The pipelines of the South Korean company Lavita Ltd are made of AISI steel

(Russian analogue steel 08Х18Н10). It is one of the most common grades of steel and is characterized by high formability, corrosion resistance and high mechanical properties. Pipelines various diameters with a nominal bore from 15 mm to 50 mm allow you to implement almost any distribution pipeline scheme for a sprinkler system
fire extinguishing

The range of corrugated pipes consists of standard pipe and annealed. The annealed pipe, while maintaining all the basic strength characteristics, is more flexible. Therefore, it is used if the eyeliner must have more complex shape. In addition, corrugated pipes with a nominal diameter of 40 and 50 mm are produced only in an annealed version, since a conventional pipe of this size is difficult to bend.

For systems not intended for automatic fire extinguishing, pipe both annealed and
unannealed

The graph provides information about hydraulic losses in the pipe depending on the speed of fluid movement. For ease of use, the graph contains lines for converting the speed of movement from gallons per minute to a more familiar format for us - meters per second.

Coupling “Pipe - internal thread”

Coupling "Pipe - internal thread» is designed to provide a tight connection between a corrugated pipe and equipment or with an external thread. Mainly such equipment are sprinklers. Depending on the size of the external thread of the sprinkler, the required coupling is selected. So, for example, for sprinklers of type SVN=12 it is necessary to use coupling V/S (F) 15.

Welded coupling "pipe-welding"

This type of connection is designed to connect corrugated pipe to sprinkler distribution piping. The coupling is made of steel and is directly welded to the distribution pipe. In the typical solution that was used in the past, it was necessary to first weld a traditional weld-on coupling with a 1/2" internal thread to the pipe, and then use a coupling with external thread V/S 15.

When using a pipeline connection using a BCF15 welded coupling, the cost of materials is reduced, labor intensity is reduced, and reliability is significantly increased by reducing the number of transition connections.

Suspended Ceiling Clamp

To solve typical task- outlet of the sprinkler to a suspended ceiling, a set of equipment was developed: a coupling with internal thread V/S(F) and a clamp FC15. As can be seen from the figure, a decorative reflector is also needed to securely attach the sprinkler. This standard solution is recommended for use when using flexible eyeliner with a length of more than 40 cm.

In the case of using a shorter length of liner, a situation is possible when, due to residual deformation of the pipes, the suspended ceiling slabs will shift and it is necessary to take measures for their additional fixation.

When using a deep-mounting device as a base, we recommend that you read the instructions. You can purchase all materials for installation from our company.

When creating a network of distribution pipelines of considerable length, it is impossible to do without connecting couplings. These same couplings can be used in case of repair of damaged sections of corrugated pipe. To make the transition from a larger diameter pipe to a smaller one, it is necessary to use reduction couplings.

A rack fastening was developed especially for the Armstrong type ceiling for rigid fixation of the liner on the suspended ceiling guides. This system allows you to adjust the position of the sprinkler in height.

				Using a roller pipe cutter, carefully cut a piece of pipe to the required length. In the cutting area, the pipeline must be straightened so that it does not have bends at the cut point. The pipe must be cut strictly evenly between the corrugations, avoiding creases and kinks in the cutting area. Make sure that the cut is made smoothly, perpendicular to the pipe axis, without burrs, bends or other deformations of the pipe in the cut area.
				Inspect the connection fitting for all components and their correct location. Insert the piece of cut pipe all the way into the fitting from the union nut side. Secure the fitting by lightly tightening the nut by hand, then finally tighten the nut with two spanners as shown in the figure.

Taps that separately supplied hot and cold water. They have been replaced by faucets that mix cold and hot water by changing the location of the device handle. In our article we will talk about the nuances of installing a faucet on a sink.

The mixer is an integral part of the plumbing system

Choosing the right mixer is the key to long-term and convenient use of the product.

When purchasing a mixer, you should pay attention to:

• the material from which it is made;
• sealing parts;
• spout type

High-quality faucets are made from bronze or brass. Their main difference is the yellow spout neck of the device. If the cervix gray, then the mixer is made of silumin. This material wears out quickly due to corrosion.

The sealing elements must be rubber. The mixer kit must include a split spout spacer ring. Some unscrupulous sellers claim that it does not need to be installed. But that's not true. The absence of a spacer ring will cause the mixer to become loose and leak.

As for the type of spout, for sinks it is better to purchase a faucet with a swivel spout. This is explained by the fact that models whose spout does not turn are inconvenient to use. Often the stream of water hits the edge of the sink or flows down its edge. And you won’t be able to wash your face properly when water is pouring into one point.

Mixer assembly

The main elements of a mixer for large sinks (made of stone or cast iron) are:

• 1-2 stud screws;
• a pressure plate having a rubber gasket;
• nuts

If the sink is made of light stainless steel (for example, a kitchen sink), then a plastic support plate is also used. It is attached between the shell body and between the rubber gasket of the pressure plate. Plastic plate will provide the mixer with a more rigid attachment to the sink.

Mixer assembly

The tightness of the lower nut is first checked. It must be done by hand along the entire thread. After tightening it, the faucet should not wobble on the sink. If this does not happen, then you were given a defective product.

A spacer ring is placed at the base of the spout. It should fit into the groove. The ring is quite tight and may not immediately fit into the hole. To put it in place, it should be squeezed with tweezers near the cut, and the lower part of the spout should be lifted slightly. The click of the ring means it is locked correctly.

Attaching flexible hoses to the mixer

A liner is provided to connect the mixer to the water pipe. It can be rigid (copper tubes with a diameter of 10 mm) or flexible (a metal braided hose equipped with a fitting or union nut). Flexible eyeliner is more convenient.

In order to properly connect the flexible hose to the mixer, you must adhere to the following requirements:

1. It is forbidden to install the liner in a highly tensioned position.
2. To prevent damage and leaks, the connecting elements are not tightened all the way.
3. The eyeliner should be positioned in its natural state, without excessive twisting or kinking.
4. The diameter of the liner should be 5-6 times less than the bending radius.
5. To avoid premature corrosion, it is necessary to connect elements from compatible materials (for example, steel parts are joined to steel products, brass to brass or copper, etc.).

Despite the presence of rubber seals in the fitting, it is necessary to additionally use winding material, which will improve the sealing of the connections. The best solution would be to use sanitary flax and sealant.

Flexible connection to the mixer

Tightening the union nuts should not be accompanied by turning the connection. This process involves holding the crimp sleeve with pliers. When tightening the nuts, you should try to twist the line a little in the opposite direction.

Installation of a faucet on a sink

After fixing the flexible hose, install the mounting screws and the bottom gasket to seal the mixer. Having done this, you can begin installing the faucet on the sink. The pins are tightened. Depending on the type of construction, a screwdriver or spanner. In the second case, the nuts need to be locked.

Flexible hoses attached to the faucet are passed through holes in the sink. Sometimes you may encounter that two union nuts do not fit into the sink hole at the same time. It becomes impossible to lower two flexible hose tubes at once. In this case, one liner tube is passed into the sink, and the second is connected to the mixer through a hole.

The lower fastening of the mixer is being assembled. If the mixer is mounted on a sink with thin walls, then the design is complemented by a plastic support plate. The nuts located on the studs are tightened using an open-end wrench.

The nuts are tightened in such a way as to ensure reliable fastening faucet on the sink. It should not move when turning the spout or water handle. But you shouldn’t overdo it with tightening the nuts either, since you can damage the surface of the sink, tear off the nuts and threads on the studs, and also deform the pressure plate.

Connecting a flexible line to the water supply

A completely logical question immediately arises: how can a flexible hose be connected to a water pipe, when tightening the fitting can be accompanied by simultaneous unscrewing of the hose from the mixer body? To avoid this, a liner is used, one of the fittings of which has a left-hand thread (usually it is screwed into the mixer body).

Particular attention is paid to the thread of the water pipe. If it is sliced ​​thin or metal pipe, which will rust, then a stainless steel protective tip is installed between the union nut and the thread.

Connecting the faucet to the plumbing system

The most best solution when connecting the liner to the pipe, the internal thread has a minimum length of 1.5 cm. The thread must be located on a thick wall, and the elements are screwed in using a winding for sealing.

Sealing rubber gaskets are exposed to hot water, which reduces their service life. But this is not the only reason for their premature wear. During installation, seals must not be turned flat or over-tightened.

The correct assembly of the gaskets is as follows. On one side, use an adjustable wrench to hold the threaded connection of the water pipe, and on the other side, use pliers to hold the crimp sleeve of the union nut. And only after this the union nut is tightened.

When installing a faucet on a sink, there are a number of nuances that will help carry out this work more efficiently and in a short time. In particular, it can be easier to work with flexible hoses if the hoses have different lengths. During installation work, the fittings on the two connections will not interfere with each other, and they will fit into the hole in the sink one after another.

If a new sink was purchased along with the faucet, then its fastening is carried out on a structure that has not yet been fixed. This will make it more convenient to install the mixer. The sink will be installed with the faucet already installed on it.

When replacing an old mixer, you may encounter the problem of its quality dismantling. Unscrewing the faucet can damage water pipe, since settled salts often cause tight “sticking” of compounds. This problem is solved with the help of brake fluid, which is used to treat the joint. After 15-20 minutes the mixer will unscrew without problems.

Sometimes it happens when the faucet fastening element has an unsuccessful design. For example, when the fastener consists of a thin pressure plate and a pin, which is shifted to the outer part. It will not be possible to securely fix such a fastening element, since it will only be properly attached to the sink at one point. As a result, a gap may form in the area opposite this point. To prevent water seepage, such a gap is sealed with silicone sealant.

Example of using a pipeline KOFULSO for installation of a water fire extinguishing system
Object: archive of the insurance company "INGOSSTRAKH".

Installation of an automatic fire extinguishing system in the offices of a business center.

The use of this system is fully agreed with the Main Directorate of the State Fire Service, which is confirmed by the conclusion of VNIIPO, the Ministry of Emergency Situations, as well as a fire safety certificate.

In the pipeline market, the South Korean company Kofulso has established itself as a company that produces quality products for all water supply, heating and gas supply systems. All products have an international standard - European and American quality certificate. Today it has become widespread fire sprinkler system- these are water-filled or air installations. Of course, the most effective means Water has always been used against the fire element, although today they also use powder and gas. As a rule, a water fire extinguishing system is installed in rooms where the air temperature does not fall below 5°C, and an air fire extinguishing system - below 5°C. The automatic activation of the installation above the source of fire occurs due to a special thermal lock, which bursts or unsolders when the specified temperature of the sprinkler is reached.

Advantages of the KOFULSO sprinkler system

• No additional equipment. A corrugated stainless steel pipe with a wall thickness of 0.3 mm, which bends easily without disturbing its flow area, is installed without special tools. This means that installation work can be done without the help of specialists.
• Reliability. A stainless steel pipe is ductile and rigid: it can withstand water hammer up to 65 atm, does not corrode and sedimentary materials do not remain on its walls.
• No welding. Brass fittings reliably connect flexible hoses to each other, as well as complex routes - with the smallest number of connecting parts. The connections do not require welding, therefore they are widely used for installation in suspended ceilings or in rooms with a small area where such work is prohibited regulatory documents. The engineers also developed a clamp for fastening the fitting in a suspended ceiling panel if the length of the end cap exceeds 50 cm. It is also important that before putting it into operation sprinkler system subject to mandatory testing.

Together with the Koreans, our company’s engineers have developed and offer for use clamp for fastening a flexible connection (fitting) in a suspended ceiling panel. This fastening system is recommended for end cap lengths greater than 50 cm.

It is worth noting that automatic has been successfully installed in many shopping and entertainment centers - "Vegas", "Global City 2", "Golden Babylon", "Mega" hypermarket, "Vnukovo" airport, main building of Moscow State University, as well as in warehouse and production areas, underground parking lots, water parks, and office buildings. But this is not the entire list of structures where the installation of flexible hoses was carried out and approved with the permission of the State Fire Inspectorate and its relevant services. Also, regulatory documentation strongly recommends the use of water in case of fires on board ships and aircraft.

Splinker fire extinguishing system

Splinker system fire fighting- one of the most common at the moment systems This fire extinguishing system is used when fires occur in large facilities, such as entertainment centers, water parks, office buildings, underground parking, warehouses for various goods, etc.

The principle of operation of the system is that through the pipeline system under pressure water, or other fire extinguishing agent, is fed to a spray nozzle, which distributes the liquid in the room.

It is obvious that such systems require very durable but maneuverable elements. The Kofulso company offers flexible stainless steel KOFULSO pipelines equipped with brass fittings as flexible ends (connectors) for the assembly and installation of water and foam fire extinguishing systems.

A corrugated stainless steel pipe of the required length and two brass fittings - that’s the whole kit necessary for any fire sprinkler system has become more reliable and durable. The principle of installing the pipeline is quite simple. The first female fitting connects the pipe and splinker, the second male thread fitting connects the system to the supply line (pipeline).

Our clients

The fire extinguishing system in the Mega hypermarket is equipped with KOFULSO flexible hoses ( Belaya Dacha), at the Vnukovo airport, Moscow-City (Moscow International Business Center), in the main building of Moscow State University, the Global City-2 shopping and entertainment complex and many other large facilities.

First of all, it is worth noting the advantages of the pipeline KOFULS:

Installation is carried out quickly and efficiently. Thanks to the flexibility of the connections and the structural features of the fittings, installation is quick and without the need for special equipment and highly qualified workforce.

The fire extinguishing sprinkler system, equipped with flexible hoses, does not require welding. If the fire extinguishing system sprinkler is installed in difficult conditions installation, for example, on a suspended ceiling or in rooms where welding is prohibited, a flexible pipeline is an ideal option.

Does not require additional complex equipment or intricate instruments. To install a fire extinguishing system with a flexible pipeline, you only need a pipe cutter or grinder.

Let us note that together with our Korean colleagues, our engineers have created and offer for use structurally new clamps for securing flexible wiring (couplings) in suspended ceiling panels. This system is especially effective when the end length is more than 50 cm.

Also, for the installation of automatic fire extinguishing systems in suspended ceilings of the Armstrong series, the Colfulso company offers liners with and without braiding (FM UL standard). They, together with our fasteners, are ideal for this type of ceiling.

Flexible eyeliners that we offer are certified not only in Russian Federation, but also meet European Listed and American Approved standards.
