a ring of smaller diameter. Adapters come with internal and external threads. Diameter transitions are simply necessary to connect the riser with horizontal heating pipes;
• corner. From the name it is clear that the element is bent at an angle. It is needed in order to form a corner joint between the pipes. Some craftsmen refuse corners and prefer to heat the plastic to 140C °, give it the desired bend. This can lead to a decrease in the capacity of the water supply and increase the possibility of leaks. Corners are produced with a bend of 45 or 90°. Threaded parts are very often used for mounting heated towel rails or radiators;
• Cross and tee. Very often it is necessary to mount several nodes of the system together. The cross connects the outlet of the four guides to the sides, respectively, three branches can be made on the tee. Both those and other parts can be without thread and with thread for different types of pipes;
• Contours. Often, during the heating process, there is a technological obstacle on the way that needs to be bypassed. In this case, contours are applied. They make it possible to change the trajectory of the pipe without violating its integrity;
• temperature compensators. It is a simple structure of flexible form, externally resembling a folded loop, performs the desired function. With a sharp increase in the temperature and pressure of water in the pipes, this important part compensates for the expansion within the pipeline system. The device is easily mounted in the structure, increases its durability without leakage.

Video

You can watch a short video on how to choose the right polypropylene pipes and fittings for them.

For each of us, the heating systems in the house, in the apartment, in most cases, are metal lines that entangle all heated rooms. Only quite recently, in new buildings, in private houses and in cottages, new consumables began to be used - polypropylene pipes for heating. mainly made of metal pipes, less often metal-plastic, while in private small house building, polypropylene is increasingly used for these purposes.

Heating pipes made of polypropylene, which have appeared quite recently, have already managed to prove high efficiency and reliability in practice. Thanks to the use of synthetic materials, it was possible to radically simplify the solution of the problem of arranging heating circuits in home heating systems. The technical characteristics of pipelines from consumables of this type are fully consistent with the technological parameters of modern heating equipment. The price and long-term uninterrupted operation brought polypropylene pipes to the first positions in the segment of thermal engineering and equipment.

What is the reason for such popularity of new consumables for heating circuits? What is the secret of high manufacturability of polypropylene pipelines?

Why polypropylene? What are the features of this material?

With the advent of polymers, the thermal industry has received a number of undeniable advantages. The technologies used today in production have made it possible to manufacture new consumables in large quantities. Due to the high manufacturability, it was possible to achieve a low cost of finished products. The polymer obtained as a result of physicochemical thermoplastic reactions has unique physical properties, is cheap and durable. have become one of the latest "know-how", which has successfully found its application in the field of heating technology.

High-quality polypropylene pipes from European manufacturers are ease of installation, strength and heat resistance. You can buy polypropylene pipes for heating on the website https://agpipe.ru.

Today, the use of such material is becoming fashionable. Bribes the technical characteristics and manufacturability of polypropylene. With the help of polypropylene products, consumable components and accessories, it is possible to equip almost any water heating system, both in terms of configuration complexity and length. With metal pipes, this will definitely not be possible to afford.

On a note: if we compare the cost of materials and installation of a metal pipeline for a heating system in a private house with similar works that use synthetic products, the latter win in price.

The main advantages are inherent in the material itself. Polypropylene, or as it is commonly called, is a thermoplastic, a substance that changes its plasticity as a result of changes in ambient temperature. At high temperatures, up to 140 0 C - polypropylene becomes soft and plastic, at a temperature already at 175 0 C, the thermoplastic begins to melt, losing its structure. Accordingly, at temperatures up to 120 0 C, the material is able to retain its basic physical characteristics and properties.

Knowing about such physical properties of polypropylene, the question involuntarily arises. Can the substance be used for the manufacture of pipelines for heating systems? For water heating, where boiler water can reach a maximum of 95 0 C, the use of such a material is an ideal option.

The only thing to pay attention to is the coefficient of thermal expansion. With prolonged contact with hot water circulating through the mains, polypropylene can change its usual shape. Therefore, always when choosing accessories for a heating system, look at the pipe markings. Each product is marked accordingly, i.e. data on the scope of the product are applied on the pipe.

On a note: for ordinary polypropylene pipes, the thermal elongation is 10 cm per 1 m. For reinforced, reinforced polypropylene pipes, this figure is much less, only 1 cm per 1 m.

Heating can be equipped only with the use of special polypropylene products, which are based on a reinforcing layer.

Polypropylene pipes for heating have the following advantages:

• multilayer structure ensures successful interaction with high temperatures;
• simple and easy installation, waste-free production;
• light weight;
• no need to paint the finished pipeline;
• environmental and technological safety;
• the presence of low hydraulic resistance;
• absence of blockages and salt deposits in pipelines;
• dielectric properties of the material;
• long periods of operation.

Do not forget that, unlike collet and socket joints on metal structures, polypropylene lines are connected together by diffusion welding. Connections, thus, turn out strong, steady and tight. You can use polypropylene pipes in any room for cold and hot water supply, for equipping warm water floors and radiator heating lines.

On a note: the use of these materials for central heating systems in regions with low temperatures is not recommended. The combination of low temperatures, reaching the boiling point of the coolant and high pressure can cause a rupture of the heating circuit made of polypropylene. When working with autonomous boilers, which provide for adjusting the heating temperature of the coolant, it is possible to use polypropylene pipes.

Reinforced polypropylene pipes - ideal for heating systems

Among the variety of polypropylene consumables, only some products can be used for heating systems. When asked which polypropylene pipes are best for heating, the answer is unequivocal. The best choice is reinforced polypropylene consumables.

Ordinary polypropylene pipes are not able to withstand high temperatures normally. Such a line will sag due to thermal elongation and lose its attractiveness. Such products, the smallest, are suitable for the installation of low-temperature heating systems. Warm water floors with such consumables will serve for a long time and reliably. Due to the fact that in these heating systems the heating temperature of the coolant is not high, thermal elongation does not play such a critical role. In addition, the water circuit is most often walled up in a concrete screed and is less susceptible to deformation.

The rest of the products manufactured and offered for sale have various applications, while the reinforced products are designed mainly for hot water systems and heating. The heating circuit for a single-circuit or double-circuit heating scheme will have the best performance in all respects if it is made of reinforced polypropylene. Its marking is PPR-AL-PPR or PPR-FB-PPR, where R means random copolymer, and AL and FB reinforcing components, aluminum or fiberglass. Therefore, when buying, you should pay attention to all the inscriptions, symbols and numbers that are printed on polypropylene pipes for heating.

The random copolymer has a high degree of crystallization, therefore, due to the inclusion of this compound in the polymer composition, polypropylene of high strength and stability is formed. It is this synthetic compound that is the base for the manufacture of water heating pipes. Additional reinforcement only improves the performance of consumables. It is easy to work with such pipes directly on the site, and the installation of a pipeline from PPR pipes does not require the use of special tools.

On a practical plane, we can say that polypropylene pipes are used almost everywhere where there is a need to ensure the supply of water or other liquids. However, multilayer products are intended for the heating circuit.

On a note: single-layer, homogeneous pipes with a nominal pressure of PN10 are used for low-temperature heating systems. Warm floors work great if the water circuits are laid using ordinary polypropylene loops. For underfloor heating, the maximum heating temperature of the coolant is 50 0 C, which is consistent with the technical parameters of conventional thermoplastic.

In all other cases, when a coolant with an elevated heating temperature is used, polybutene or are used. Layers in synthetic channels are either solid or perforated, i.e. in the form of a sieve, with round holes. All this is done with only one goal, to reduce the effect of high temperature on polypropylene, to reduce thermal expansion.

For example, by comparing the coefficients of thermal expansion of a conventional, homogeneous material and a pipe with an aluminum layer or fiberglass.

In the first case, the thermal expansion values ​​will be 0.15%, while for reinforced products these figures are only 0.03%. Between pipes reinforced with aluminum foil and fiberglass, the difference is small, only 5-6%. So, both are good consumables.

The only difference is that when installing the pipeline, aluminum-reinforced products must be cleaned. For these purposes, a shaver is used. Otherwise, a strong connection of individual pipe fragments cannot be achieved. The aluminum layer in the places of future soldering is removed to a depth of 1-2 mm.

What to look for when choosing consumables

Having an idea of ​​​​what polypropylene pipes for heating systems are, how to choose the right consumables, start preparing for installation. Heating in the house, the system is open or closed, therefore, in addition to the properties and quality of the material, pay attention to the permissible nominal pressure that pipelines can withstand. Pressure is designated PN, and numbers, for example, PN10, PN16, PN20 and PN25, indicate how many atmospheres the line can withstand.

The next aspect that you should always pay attention to is the thickness of the pipe walls and the diameter of the passage channel.

Important! on most products offered for sale, there is an outer diameter of the pipe. Do not confuse it with the size of the internal section of the product.

Let's consider in detail. What aspects should be paid attention to when buying consumables for the heating system.

The first aspect is working pressure. The marking indicates the maximum operating value at a temperature of 20 0 C. For water heating circuits, products marked with values ​​corresponding to 20 and 25 atmospheres are usually used. It is worth remembering here that polypropylene can withstand peak loads, however, as the temperature rises, the resistance of the material decreases.

The second aspect is the temperature of the working environment. The maximum allowable hot water temperature must be indicated on the pipe. Usually, specific numbers “75 0 C” or “90 0 C” are put on products. In addition to everything, there are color indicators and stripes on polypropylene pipes. Red stripe - the material is designed to transport hot water, blue stripe - cold water supply.

The third aspect is reinforcement. The abbreviation includes Latin letters indicating the composition of the reinforcing layer. You choose which pipe is better reinforced with aluminum or fiberglass. If you have doubts about the strength and reliability of the product, opt for a composite.

The fourth aspect is the diameter of the pipe. Here, one should rely on the data of thermal and hydrodynamic calculations. The fact is that for individual sections of the pipeline, the diameter of the pipes can be different (heating systems "warm water floors" use a pipe diameter of 16 mm). The calculations take into account the parameters of the operating pressure, coolant temperature, boiler power and the number of connection points. Typically, for a home heating system from a centralized main, consumables with a diameter of 25 mm are used. With autonomous heating, the diameter of the pipeline may vary depending on the technological need.

For reference: note! In no case can the inner section of the piping be larger than the diameter of the pipe in the riser. For pipe fragments with diameters of 20 and 26 mm are used.

Features of the installation of pipelines made of polypropylene

In order to make the correct installation of the heating main, it is necessary to have a ready-made working scheme at hand. It must necessarily take into account fragments of the pipeline, where polypropylene pipes are connected to metal-plastic products or come into contact with metal fragments. With the same outer diameter, the cross section of the polypropylene pipe will be smaller than that of a metal product or metal-plastic. The wall thickness of all three materials is different, hence the technical nuances that arise during docking.

It is important to ensure that in the end all used pipeline fragments have the same internal diameter.

Stages of assembling a polypropylene pipeline of a heating system

Having decided on the choice of a pipe for our own heating system, and these are probably PPR brand products with a reinforcing layer, we proceed to installation. The assembly of the heating circuit can be divided into several stages. Docking of cut pieces and fragments of pipes is carried out using diffuse soldering.

For work you will need:

• scissors or pipe cutter;
• shaver - a device for stripping;
• soldering iron.

To prevent marriage during soldering, practice connecting individual fragments. Otherwise, it is possible to assemble a pipeline in which the connections will not meet the requirements of operation. Fittings and couplings must be put on the pipe with some effort.

The build steps are as follows:

• cutting blanks according to the established dimensions;
• chamfering and calibration of reinforced products;
• heating and docking of fragments (soldering).

Each stage has its own difficulties and peculiarities. The scissors should make a smooth and even cut with a gap of 1 mm to the inside.

Important! A gap greater than 1 mm can cause the passage in the pipe to be blocked. The melted plastic will narrow the bore.

After cutting comes calibration, the process of chamfering cut fragments and pieces. As a result of a simple manipulation, the junction is made even, and with the help of a shaver, the aluminum layer is removed to the entire depth of the future junction. The soldering process itself determines the quality of the installation. Overheating can deform the joint and significantly narrow the through hole. The optimal heating temperature of the soldering iron, according to experts, is 260 0 C.

In order to work in an apartment, you can use an 800 W soldering iron. The heating time of a polypropylene pipe depends on its diameter:

For example, consumables with a diameter of 16 mm, heat up for no more than 5 s. Products with a diameter of 25 mm are heated for 7 s.

Plastic cools quickly, so you need to connect and center the fragments immediately after heating. Complete hardening occurs within the next 5 minutes. A properly docked pipeline is necessarily subjected to pressure testing, as a result of which miscalculations and design flaws are revealed.

conclusions

Polypropylene pipes used in home heating systems are a real step forward. Due to the low cost of the manufacturing process, it was possible to obtain a high-tech, qualitatively new material. Excellent technical characteristics and physical properties make it possible to use polypropylene in almost all water communications. For heating systems, today, the best and most justified option.

So, for the installation of a heating system, you decided to opt for polypropylene pipes. If you just go to the store without first “getting to know” them, you will be faced with the fact that they turn out to be different. The price, the outer color of the pipe and in the section: monophonic and with some circular color changes. Let's try to deal with these nuances. The first thing that will clearly catch your eye will be the outer color of the pipe: white, gray or some other.

This is precisely where there is no difference - this is a purely design decision and does not affect the quality of the pipe in any way. Choose according to your taste (or mood)).

Today we can confidently say that polypropylene pipes are confidently and quickly replacing traditional metal counterparts (from cast iron and steel) from literally all areas of water supply and sewerage. But the consumer sometimes faces a painful choice: how to buy the best polypropylene pipes? which company polypropylene pipes are best? Wanting to make this task easier, guided by the feedback from consumers and professionals (experienced installers), we compiled a kind of rating of polypropylene pipes and collected brief characteristics of popular brands in a single article.

What are the best pipes?

By the unanimous opinion of all construction forums, owners of apartments and houses where polypropylene pipes are installed, as well as the installers themselves, German products are recognized as the undisputed leader in quality from the widest variety. Moreover, it is worth noting that all pipe manufacturers from Germany deserve only laudatory reviews. And the choice of a particular brand is most often based only on its availability in a particular region.

German brands of polypropylene pipes and fittings:

The characteristics of each brand are given in a separate thematic article.

Polypropylene pipes made in the Czech Republic are considered to be a very worthy product in terms of quality.

In third place in terms of quality characteristics, users put cheaper pipes and fittings made in Turkey.

Polypropylene pipes from Turkey are in demand in Russia

An even more budget option is Chinese and Russian products. From China, you can pay attention to such generally good brands as Dyzain and BLUE OCEAN. Russia is represented on the market by PRO AQUA brands; RVC; Heisskraft; Santrade; Politek.

The next thing to know about polypropylene pipes is their property to increase in length when heated. So, an ordinary polypropylene pipe with an increase in temperature by 100º will become longer: +150 mm for every 10 meters. During operation, such an extension will be evident. And when heated, straight pipes will take on a wave-like shape. We learned to deal with this shortcoming. To reduce thermal expansion, polypropylene pipes are reinforced.

Reinforced pipes

There are several types of reinforcement for polypropylene tubular products.

Fiberglass

Fiberglass reinforced polypropylene pipes are the best option for heating. What are they? This is when there is a fiberglass layer inside the polypropylene layer. On a cross section of a pipe, it looks a bit like the annual rings of a cut tree. Inside a layer of polypropylene, then a layer of fiberglass and outside again a layer of polypropylene. When using fiberglass reinforcement, thermal expansion decreases tenfold and is +15 mm per 10 meters.

Also, polypropylene pipes are reinforced with aluminum. Basically, such reinforcement is external. When there is a layer of aluminum on top of polypropylene, which prevents thermal expansion. In addition to external reinforcement with aluminum, the following combination is also used: inside a thin layer of polyethylene - inside aluminum reinforcement - outside polypropylene. Moreover, the aluminum layer is not continuous, but with the letter C.

From the foregoing, it is clear that reinforced polypropylene pipes must be chosen for heating and hot water supply systems. Accordingly, unreinforced pipes from this material are used for cold water supply, where there are no large temperature drops.

A few words about installation. Installation of polypropylene pipes is very simple, but requires the use of special equipment: a socket welding machine and a set of special nozzles, special wire cutters or a pipe cutter (can be replaced with a metal saw), a shaver (for pipes with aluminum reinforcement) and a beveler. And if you have certain skills, you can independently cope with the installation of polypropylene pipes. The easiest to install is an unreinforced polypropylene pipe. The pipe, which is reinforced with fiberglass, is almost not inferior to it. Fiberglass melts on a par with polypropylene, and the result is a reliable connection. If there is an outer layer of aluminum, then it is completely cleaned off at the place where the pipe enters the fitting. With internal reinforcement - the matter is more complicated. You need a special tool that will clean out the inner layer of aluminum and trim the pipe.

Additional benefits of polypropylene

• Long service life. Manufacturers claim a service life of their products from 25 to 50 years. Of course, subject to the requirements for operation.
• Pipes have low thermal conductivity. Heat loss "wasted" is minimal.
• Very resistant to temperature changes. In the declared ranges, they do not lose their shape and structure.
• Possibility of self-assembly. Although a couple of practical lessons will not hurt.
• Polypropylene pipes do not conduct electricity. There will be no unpleasant "surprises" in the form of an electric shock.
• The throughput is 20% higher than that of metal pipes.
• Lightweight pipes. The weight of polypropylene pipes is nine times less than that of metal pipes.
• The material is very resistant to corrosion and inert to chemical reactions.
• Easy to operate and maintain.

The price range of polypropylene pipes for heating is very diverse. So, one meter of Ekoplastik polypropylene pipe will cost approximately 1.9 EUR/linear meter. For a meter of REHAU pipe, you will have to pay 4.5 EUR. The cost of pipes of Chinese origin fluctuates around 1 USD per 1 meter of length. So the choice of quality, specifications and prices is very diverse.

The main types of polypropylene pipes

To solve the problem of which polypropylene pipes to choose, information about what types they are will help.

Pipe products made of polypropylene are:

Single layer polypropylene products

They are produced in the following types:

1. Type 1 - PPH is produced from homopropylene. Such products are used for laying ventilation systems and industrial pipelines, in the arrangement of cold water supply.
2. Type 2 - PPB is made from polypropylene block copolymer. The scope of use is the creation of floor heating systems and cold water mains, the production of high-impact fittings.
3. Type 3 - PPR is made from polypropylene random copolymer. Scope - water supply and heating.
4. PPs pipes are a kind of flame retardant specialty polypropylene.

Multilayer reinforced pipes

To decide which reinforced polypropylene pipe is better, you need to know what

this type of pipe products allows:

1. Reduce thermal elongation of thermoplastic products.
2. Aluminum foil reinforced tubular products are smooth and perforated.

In addition, you should familiarize yourself with the types of pipes depending on the method of reinforcement:

1. On the outside there is a solid or perforated layer of aluminum foil.
2. The inner aluminum layer is located closer to the outer edge, and the perforated foil facilitates the connection of the layers without the use of glue.
3. Fiberglass is used.
4. The layer inside is made of a composite mixture, which includes polypropylene and glass or fiber. See also: "What are the types of polypropylene pipes, production materials and areas of use."

Overview of companies producing pipes from polypropylene

According to experts analyzing the pipe products market, the rating of polypropylene pipes looks like this:

1. The leading place belongs to the products of companies from Germany, including Pexay, Akwatherm, Banninger, Wefatherm.
2. In second place are Czech polypropylene pipes manufactured by ECOPLASTIC.
3. A little lower in the ranking are the products of Turkish companies Pilsa, FIRAT, TEBO, Valtek and Vesbo, Jakko.
4. The fourth place was taken by the pipes of companies from China - Blue Ocean and Dyzain.
5. Fifth place went to products manufactured in Russia.

Pipes of Russian production

Since the products are of good quality, many domestic buyers are interested in which company polypropylene pipes are better.

Russian pipe products PRO AQUA can withstand temperatures up to 95 degrees. It is not subject to corrosion, chemicals and serves for many years. Products of the RVC brand are reinforced with aluminum, so they are used in the arrangement of hot water supply and heating systems (read: “Characteristics of RVC polypropylene pipes, advantages, areas of use”).

Heisskraft pipes are also capable of satisfying consumer demand. Politek products are distinguished by an average level of quality - with the same wall thickness, they are deformed during compression. See also: "Production stages of polypropylene pipes, raw materials and technologies used."

Pipe products from China

As a rule, Chinese products are of low quality. The exception applies to Blue Ocean products manufactured by a UK subsidiary and Dyzain brand of polypropylene pipes.

Pipes from Turkish manufacturers

TEBO produces polypropylene pipes with a diameter of 20-160 millimeters for the creation of heating and water supply systems. Products perfectly resist the effects of chemically aggressive environments. For the arrangement of water supply structures, there is a separate product line - PN10 and PN20. To create heat supply systems, pipes are used that are reinforced with aluminum or fiberglass.

Also noteworthy are Turkish polypropylene pipes Pilsa, Novaplast, Vesbo, VALTEC and others, which are distinguished by a high degree of strength, wear resistance and elasticity.

Czech polypropylene products

A well-known brand of polypropylene pipes manufactured in the Czech Republic is WAWIN Ecoplastik products. It occupies one of the leading places in the world market, as it is distinguished by the highest quality that meets all standards.

These pipes are used for such purposes:

• ventilation wiring, water supply;
• creation of heat supply systems - central and laid under the floor;
• for the arrangement of high-pressure cold water supply systems and low-pressure mains for centralized heat supply.

Excellent characteristics are distinguished by pipes from the FV-Plast company, which have special aluminum inserts. Thanks to this, the products of this brand resist temperature changes. It is used for laying water supply lines, underfloor heating systems and supplying thermal energy. See also: "Production and use of acrylic pipes, characteristics."

STABI pipes with an aluminum insert are used for installation under the floor of pipelines for the movement of hot water.

German polypropylene pipes

Products from German manufacturing companies are deservedly considered the undisputed leader among high-quality pipe products.

For the installation of water supply and heating structures, Wefatherm pipes are used. Their advantages lie in the presence of a perfectly smooth inner surface, which makes it possible to maintain the initial pressure in the pipeline to the maximum. It is possible to combine different types of pipes, as the company produces a wide range of fittings.

The manufacturer Akwatherm is one of the leaders in the production of polymer products for underfloor heating systems, fire extinguishing, air conditioning, water and heat supply.

If you need to purchase reliable products for arranging heating structures or hot water supply lines under pressure up to 20 bar, experts advise paying attention to Faser German polypropylene pipes. They enter the distribution network in green with a diameter of 16-250 millimeters and white with a cross section of 20-40 millimeters.

Rehau pipes, which are used for internal and external laying of utilities in residential buildings and industrial facilities, do not need a recommendation. But for the installation of products of this company you need to have professional skills.

When choosing pipe products, you need to purchase products of the line that is suitable for laying a particular type of pipeline. For example, if you want to equip a system that supplies hot water, you should use pipes that are designed specifically for such lines and then there will be no serious problems during operation.

Range of polypropylene pipes

Everyone has probably heard about the victorious march of polypropylene in the field of plumbing. But which polypropylene pipes are better to use in a given situation? For example, when I first came to a specialized store specifically for this product, I was puzzled by the rather extensive number of offers. So I propose to deal with the most significant criteria, which, due to inexperience, can be considered insignificant trifles.

A few general features

Why is it even worth switching from the same metal to polypropylene? Why are plastic pipes better than cast iron or metal pipes? Before delving into their varieties, you need to have an idea about their advantages:

• Complete absence of corrosion processes. Under the condition of constant contact with water, quite significant quality;
• Absolutely smooth walls, thanks to which the pressure retains its intensity for as long as possible. In addition, there is no effect of the formation of outgrowths, which renders metal analogues unusable;

Smooth inner surface guarantees strong pressure

• Almost complete no noise emitting the transported liquid;
• Relatively low price. This is one of the most important advantages due to which most owners choose plastic pipes;
• Simple instruction performing installation work. With the help of a pipe soldering iron, reliable tight joints are easily and quickly created, since the melting point of the material in question is only 260 degrees Celsius above zero;

Do-it-yourself soldering of polypropylene pipes using a special welding machine

• No risk of ruptures as a result of freezing of the transported liquid, which is very important for external highways in winter;
• A huge number of various connecting fittings that allow laying pipelines of any complexity;
• Durability. The term of use of polypropylene exceeds 50 years.

The positive aspects of this material are obvious, but they can differ dramatically depending on the brand and type of pipes, so you should be aware of these nuances.

What to pay attention to

If you just come and order plastic pipes for yourself, then in the end you may encounter many problems during their operation or simply overpay where it is not required. To avoid such undesirable outcomes, understanding the meaning of some “little things” that you can detect even during a visual inspection of the goods will help you:

Small change #1: number of layers

In this context, we are talking about single-layer and multi-layer products. And here everything is simple:

• Single layer polypropylene pipes are cheaper and are used to create most types of pipeline systems, but are not suitable for operation at high temperatures, since they begin to deform when heated to 70-90 degrees Celsius;
• Multilayer the samples, due to reinforcement, are able to withstand much higher temperatures, although they are, accordingly, more expensive.

In order to install an apartment heating system, I recommend purchasing reinforced products. The fact is that in winter the temperature brought up in boiler rooms can significantly exceed the threshold allowed for single-layer pipes.

Trifle No. 2: marking on single-layer pipes, which determines their more accurate composition

On all plastic pipes with one layer, you can find certain designations that can be used to judge their more detailed composition and recommended scope:

Scheme of the structure of polypropylene

• High hardness;
• Lack of resistance to low temperatures

• Ventilation systems;
• Industrial pipelines

• Flexibility;
• Frost resistance

• Cold water supply systems;
• Systems "Warm floors";
• Manufacture of impact-resistant fittings and pipes

• High strength;
• The ability to withstand a short-term temperature jump up to +110 degrees Celsius;
• Restoring the shape after defrosting;
• High resistance to acids and alkalis;
• Excellent sound insulation

• Systems of cold and hot water supply;
• Systems "Warm floors";
• Heating systems in private houses;
• Compressed air systems

I recommend for home use to purchase single-layer pipes with the PPR marking, as they have the best performance characteristics, and their cost is not much higher than their less practical counterparts.

Trifle number 3: reinforcement method

If you plan to use polypropylene products when installing a heating system in an apartment, then, as I noted above, you will need multilayer reinforced samples.

They have greater rigidity and good resistance to high temperatures, for which, however, you have to put up with an increase in their cost, and in some cases also with additional difficulties during installation work, associated precisely with the need to eliminate reinforcement at the soldering point.

But in this case, I was expected to choose from the two most common options:

1. Pipe with foil interlayer. If the foil is located close to the outer side of the product, then it is removed with a shaver; if it is closer to the inner side of the product, then the cut edge is trimmed to avoid metal contact with the transported liquid. In any case, additional work in the implementation of welding is provided. In turn, such pipes are divided into the following types depending on the structure of the reinforcing layer:

• Perforated layer. This means that the foil has holes, and in the process of filling the workpiece with polypropylene, it seeps through them, creating a reliable connection without the use of glue;

Scheme of a polypropylene pipe with a perforated structure of the intermediate layer

• solid layer. In this case, there are three separate layers glued together;

Scheme of a polypropylene pipe with a continuous structure of the intermediate layer

1. Fiberglass reinforced pipe. In this case, reinforcement is performed by adding fiberglass filler to polypropylene. This approach has clear benefits:

• No need to clean the edge of the pipe before welding it;
• Increasing the coefficient of rigidity of the product;
• Decreased thermal expansion by 75%;
• Monolithic structure. There is no separation into layers in this case.

Trifle No. 4: marking that determines the pressure and temperature withstand by the pipe

Before choosing polypropylene pipes for laying a particular pipeline, you need to carefully read the designations starting with the letters PN. This "trifle" will tell you what conditions a particular product can withstand.

The classification of polypropylene pipes on this basis looks like this:

• PN 10. Suitable for transport cold water, the temperature of which does not exceed +20 degrees Celsius. Permissible pressure - up to 1 MPa;

Sample pipe marked PN 10

• PN 16. Here it is already possible to use products, in both cold and hot water supply, so they are able to withstand heating up to +60 degrees Celsius and pressure up to 1.6 MPa;

Sample pipe marked PN 16

• PN 20. There are no problems here with transporting hot liquid, the temperature of which reaches even +95 degrees Celsius. The working pressure is 2 MPa;

Pipe samples marked PN 20

• PN 25. These are already reinforced samples used in heating systems. Withstand temperature jumps exceeding +95 degrees Celsius and working pressure up to 2 MPa.

Sectional sample of pipe marked PN 25

With an increase in the number after the letters PN, not only operational properties increase, but also the cost of products, therefore, in order not to overpay, choose those pipes that exactly match your plans. That is, for example, for a cold water supply, it is absolutely not necessary to buy relatively expensive reinforced samples.

Small change #5: color

Here the opinions of experts differ. Some of them believe that the color of the pipes does not affect their technical characteristics in any way. But others reasonably point out that such marking, invested in products by manufacturers, should be taken into account. I am a reinsurer, so I take the side of the latter in this matter.

And here's what the color according to the manufacturer's version can tell:

1. White:

• Ability to withstand a pressure of 25 bar;
• Cheapness;
• Complete absence of corrosive processes;

Tubular products of white color

1. Grey:

• Thermal stability;
• Long operational period;
• Ecological cleanliness;
• Excellent tightness;

Gray polypropylene pipes

1. The black:

• UV resistant;
• High resistance to aggressive acids and alkalis;
• Resistance to the effect of drying out;
• Increased strength parameters;

Tubular products made of black polypropylene

1. Green. Cheap samples with a low operating pressure threshold, used, as a rule, for the implementation of a vegetable garden irrigation system.

Green polypropylene pipes are cheaper

As you can see, colored products can also tell some information, which, however, is more general.

Small change #6: manufacturer

You can answer, they say, this is not a car or even household appliances, so that you can also follow the brand here. But only if you deal with the products of a well-known company, you can be sure that all the designations described above will become true.

With some product of dubious origin, you may not pay attention to the marking at all, since it is most likely applied only to increase the cost.

Which polypropylene pipes are better: 6 nuances of product selection

Which polypropylene pipes are better: classification and types, instructions on how to choose, video and photo

Which company polypropylene pipes is better to choose?

Plastic plumbing systems have a number of advantages over metal ones. They are light, strong, durable, affordable. But how to choose them? After all, Wawin Ecoplastik polypropylene pipes have a wide range, and the Vostok manufacturer offers a low cost. To decide, we have prepared a detailed review of brands with all their advantages and disadvantages.

Rating of manufacturers of polypropylene pipes

The list is opened by recognized industry giants - German companies Banninger, Wefatherm, Aquatherm. The list of firms' products includes sewerage and plumbing systems, as well as fasteners and other additional components (fittings, adapters). All three manufacturers have similar markings: outlets for cold water supply are painted green, for climate systems - blue, and for heating and underfloor heating - white. Products are manufactured in accordance with European standards ISO 50001 and undergo a strict certification system

The Czech Ekoplastik and FV-Plast are slightly inferior to the German "brothers". In the post-Soviet space, these manufacturers have no analogues. Pipelines for water supply and sewerage are exported to almost all European countries. Manufacturers provide a 15-year warranty for each pipe. The material for the manufacture is a copolymer, known for its hygienic and strength properties.

Turkish Pilsa, Kalde, FIRAT, TEBO, SPK and others have gained popularity due to their affordable price. Unlike Germans and Czechs, manufacturers from Turkey do not give a guarantee of 10 years or more on their products, but they provide triple quality control. First, the raw materials are checked, then the finished product is tested for internal loads, and, finally, for external ones.

Pipe Pilsa Fiberglass

Russian, Belarusian, Ukrainian and Chinese firms close the rating of polymer pipes manufacturers. For example, RosTurPlast produces bends with EAN 13 certificate, products are regularly subjected to quality and durability checks. Plants Rozma, Teploplast, Alfa Plast, Karal Plast (Kazakhstan) and others produce ready-made plastic systems, fittings, adapters between metal and polypropylene pipes and other additional elements.

Which company to choose polypropylene pipes?

All manufacturers of polypropylene pipes guarantee the high quality of their products and their durability. Therefore, in order to decide on the choice of a plastic water supply or sewerage system, we suggest comparing finished pipes from different companies according to the following parameters:

• Main characteristics. Available diameters, non-standard connections, weight;
• Appearance. It is no secret that the Czech systems are much more beautiful than the polypropylene branches offered by Turkey. In addition, for many owners, this factor is decisive;
• Durability, strength;
• Manufacturer's warranty.

Faser pipes

The direct production of this Czech production FV Plast is divided into FV PPR and FV THERM.

• FV PPR - used for distributing cold and hot water. Designed for continuous contact with liquid at room temperature and periodic contact with hot. Normally tolerate temperature changes. Produced by welding. In addition, Faser also manufactures accessories, fittings and other necessary elements for these elbows;
• FV THERM - suitable for heating systems, connection to radiators or underfloor heating systems. They can also be used to supply hot water, but this is not practical - the cost is too high. For durability and low stretch ratio, they are made from a combination of polypropylene, rigid polyurethane and expanded polystyrene.

The average weight of one linear meter Faser is 0.1 kg. Externally, products for cold water supply are marked with stripes on white walls, and for heating - with stripes on red outlets.

Which company polypropylene pipes is better to choose?

Plastic pipes have advantages over metal ones. They are light, strong, durable and affordable. Rating of manufacturers of polypropylene pipes.

At present, the replacement of obsolete steel pipelines and the laying of new heating lines are carried out with polymer pipes of a new generation. In the ranking of popular materials for heating distribution devices, PPR pipes are on the first. The proposed information article discusses in detail the technical characteristics of the material, the main advantages and disadvantages of a polypropylene pipe for heating.

Polypropylene belongs to a group of synthetic thermoplastic polymers that change their properties under the influence of temperature. As a result of a complex chemical process using special catalysts of the organometallic group under the influence of medium and low pressure, propylene is polymerized and converted into polypropylene. The resulting material is highly resistant to an alkaline environment, as well as a high melting point, reaching 170 degrees. All these wonderful properties of polypropylene have been used in the creation of a new generation of modern polypropylene pipes for heating and hot water lines.

Reasons to choose polypropylene pipes for the heating circuit

Wiring at home or in-house starts with consultations with heating installers and shopping in search of suitable materials. Almost all experts unanimously advise choosing polypropylene pipes as the best material for a private house or replacing the central heating of multi-storey buildings.

The main motivations for choosing polypropylene pipes for heating are based on their technical characteristics. :

• Ability to withstand high pressure. Heating wiring made of polypropylene with a coolant temperature of up to 70 degrees is able to withstand operating pressures from 4 to 6 atmospheres.
• High thermal stability. In a heated circuit made of PPR pipes, the maximum water temperature is 95 degrees.
• Thermal conductivity. Due to this property, the polypropylene pipeline is not covered with condensate droplets.
• Anti-corrosion resistance for heating. Polypropylene does not react with chemicals. The inner surface is not clogged and does not overgrow with hard layers.
• Large margin of safety. Under normal operating conditions, polypropylene heating pipelines can be used for up to 50 years.

A simple technology for assembling a heating circuit, combined with a complete set of connecting and docking fittings, makes polypropylene pipes a top seller of popular polymer products.

Varieties

At the beginning of its history, PPR polypropylene pipes were out of competition, they were widely used to replace heating circuits made of steel and cast iron. A short operation of a heating system made of such elements showed a weak resistance of the material to linear thermal deformations. To save heating wiring from such unpleasant defects, polypropylene pipes were improved with internal reinforcement or, as builders call it, “internal braid”:

• From aluminium. The installation of aluminum-reinforced pipes is carried out with preliminary cleaning of the products so as not to damage the thin foil coating.

• Fiberglass. Unlike the first type, the soldering of fiberglass pipelines is performed without any special conditions.

Reinforcement of the inner part of pipes made of polypropylene made it possible to significantly reduce linear thermal deformations of the heating line.

Reinforced polypropylene pipes for heating systems

Despite the extensive line of polypropylene pipe products, not all types of polypropylene products can be used in heating systems and hot water supply. If you ask any specialist: “Which PP pipes are best for heating”, you can get an unequivocal answer that reinforced products are best suited for laying heating systems. This statement is based on a high degree of thermal expansion coefficient of products as a result of contact with a high temperature coolant. There are cases when by mistake the hot water pipeline and the heating line were mounted from ordinary polypropylene pipes and docking fittings. Under the action of the hot coolant, the laid heating branch was deformed and sagged. Horizontal wiring has lost all its appeal and turned into a wavy line.

Polypropylene pipes without reinforcement are suitable as a heating circuit of a "warm floor" heating system. In this case, the water temperature does not exceed a comfortable temperature, and in addition, the heating water pipe is rigidly fixed with a concrete screed and is less subjected to deformation tension.

Of the entire extensive family of polypropylene pipe products, only reinforced products are considered the ideal material for laying heating and hot water networks.

Diameters of polypropylene pipes for heating

The main characteristic of products is the size of the cross section - the diameter, measured in mm. The heating home network consists of different sections, which are equipped with pipes of different diameters for the best effect:

• from 100 to 200 mm are used for centralized hot water supply of multi-storey buildings, public buildings for civil purposes.
• from 25 to 32 mm are used to connect private houses and small buildings.
• Hot water is supplied through horizontal sections of wiring with a diameter of 20 mm, vertical risers are equipped with a diameter of 25 mm.

The presented table clearly shows the gradation of the change in diameter depending on the amount of heat flux.

Polypropylene fittings for heating

Pipe polypropylene products consist not only of individual linear elements, but also connecting or connecting parts, called fittings. They are necessary for interconnection, connection to vertical risers, radiators and water taps, and various other devices.

Types of heating fittings:

• Couplings.
• 45 degree or 90 degree elbows.
• Tees for connecting three sections.
• Plugs used in the dead end of the heating network or on the extreme sections of the radiators.
• Transitions from one diameter to another.
• Transitions from metal to plastic.

The exact number of fittings is determined after drawing up the wiring diagram. A graphically executed plan for the location of the heating network with the exact dimensions of each section and indicating heating radiators will help you select pipes of the desired diameter and calculate the number of connecting fittings.

Leading manufacturers

The main task of any heating heating system is to create comfortable conditions in the room during the cold season.

The efficiency of heat transfer of heating devices depends on competent installation technology and on high-quality pipe products.

Navigating brands and trademarks of polypropylene products is difficult even for specialists. In order to simplify a little the difficult choice of the right material and not make a mistake in the chosen product, we offer a top list of the best manufacturers of propylene heating pipes:

• The first place belongs to European brands. An example is the German brands Aquatherm (Aquaterm). Wefatherm (Vefatherm). Rehau (Rehau), whose products are of excellent quality and perfect manufacturing technology. The only drawback of this product is the high price.
• The second place is occupied by Czech manufacturers. Many experts note the quality of EKOPLASTIK brand products. This company was the first to launch the production of polypropylene pipes reinforced with basalt fibers, capable of competing with the best German brands in terms of quality and lower price.
• The third place belongs to the well-known Turkish companies Tebo and Kalde, which produce products of average quality and affordable price. Heating systems assembled from pipes and fittings of these brands are designed for an average service life of up to 50 years and, from a practical point of view, have no complaints.

The budget segment is represented by a line of the best Russian manufacturers PRO AQUA (Pro Aqua) and RVC, as well as the Chinese brand BLUE OCEAN. Firms have gained a good reputation and produce products of normal quality with an affordable price.

In order not to make a mistake in choosing polypropylene pipes and not to buy a fake of a well-known brand, you should carefully read the company logo on the official website, check the accuracy of the company name. It is necessary to pay attention to the evenness and smoothness of the surface, to check in practice the coincidence of the connecting fittings with the pipeline.
