Sometimes ready-made pipes and fittings after production need additional operations, such as installation, bending, welding, bonding or assembly. For example, pipes for sewerage to be uncovered, and then insert the funnel seal - rubber ring. Sometimes, especially complex fittings are manufactured by welding or gluing of several intermediates. In this case, use the contact welding, friction welding, rod, hot gas.
Despite the lack of proper raw material base in USA and Canada there are already dozens of companies manufacturers of plastic pipes made of different materials. If desired, it is easy to buy and import counterparts, since the market is working a lot of companies that sell plastic pipe systems from various manufacturers. Thus, the purchase of PEX plastic systems in today's realities - a nice choice between quality and cheap imports, but it is for a correct domestic products.

Currently, only a relatively small number of design companies really owns the design of the methodological apparatus of modern plastic pipes (a pipe made of polypropylene, polyethylene, metal and plastic). As a result, most project pipeline systems is performed in a very, generally, and construction organizations in the future have to make the executive scheme is based on his vision and experience. To this we must add that the vast majority of plastic piping installers actually mastered the technology of assembling their own. Characteristics of various pipes and installation of the nuances are often not present. It is known, for example, that the pipes of crosslinked polyethylene has a coefficient of thermal linear expansion at a temperature of 70-90 ° C is 7 times greater than, for example, metal-pipe of the same material. For this reason, they should be run secretly (in Stroebe, for baseboards, gypsum plasterboard, suspended ceilings, etc.). Polyethylene pipes are mounted at temperatures of 0-20 ° C, with their open-laying, when they are flowing coolant at a temperature above 70 ° C, are intricate sinusoid. A similar pattern will occur in cases where, for example, to save, rather than a stable reinforced polypropylene tube, which allows not only hidden, but open and the gasket in hot water systems use common polypropylene tube that has a 5 times larger than the coefficient of linear thermal expansion. All this not only spoils the aesthetic perception of prospective plastic piping, but often closes the road to their broad practical application. However, Russia already operates a number of major companies that can comprehensively and at the advanced level to solve all the problems of water and heat applied to objects of any purpose and any difficulty using the best plastic pipes. Maybe this will pave the way for promising new materials and technologies.

In addition, there are cases where the production of PEX pipes and other plumbing needs in order to reduce the cost of production of the raw material is added to a secondary polypropylene (in several american cities now take it to recycling collection points). This leads to a sharp decrease in the life of the tubes. Unfortunately, the domestic polypropylene pipes are still at the level of low quality. The addition of recycled materials in the primary raw material is a very dangerous symptom. Indeed, it is clearly leads to rapid polymerization of tubes: they may start to deteriorate even before the metal pipes, just as it did earlier in the destruction of low-quality braided wiring. All of this may actually lead to the discrediting of the idea of ​​plastic piping. Many manufacturers of PEX plastic pipes have a limited range of products, especially fittings - plastic fittings. As a result, installers are forced to purchase pipe some manufacturers, molded connections - others, and often several, and mounting hardware - the third. It is clear that rely on the perfect outcome in these conditions is not necessary. For polypropylene pipes, exactly as it is for all PEX pipes, this mix is ​​dangerous. When using the materials, in general, different modes of diffusion alloying to achieve a fully homogeneous (homogeneous), and therefore long-lasting connection is problematic. Similar problems can occur in cases where pipelines and other equipment manufacturers have very limited range of products. In this situation the installation companies are forced to go into different combinations and not justified by the replacement, that is, in fact, to take risks during the design and installation.

Connection technology of polypropylene pipes - the diffusion alloying. Manufacturers offer a wide range of pipes from 16 mm to 160 mm., With respect to the systems of cold and hot water and heating systems, including the floor.

Positive features and advantages of PEX plastic pipes are well known. On the disadvantages of these tubes is much less known, especially since many of them appear only in the domestic market, reflecting our specificity. Consistently analyze these shortcomings.

At the production stage. The vast number of Western and some Turkish producers of polypropylene pipes running on the system of Western standards, is a multistage and highly, advanced system of quality control. Such a system includes quality control, as the raw material and production technology. In particular, the production process on a mandatory basis by automatic control of the geometry and thickness of pipes, fittings as well as geometry. This ensures compatibility of all connections. However, such control is absent in the majority of small, artisan Turkish companies and, unfortunately, the domestic manufacturers, which does not give full confidence in the reliability of the connections of such pipelines. The manufacturing process for the production of high quality polypropylene tubes must meet a number of international standards such as ISO 9002.

It's something that is worth to change the ingrained idea that the radiator - it is the only source of warmth and comfort. Imagine that the heating season has ended or has not started yet, we have to dress warmly, muffle up in a rug, do not allow children to play on the floor. We offer you a profitable and independent system of water tubing, PEX water line, which you decide when your home should be warm or cool! As people feel more comfortable in cool air at the head and warm his feet, PEX heating is a system of perfect uniform heat distribution.

The use of indoor heating flat surfaces, devoting a considerable amount of heat radiation, no matter where they are located, will always create a more favorable climate than heating rooms purely convective devices. PEX tubing water will allow you to adjust the temperature of each room as needed that would prevent the cold and overheated areas, such as for heating radiators (convectors, air systems). Probably all know the feeling of reluctance to get up on a winter morning, knowing that the apartment cool during the night, because at night in winter the temperature outside drops sometimes to 10 degrees. In our system, Radiant Floor, you can set temperature day and night, at the same time, the temperature will always be automatically supported by modern sensors, which are installed on each site. However, due to low temperature heating surface, is only 22-26 ° C, very limited air circulation, which noticeably reduces the amount of dust rising.

 This is a scientific-technical and engineering approach.

   In this chapter we are interested in answer to the possible application of Radiant Floor coating and finishing "at the household level, not delving into the complexity of the physical and thermal calculations and tasks.

   Ceramic tiles (thickness 30 mm) is in all respects an ideal material in combination with the PEX Tubing tools: good heat conductivity, temperature resistance and mechanical resistance, durability, etc.

   Linoleum (plain or with various kinds of thermal insulating subbase) is rarely used in modern construction, however, by its heat-conducting qualities and blends perfectly with PEX Tubing heating Systems.

   Laminate flooring is widely used in modern country and cottage construction, ideally combined with the floor system, especially in light  (wood and polystyrene) systems, Radiant Floor Wisbro PEX.

   The greatest number of questions from experts and consumers is the system's compatibility Radiant floor and parquet.

   The Association of European manufacturers of wood coatings spent many years testing and has released a manual with theory, facts, and recommendations on the application of wood coatings with underfloor heating . With the permission of the Association we are given some data in this chapter.

Finish coating is an important participant in the process of heat transfer from the heating panels to the surrounding air, because has a thermal resistance, which depends on the material and thickness of its manufacture.

In addition, first, to sanitary and building codes may be restrictions on the maximum temperature of the floor surface, and secondly, the temperature of the floor surface is a calculated value that depends on the heat, the load on the heating system and the type (temperature) of the premises. Ie the final decision on the possible use of a finish coating made by the designer on the basis of many factors during the design of outdoor heating systems PEX Tubing heating.

The first attempt to create PEX took place in 1950, when scientists were looking for a way to straighten up the polymer material. Later on, the first method for obtaining PEX supply was created by using peroxide atoms. This method is also known as PEX-a. In 1970 the PEX pipe supply was already made for sale in Europe and in 1980 it reached the US.

PEX polymer was later created by the so called PEX-b method using silane particles. PEX-a and PEX-b methods are only different within manufacturing methods, but the quality of the material is mainly the same. PEX-c is the ecological version of PEX tubing  that uses no other atoms and no heat to create bonds between atoms, but an electron ray which stimulates the particles to get close to one another and form unbreakable chains.

The categories are known as A, B and C for PEX standards in Europe. The quality is not a reference is this case, but only as in ecological environmental protection. Many manufacturers that use method C to obtain polymer have to raise prices in comparing to the previous two methods, only because the electron ray devices cost a lot of money.

In America, the standards are different, and are all wring down on a list on the item. The polymer product bought will have a serial number and also an identification number for showing it to what it is supposed to be used. Some of the polymer pipes and tubes can be distinguished by colors, when it comes to pipes for hot or cold water, and even for electric cables tubing.

The performance test that every polymers item must pass is also a standard quality law. All polymer tubes or pipes must be CSA, ASTM and NSF approved and tested in order to get on the market and be sold to clients.
