The pipelines of the South Korean company Lavita Ltd are made of AISI steel
(Russian analogue steel 08X18H10). It is one of the most common grades of steel and is characterized by high formability, corrosion resistance and high mechanical properties... Pipelines of various diameters with a nominal bore from 15 mm to 50 mm allow you to implement almost any layout of the distribution pipeline of a sprinkler system
fire extinguishing.
The range of corrugated pipes consists of standard pipe and annealed pipe. Annealed pipe while maintaining all basic strength characteristics is more flexible. Therefore, it is used if the eyeliner should have more complex shape... In addition, corrugated pipe with a nominal diameter of 40 and 50 mm is produced only in the annealed version, since regular pipe these dimensions are difficult to bend.
For systems not designed for automatic fire extinguishing, the pipe is both annealed and
unannealed
The graph provides information on 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 - female thread"

Socket welded "pipe-welding"
This type of connection is designed to connect the corrugated pipe to a sprinkler distribution pipe. The coupling is made of steel and is directly welded to the distribution pipe. In a typical solution that was used before, it was necessary to first weld to the pipe a traditional welded socket with a female thread 1/2 ", and then use a socket with an external thread V / S 15 to connect the pipe.
When using a pipeline connection using a BCF15 welded socket, the cost of materials is reduced, the labor intensity is reduced, and also due to the reduction in the number of transition connections, reliability is significantly increased.
False ceiling clip
To solve a typical task - sprinkler output to a suspended ceiling, a set of equipment was developed with a V / S (F) female thread coupling and FC15 clamp. As you can see from the figure, a decorative reflector is also required to securely attach the sprinkler. This standard solution is recommended for use when using a flexible liner with a length of more than 40 cm.
In the case of using a liner of a shorter length, a situation is possible when, due to the permanent deformation of the pipe, the slabs of the suspended ceiling will move and it is necessary to take measures for their additional fixation.
When using a device for recessed mounting as a base / plinth, we recommend that you read the instructions. All materials for installation can be purchased from our company.

The use of this system is fully coordinated with the Main Directorate of the State Fire Service, which is confirmed by the conclusion of VNIIPO, the Ministry of Emergencies, 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 wide distribution received sprinkler fire extinguishing system are water-filled or air-filled installations. Of course, the most effective remedy against fire element there has always been water, although today powder and gas are also used. As a rule, a water fire extinguishing system is installed in rooms where the air temperature does not drop below 5 ° C, and the air fire extinguishing system is below 5 ° C. Automatic triggering of the installation over the fire source occurs due to a special thermal lock, which bursts or dissolves when the specified temperature of the sprinkler is reached.
Advantages of the KOFULSO sprinkler system
- No additional hardware required. Corrugated pipe made of stainless steel pipes with a wall thickness of 0.3 mm., Which easily bends without breaking its flow area, is installed without special tools... This means that installation work can be carried out without the help of specialists.
- Reliability. A stainless steel pipe is ductile and rigid: it withstands water hammer up to 65 atm, does not corrode, and sediment 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 least number of connecting parts. The liners do not require welding, therefore they are widely used for installation in suspended ceilings or in rooms with small area where such work is prohibited regulatory documents... Also, the engineers have developed a clamp for fixing the fitting in the false ceiling panel if the length of the limit switch exceeds 50 cm. It is also important that before commissioning sprinkler system is subject to an obligatory test.
Together with the Koreans, the engineers of our company have developed and offer for use clamp for fixing a flexible hose (fitting) in a false ceiling panel. This fastening system is recommended when the length of the limit switch is more than 50 cm.
It should be noted that the automatic was successfully installed in many shopping and entertainment centers - "Vegas", "Global City 2", "Golden Babylon", "Mega" hypermarket, "Vnukovo" airport, the main building of Moscow State University, as well as in warehouse and production areas, underground parking lots, water parks, office buildings. But this is not the whole list of structures where the installation of flexible pipes was made and agreed upon with the permission of the State Fire Supervision and its relevant services. Also normative documents strongly recommends using water for fires on board ships and aircraft.

Splinker fire extinguishing system
Splinker system fire extinguishing- one of the most common systems at the moment. This fire extinguishing system is used when large objects are ignited, such as entertainment centers, water parks, office buildings, underground parking lots, warehouses for various goods, etc.
The principle of operation of the system lies in the fact that through the pipeline system under pressure, water, or other fire extinguishing agent, is supplied to the spray nozzle, which distributes the liquid in the room.
Obviously, such systems require very strong but maneuverable elements. The Kolfulso company offers flexible stainless steel KOFULSO pipelines for the assembly and installation of water and foam fire extinguishing systems, equipped with brass fittings as flexible end fittings (connections).
Corrugated stainless steel pipe of the required length and two brass fittings - this is the whole set necessary to ensure that any sprinkler fire extinguishing system became more reliable and durable. The piping installation principle is quite simple. The first female threaded fitting connects the pipe and splinker, a second male fitting connects the system to the supply line (pipe).
our clients
The fire extinguishing system in the Mega hypermarket ( White dacha), at the Vnukovo airport, Moscow-City (Moscow International Business Center), in the main building of Moscow State University, the shopping and entertainment complex “Global-City-2” and many other large facilities.
First of all, it is worth noting the advantages of the pipeline KOFULSO:
Installation is carried out quickly and efficiently. Due to the flexibility of the connections and the structural features of the fittings, the installation takes place quickly and without the use of special equipment and highly qualified labor.
A sprinkler fire extinguishing system equipped with flexible pipes does not need welding. If a fire extinguishing sprinkler is installed in difficult conditions for installation, for example, on a suspended ceiling or in areas where welding is prohibited, flexible piping is ideal.
Requires no additional complex equipment or intricate tools. To install a flexible pipe fire extinguishing system, you only need a pipe cutter or grinder.
Note that, together with our Korean colleagues, our engineers have created and are proposing for use constructively new clamps for fixing flexible wiring (couplings) in false ceiling panels. This system is especially effective when the length of the limit switch is more than 50 cm.
Also for mounting automatic systems for fire extinguishing in Armstrong series suspended ceilings Colfulso offers braided and non-braided liners (FM UL standard). They, together with our mounts, are ideal for similar type ceilings.
The flexible liners that we offer are certified not only in Russian Federation, but also meet European Listed and American Approved standards.
The taps, which separately served hot and cold water... They were replaced by mixers that mix cold and hot water by changing the position of the handle of the device. In our article, we will focus on the nuances of installing a mixer on the sink.
The mixer is an integral part of the plumbing system
The correct choice of a mixer is a guarantee of 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.
Quality faucets are made of bronze or brass. Their main difference is the yellow neck of the spout of the device. If the neck 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 argue that you don't have to install it. But this is not the case. The absence of a spacer ring will cause the mixer to wobble and leak.
As for the type of spout, it is better to purchase a mixer with a swivel spout for sinks. This is explained by the fact that models in which the spout does not rotate are inconvenient to use. Often, a stream of water hits the edge of the sink or runs down the edge of the sink. Yes, and it will not be possible to properly wash when the water pours into one point.
Mixer assembly
The main elements of a mixer for large-sized 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 base plate is also used. It is attached between the shell of the sink 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
Pre-check the tightness of the lower nut. It must be passed manually along the entire thread. After tightening it, the mixer must not wobble on the sink. If this did not happen, then you were slipped a defective product.
A spacer ring is put on the base of the spout. It should fit into the groove. The ring is quite tight and may not go straight into the hole. To put it in place, squeeze it with tweezers near the incision and lift the bottom of the spout slightly. A click of the ring means it is locked correctly.
Fastening the flexible hose to the mixer
To connect the mixer to the water pipe, there is a supply line. It can be rigid (copper pipes with a diameter of 10 mm) or flexible (a hose in a metal braid, equipped with a union or union nut). Flexible eyeliner is more comfortable.
In order to qualitatively connect a flexible hose with a mixer, it is necessary to adhere to the following requirements:
- It is forbidden to mount the liner in a very taut position.
- To prevent damage and leakage, the connecting elements are not tightened to the stop.
- The eyeliner should be in its natural state, without excessive kinking or kinking.
- The diameter of the liner should be 5-6 times less than the bend radius.
- To avoid premature corrosion, it is necessary to connect elements made of matching materials (for example, steel parts are joined to steel products, brass to brass or copper, etc.).
Despite the presence in the fitting rubber seals, it is necessary to additionally use a winding material, which will improve the sealing of the joints. The best solution would be to use sanitary flax and sealant.
Flexible connection to the mixer
The tightening of the union nuts must not be accompanied by a twisting of the liner. This process involves holding the crimp sleeve with pliers. When tightening the nuts, try to twist the liner a little in the opposite direction.
Fitting the mixer to the sink
After fixing the flexible line, the fixing screws and the bottom gasket are installed to seal the mixer. Having done this, you can proceed with the installation of the mixer on the sink. Twisting of the studs is carried out. Depending on the type of construction, a screwdriver or wrench... In the second case, the nuts must be locked.
The flexible pipes attached to the mixer pass through the holes in the sink. Sometimes you may find that two union nuts do not fit into the sink hole at the same time. It becomes impossible to drop two flexible pipes at once. In this case, one supply pipe is passed into the sink, and the second is connected to the mixer through the hole.
The assembly of the lower fixture of the mixer is in progress. If the mixer is mounted on a washbasin with thin walls, the design is complemented by a plastic base plate. The nuts located on the studs are tightened with an open-end wrench.
The nuts are tightened in such a way that the mixer is securely attached to the sink. It should not move when turning the spout or water handle. But you should not overdo it with tightening the nuts either, since you can damage the surface of the sink, rip off the nuts and threads on the studs, and deform the pressure plate.
Connecting flexible pipes to the water supply
A completely logical question immediately arises: how can a flexible hose be connected to a water pipe, when twisting the fitting can be accompanied by the simultaneous unscrewing of the hose from the mixer body? To avoid this, an inlet is used, one of the fittings of which has a left-hand thread (usually it is screwed into the mixer body).
Special attention is paid to the thread of the water pipe. If it is sliced into thin or metal pipe, which will rust, a protective stainless steel tip is installed between the union nut and the thread.
Connecting the mixer to the plumbing system
The most the best solution, when, when connecting the liner to the pipe, the internal thread has a minimum length within 1.5 cm. The thread should be located on a thick wall, and screwing in the elements is carried out using a winding for sealing.
The rubber gaskets are exposed to hot water, which reduces their operational period. But this is not the only reason for their premature wear. During installation, the seals must not be turned flat or over-tightened.
The correct assembly of the gaskets is as follows. On the one hand, with the help of an adjustable wrench, the threaded connection of the water pipe is held, and on the other hand, the crimp sleeve of the union nut is held with pliers. And only after that the union nut is tightened.
When installing the mixer on the sink, there are a number of nuances that will help to carry out this work better and in a short time. In particular, it is possible to make it easier to work with a flexible hose if the hose pipes have different lengths. At installation works the fittings on the two liners will not interfere with each other, and they will pass through the hole in the sink in turn.
If a new sink was bought together with the mixer, then its fastening is carried out on a not yet fixed structure. This will make it more convenient to install the mixer. The installation of the sink will be carried out with the mixer already installed on it.
When replacing an old mixer, you may encounter the problem of its high-quality dismantling. Unscrewing the mixer may damage the water pipe since precipitated salts are often the reason for the tight "sticking" of the compounds. This problem is solved with the help of brake fluid, which is used to process the joint. After 15-20 minutes, the mixer will unscrew without any problems.
Sometimes it happens when the fixing element of the mixer has an unsuccessful design. For example, when the fastener consists of a thin pressure plate and a stud that is offset to the extreme. It will not be possible to securely fix such a fastener, since it will be qualitatively attached to the sink only at one point. As a result, the formation of a gap may occur in the area opposite this point. To prevent water infiltration, this gap is sealed with silicone sealant.
