It is also possible to make a network of tubinglines completely sealed, so it began boldly to hide under the walls and floors and art to solve the problem without looking at permanently preventing the tubing.

Plumbing from PEX tubing less clogged, it does not fear stray currents and intermittence. Time of installation of the system is reduced by 2-3 times, and cost – by 10-20%. The service life is increased by approximately 50 years.

For plumbing use thin-walled tubes (thickness up to 3,5 mm) of three types of plastic: polyvinyl chloride (PEX), high density polyethylene (HDPE) and polypropylene (PP).

In Russia, PEX tubing are successfully used for several decades, because they are relatively cheap.

However, widespread use of household chemicals, washing and dishwashing machines with a high temperature of diverted water, forced to seek a replacement of more heat and chemically resistant materials.

So in practice include polyethylene and polypropylene. In the Russian market their products to domestic Plumbing is now offering about 20 firms.

The table lists the approximate prices for tubing, prices for “fasoninu also vary widely: in one firm tubing are cheaper, but a sort of” fasonina “to them more expensive in the other – quite the opposite.

The range of fittings for different companies ranging from 5 to 30 names and from 3 to 10 sizes of each item (not including gaskets).

The most complete and rapid acquisition systems provide: among foreign firms – REHAU (Germany), NICOLL (France), ONNINEN (Finland), and among domestic – LLC AGRIGAZPOLIMER (PEX tubing), ZAO Teploimport and NPO STROYPOLIMER ” (tubes made of PP).

Recently appeared on the market noise absorbing plastic tubes with mineral filler (and the firm REHAU POLOPLAST), which when being used, the noise level is reduced by almost 2-fold, compared with tubes made of polypropylene, but its cost – almost twice as high.

To build the tubingline, as a rule, use tubing and fittings of the flare and o-ring of high-quality rubber, which should be leak-proof connections for decades.

For PEX tubing is sometimes used bonding, and tubing made of PP can be joined by fusion welding.

Sizes of PEX tubing

Therefore, Plumbing systems must be periodically cleaned. For this tubingline provides so-called “audit” (sealing hatches) and “cleaning” (holes in the wall of the tube, closed tube).

They are put where the flow of water dramatically alter the character of motion, for example, to place the accession of several tubing, a sharp bend, indented (a small break on the risers), as well as on the issue.

For reference. When emptying a full sink basin holds more than 12 seconds, and full bath – more than 180 seconds, then tubinglines have already begun to become obstructed.

Education sediments may slow “catcher” (Air separator), installed at the outlet of a sink.

The more one-off (“volley”) water consumption, the better it is self-cleaning of tubing and vice versa.

Beautiful imported toilet flush, low-capacity, of course, saves water (for what was done), but it is not conducive to self-cleaning tubing in our plumbing systems.

Well, if we increase the slope of PEX tubing? Stream will flow, of course, a little faster, but the thickness of the liquid layer becomes smaller, and with a small amount of waste, large items will settle to the bottom.

The same happens when an unjustified increase in the diameter of the PEX tubing at a constant volume of effluent.

PEX Connection Systems

First, the easiest, but at the same time, the most uneconomical – often to pour as much water from the devices.

Second-grade to make arbitrary, based on the range of 2-10% (the shorter the issue – the more the slope). In this case, set to release “cleansing” and periodically clean out his mechanical means, which is quite troublesome.

Note that cleaning the tubing “chemistry”, for example, means “The Mole” and so forth, you can destroy the microorganisms that break down waste in Plumbing treatment plants cottage, and, thus, delaying the clearance of waste for 2-3 months.

A more reliable but more expensive way – is to set the base of the riser team capacity and its periodic emptying of fecal pump, for example, echo sounder airlift, etc.

Note that the forced pumping effluent as an alternative to abstraction by gravity, is used increasingly.

For example, in the regeneration of large houses, where, at the request of the owner, sanitary devices placed in the building is chaotic, or western renovation of the old city apartments.

Major causes of penetration of gases from the Plumbing in the room three: looseness in the joints of the tubingline network, a crack in the rubber sleeve on the flush and the breakdown of hydraulic seal any instrument.

pex pipe

Most popular – polypropylene pipes, or rather PPRC-3 (Poly Propylene Random Copolymer). These pipes are suitable for hot and cold water, heating.
Mounting PEX pipes

In addition to its excellent quality and many operational advantages, PEX pipes is also very easy to install. Welding of PEX pipe does not take much time, does not make no noise, no dirt, or any other unpleasant effects.

The fact that the ration PEX pipes can be accomplished in the shortest possible time, allows you to work in virtually any conditions. When installing the polypropylene tubes used apparatus for welding of PEX pipe, which can be reliably welded pipe, providing them with a strong connection with each other.

Soldering PEX pipes does not require special security measures. Soldering PEX pipes is very easy to carry and operate, it works on the mains voltage 220V and quickly solder PEX pipes together with fittings.

White pex pipe

Removal of the bolt failure – the case more serious, as it requires a full examination of the system, and sometimes its alteration.

The fact that the waste water pouring out of drainage in the riser, cover part of its cross section and further draining down, carries with it the air (“ejecting” air).

If the top of riser will do an adequate amount of air, the lower level entrance, the deficit of the liquid air there will be no pressure will be equal to atmospheric. Otherwise, there will be dilution.

If it is large, the water from the hydraulic seal will be drawn into the challenge, and then the path of gases in the room – is open. In this case, they say that “there was a breakdown of the gate.

The greater the volume of waste water to stand tubing and the diameter of the outlets, the closer to 90 ° angle to the disqualification of accession stand tubing and the lower the height of the gate, the greater the likelihood of such an accident.

In Canada produce Taco valves on a 50, 60 and 70 mm. With the purchase of imported bathroom complete with siphons necessarily pay attention to the height of the gate.

The problem of breakdown of the closures affects the construction of the riser, and the design of the hood. For example, how to arrange the hood of the toilet riser, located in the one-storey annexes cottage? Instead of windows the 2 nd floor?

PEX pipe – pipes made of chemically modified polyethylene. The technology of production and modification of polyethylene pipe to create a higher quality characteristics and possessing new properties.

pex pipe

This is achieved through a special technology so-called crosslinking, which provides the molecules crosslink polyethylene. This process makes PEX Pipe PEX so dense and strong.
Basic properties of PEX pipes

# Flexibility and memory shape.
# Stability at the maximum temperature up to +95 degrees Celsius and a maximum atmospheric pressure to 10 atm. We should respect the rules and operating conditions.
# Application antikislorodnogo barrier, which prevents the penetration of oxygen into the tube, which ensures long life PEX pipes
# The smoothness of the inside of the tube, which prevents accumulation of dirt and mud. This property guarantees the longevity of the pipe and the purity of water supplied.
# Resistance to chemical influences, solvents, allowing use of plastic pipe and for the filing of fluids in the workplace.
# High elasticity of the pipe, which prevents the formation of cracks and wrinkles, even with prolonged exposure and heavy load, including at high temperatures.
# Resistance to abrasion. This property provides a long service life PEX pipe even in areas that are subjected to constant mechanical stress.
# High resistance to electric current. PEX pipe, as any polyethylene pipes are resistant to stress and do not conduct current. This allows their use in all institutions, residential zhomah and enterprises.
# High strength. Technologies and production methods PEX pipes, you can create high-strength pipes for water supply, gas supply, sewage systems and other life support systems.

Stoyan at the upper equipment finish cleaning, and the carts to make it a tubing of larger diameter.

The possibility of using such a construction be sure to check the calculation. That extra chores completely pay off the cheapening of the system and the possibility of new planning decisions.

If the home will be a few risers, for example, if the toilets are located on opposite sides of a house or set a lot of devices of different types, the risers in the attic can be brought together in a tube and make a hood.

In any case, even one risers in the house should be ventilated.

Extracts have no closer than 4 m from the windows and balconies and are bringing into 0,3-0,4 m above the roof.

Higher tubing in the winter ice more quickly slaughtered due to condensation of moisture from the plumbing gases. And that means the inevitable breakdown of the closures. Deflector on the hood is better not to – it contributes to its intermittence.

From the foregoing it follows that the problem of choosing a plumbing downright like a legendary hero: wherever you go – always something to lose. And to solve it sensibly, by forces only specialist.

Of course, you can change yourself a pair or two tubing or install a new device in the house. However, serious modernization of the system, and even more so, its development and installation of a new home, despite its apparent simplicity, after all, with qualified professionals.
Recommendations landlord

If the devices of the upper floor constantly disrupts the closures are likely clogged or peremerzla hood. If disruptions occur periodically at the instruments on different floors, so improper diameter riser.

If on the ground floor there is release of water from the shutter device in a bowl, then most likely clogged issue.

When leaving the family for a long time do not forget to pour a tablespoon of vegetable (engine) oil in the siphon devices. This will prevent excessive water evaporation and entry into the house gases.

If the winter heating accounts off, it is necessary to pull water from the cisterns in the toilets and remove it from the closures.

Production of PEX pipe has a rather wide range, among which there are PEX pipes, from the combined material. For example, the widely used PEX Pipe AL, made of metal plastic, having quality characteristics and indicators of resilience.

Scope PEX pipe is wide enough. The first is the life support system of residential houses.
Applications PEX pipes

1. The hot and cold water (PEX Pipe Uponor and others). The temperature of water supplied may vary from 0 to 60 degrees Celsius. For the different temperature of water used different series of PEX pipes. Operating pressure, it also varies depending on a series of pipes and class exploitation.

2. Heating systems radiator type (PEX pipes Barbi, and others). PEX pipe for heating systems can withstand water temperatures up to +90 degrees Celsius. Operating pressure in such pipes is allowed to 0,6 MPa and 1,0 MPa, depending on the series of tubes.

3. Heating systems floors and walls. For heated floors and walls are used PEX pipe, resistant to water temperature to 70 degrees Celsius. Operating pressure at the same time is the same as for the pipe radiator heating, ie up to 0,6 MPa and 1,0 MPa depending on series.

4. Trunk pipelines of heating systems. It can be used tubes of different series, depending on the nature of the heating system.

This is only the basic scope of PEX pipes. PEX pipes can also be used in the heating system in the heating of the collector and lezhakovogo type of heating systems with open and hidden wiring.

In general, such a widespread use of PEX pipe and rightly so. In addition to these properties, they have an array of advantages over metal pipes. For example, PEX pipes for drinking water do not attach extraneous water tastes and smells, do not affect its composition and does not emit harmful pollutants into the water. In addition, these pipes are not decreasing in the inner diameter, which can not escape the metal pipes because of corrosion and various kinds of growth.

Another important advantage of plastic pipes and PEX pipes before the metal is their capacity to depreciation in the abrupt change of pressure. This property is very useful, for example, in cases such as a sharp close the water tap. This hydraulic shock in the tubes several times smaller compared with tubes made of metal.

However, the question as it might seem, would not the practice of advertising or driving lessons, but the sad examples of unprofessional or even worse, intentional approach to bringing the tubing of polymer materials to the consumer.

The very first thing that interested buyer – the possible scope of tubing and the main operating parameters. Given that PEX tubing have been widely used in Russia for domestic water and heating systems only in the last four years, yet for some of these products are a novelty, so the temptation to offer a consumer plastic tubing, which “might” work everywhere, even in systems heating with superheated steam, alas, is too large.

So, after visiting the exhibition or in the office of a company, you get a booklet (or hot assurances), in which black and white – working temperature “our tubing” (mostly Metal) +95 ° C, pressure 0.1 MPa. Lifetime while 50 years! But it’s not all. In order to finally slay the client, followed by a modest posPEX Universeript: “possibly short-term increase in temperature up to +110 ° C” (the record of such a “possible” increase, as recorded by the author, +135 ° C). Needless to say, such a fantastic settings have on inexperienced consumers magical effect. As a result of PEX tubing installed in the heating systems, where the coolant used superheated steam. Taking place due to the amateurish approach of the accident completely wrongly formed a negative attitude to PEX tubing. It is doubly a pity that in Russia the same “rake” is already advancing in the 60’s, when polymer materials and the experience of their practical application were a novelty.
At the same time, industrialized countries have relied on improving the regulatory framework governing the use of PEX tubing. As a result – today more than 80% of tubinglines are made of polymer materials. The low accident rate and a high degree of reliability and durability of plastics engineering services provided by, firstly, clear by following the requirements specified in the regulations and, secondly, by a qualified installation of tubinglines, which must be performed by professionals who have special training and have the corresponding license for such work.

According to specialists, more than 60% in the basements of residential buildings have been at least once flooded by Plumbing because of the clogging Plumbing tubing.

Our article on how to reduce the risk of problems with Plumbing in the house and as easy to deal with them.

Work plumbing

In addition to flooding, Plumbing facilities, in-house Plumbing surprises in the form of leaks, specific smells, frightening noise. Yes, and aesthetics cobwebs visible tubing are not too attractive.

To foresee any problems can be expected from Plumbing, it is useful to understand the essence of its design and operation principle.

The network of tubinglines and plumbing fixtures (the “instruments”), collecting and abductors used water and waste (except rain water) inside the building, called Intra, and more often – the internal plumbing system.

From each device (sink, bath, toilet, etc.) drains through the outlet tubing are placed in a horizontal FLOOR withdrawal from it – in the riser, ie, a vertical tubing.

In the basement of the house riser smoothly into a horizontal tube-production, waste water outlet of the building under the ground (below the freezing depth of soil).

Further, they are sent through the tubing or in the observation well, and from it – in the network outside plumbing or septic tank in the local treatment system.

The upper part of the riser is displayed above the roof of the house and called a hood. Through it discharged into the atmosphere gases from the outdoor sanitation.

Water from swimming pools, water heaters, heating systems and water purification is also diverted into the plumbing.

plumbingage Network originally created as nonpressure, gravity. Therefore, in all its horizontal sections are provided, small (1-4%), but strictly controlled by the gradients of tubinglines, along the drain water.

tubing connection in an extensive network of exercise with the help of special fasteners (tees, bends, crossings, etc.). They are called fittings or fasoninoy. Such elements, to connect one device, takes 3 to 6 pieces.

To plumbing gases do not fall into the room, each device added to the taps through a special device that works as a water seal. Plumbers usually call them “siphons”.

Lock – is, in fact, loop or U-shaped tube, half filled with water. Water and serves as a barrier to the removal of gases from the room (in the toilet bowls and traps are provided embedded in the design of the gates).

The network configuration, and hence its value, above all, depend on the number and placement of devices in the home. The cost of plumbingage system in the modern cottages ranging from 1 to 5 thousand dollars, on risers.c

Polypropylene tubing and fittings are designed for domestic hot and cold water, warm floors and wiring of central heating systems with operating temperature up to +95 C.

Use polypropylene tubes can be virtually any of the existing date fields where tubing are used: to take stock of drinking water to supply coolant to the radiator, drainage, irrigation, etc.

Also, what is particularly valuable, PEX belongs to a class of polyolefins, and like all members of this class, is an environmentally friendly product, transferring their money on products made from it and ensuring the security of the process.

To this we can only add that the reliability of welded joints – the highest as compared with other methods and approaches in strength to the tubing itself.

Polypropylene tubes are undeniable advantages:

* Low cost
* Easy installation
* Speed of installation in the polypropylene tubes 5-7 times faster than the metal
* Reliability and durability of polypropylene tubing meet the highest requirements
* Polypropylene tubes can be used, while maintaining their original characteristics over 50 years in the cold water and at least 25 years in systems for hot water and heating.

Specially designed corrugated outer surface makes tubing are resistant to stress. Thanks to flexible tubing structure any seismic movement of the soil did not influence them.

Characteristics of polyethylene provide resistance to being in the wastewater chemicals.

Temperature-resistant up 80oS

The smooth inner surface and low coefficient of friction provide high speed transmission drains. The degree of smoothness of the inner surface of tubing Firat (FIRAT) is close to the index of smoothness of the surface of the glass, so the tubes do not form deposits.

Corrugated tubing can be used not less than 50 years and work with, like the first day of pads.

Owing to the peculiarities of the molecular structure of polyethylene corrugated tube elastically deformed under the influence of loads, absorb external loads, and again take its original shape. Boundary constant strain can grow to 7.5%. While the other tubing in such a strain burst, corrugated continue their work.

The smooth inner surface and low coefficient of friction PEX tubing provide high speed transmission drains.

The degree of smoothness of the inner surface of tubing PEX close to that smoothness of the surface of glass, so the tubing FKS not form precipitation.

* PEX tubing have high durability.
* PEX tubing, made from polyethylene (HDPE), are resistant to the effects of UV rays.
* PEX tubing are resistant to high temperatures: 60 ° C for HDPE and 95 ° C for PEX tubing.
* PEX tubing absolutely shockproof.
* PEX tubing resistant.

With its high impact strength and elastic structure, PEX tubing are resistant to seismic movements of the soil.

During transportation and storage of tubing FKS can use telescopic method (tubing in tubing), thus significantly saving space and place.

Using the method of electro-fusion welding at the closed area provides an opportunity to dig a narrow channel for the tubing. Accordingly, reduced labor costs and timing of works.

PEX tubing, connected electro-fusion welding, have absolute tightness and a high degree of security.

Designated transportation and storage of any food can also be equipped with products PEX. Due to properties, HDPE (high density polyethylene), which is used in the production of PEX systems, is absolutely hygienic.

The inner surface of tubing walls PEX made in bright colors, which contributes to the reflection of light. This makes it possible to carry out visual inspection of the inner surface of the tubing with your camcorder.

If necessary, PEX tubing can be made with special coated (PE-el), which promotes the release of static electricity.

In many major cities and regions of USA operated many kilometers of water networks of the traditional slip-joint tubing, at which accidents occur largely because of depressurization of butt joints and fractures of the tubing. Strong welded joints – one of the advantages of high-pressure polyethylene tubing.

In addition, we note that during the two major earthquakes in Japan in 1995 and 2000 were not only damaged tubinglines from PEX tubing.
In Russia, large-diameter polyethylene tubing have been applied a few years ago. Initially they were mainly used in the construction of non-pressurized reservoirs. However, in recent years, large-diameter polyethylene tubing are increasingly and actively used in construction of high-pressure water mains.

tubing of large diameter and long use in their projects by Turkish company Firat. Among the most interesting projects planned by this company in the near future, it should be noted the project on construction of plumbing of fresh water with a diameter of 1600 mm. between the mainland Turkey and Cyprus. The uniqueness of this project is rather that the aqueduct would have to “hang” in the sea water, bending to a greater depth (this depth is chosen specifically to minimize the probability of collision with the pipeline floating).

Invented by KrahGmbH technology has been adopted worldwide and became the final decision, especially for Plumbing systems. Firat Company is proud that she had the honor to represent the production technology spiral tubing (FKS), thanks to technological partnership with the corporation KrahGmbH.

FKS tubing found application in many fields, such as: Waste water treatment plants, Plumbing systems, marine collector, industrial ventilation systems, industrial tanks and storage facilities for chemicals, irrigation systems, storage of methane gas, etc.

PEX tubing found application in many fields, such as: Waste water treatment plants, Plumbing systems, marine collector, industrial ventilation systems, industrial tanks and storage facilities for chemicals, irrigation systems, storage of methane gas, etc.

PEX tubing are manufactured with a diameter up to 3.600 mm.
Depending on the specification, FKS tubing are made of high density polyethylene (HDPE) or polypropylene (PP).

Pipes can be used in a variety of – steel (black and stainless), copper, plastic, metal. Type of pipe used depends on the design of the heating system and is chosen for reasons of the given characteristics: hydraulic, operational, economic and environmental.

Today the building is widely used PEX tubing. On the positive properties of PEX is its reduced flammability and increased chemical resistance compared to other polymers. It is also less sensitive to UV radiation.

Compared with polyethylene, PEX tubing have higher performance. PEX has the lowest coefficient of thermal linear expansion compared with other polymers are used: for comparison – 2 times smaller than that of polypropylene.

Among the general advantages of PEX tubing should be attributed durability and environmental friendliness.

PEX tubing are absolutely smooth, so a minimal resistance to fluid motion, not corrode and have a high plasticity.

Making a decision of what material to choose tubing for the construction of various engineering systems, especially when it comes to external networks, pay attention to the substantial difference in assembly technology systems. Thus, for polyethylene tubing should be expensive, energy-intensive and heavy welding equipment, work which requires highly skilled personnel (important human factor, which can not be avoided!), As well as certain working conditions. In the case of PEX tubing – installation requires a very simple lever hardware. Installation of PEX tubing takes much less time than the welding of polyethylene tubing.

The main areas of PEX tubing are a drain system and the external and internal drainage.

For PEX tubing is characterized by one common factor – an excellent price / quality ratio.

Concern “Rehau” uses to make their profiles about 60 (!!!) different chemicals. Each of them has a different purpose: and plasticizers, and catalysts, and substances that protect plastic from the decomposition and discoloration, etc.

It is noteworthy that the concern Rehau was the first company to produce translucent structure, which ceased to use cadmium in the manufacture of windows.

Rehau has its own chemical laboratory, which develops new formulations that are used subsequently in the manufacture of windows, and checks them. Accordingly, the material obtained is absolutely environmentally safe – its use is permitted even in hospitals, as confirmed by the presence of the hygienic certificate.

Pipes can be used in a variety of – steel (black and stainless), copper, plastic, metal. Type of pipe used depends on the design of the heating system and is chosen for reasons of the given characteristics: hydraulic, operational, economic and environmental.

PEX Tubing can now be seen in any and every house hold and also in the commercial buildings. There are many reasons for which PEX Tubing has become the hot favorite choice of many. The PEX material is referred to the cross linked polyethylene molecules which result in a very strong, durable and flexible material which is apt for the purpose of plumbing. The PEX Tubing also has the capability to withstand extreme temperature conditions without getting damaged. One should be well versed with the installation schemes of the PEX plumbing systems as one would either require at some point of time to replace or repair the plumbing system of the house. As today people are mostly using PEX Tubing it is advised to be familiar with the PEX installation schemes.

There are basically five different installation schemes. The first installation scheme is the Trunk and Branch Scheme. This is like the traditional copper pipe system. There is a main trunk line running through out which has small branches running out of the main trunk till the fixtures. The main difference between the PEX trunk and branch scheme with any other scheme is that there is no need of coupling fittings in this scheme. Moreover the PEX Tubing system has lesser chances of leakages as compared to the copper plumbing systems as the PEX pipes are more flexible in nature.

The fourth type of the installation scheme is the Structured Plumbing Scheme. In this scheme the heated water is redistributed to the fixtures in groups and the last scheme is the Modified Home Run scheme.

With the increase in the demand of the radiant floor heating systems in the market the demand of the PEX Tubing has also increased as these systems make use of the PEX Tubing only. The PEX Tubing has a very important role to play in these systems. The PEX tubing are the tubes made from cross linked polyethylene and makes sure that the rooms and the floors of the rooms are equally warm even if the temperature conditions outside the house are harsh and cold.

Generally the material of this PEX Tubing is very durable, robust and long lasting. It is also capable of withstanding high degrees of temperature.  Another reason for the recommendation of the PEX Tubing is that the better the quality of the pipe the better will be the heating and longer will be the duration for which the floor will remain warm. On the other hand the copper tubes are neither cost effective nor energy saving, rather the copper tubes very easily get corroded as well.  The PEX Tubing is free from any such problems and is the best available option these days.

There are also special pipes and PVC fittings that are designed to work in the heating of individual houses. For greater reliability of these products are reinforced with various materials. For example, PVC pipes and fittings are PVC, reinforced with fiberglass. This greatly increases their durability and reliability. The model can serve as a high-class polypropylene fittings BOW Group, long-lasting and trouble-free operation of heating homes and water.

Successfully used for rainwater drainage, sewage and soil water PVC pipes and PVC plastic fittings.

Buy PVC fittings and pipes should be remembered that by buying in bulk, you get a quality product that will benefit from the installation. And the price is much lower.
