Experience with similar utilities showed the best side polymers and great advantages over traditional metal. July 10, 1996 The Ministry of Construction of the USA adopted a decree № 12 “On the extension of the scope of plastics piping systems engineering.” This helped the transition of production water and waste-water systems to a new level that meet the needs of our time in clean, easy to assemble and durable systems.
High chemical resistance (pipes of Polypropylene resistant to most acids, alkalis, salt solutions and water-soluble organic compounds, but not resistant to the action of aromatic and chlorinated hydrocarbons).
The absence of galvanic corrosion.
Durability (service life of pipes 50 years).
Resistance to a draft of the stone and pollution.
Low resistance current of water.
Ease of installation and safety.
Cheapness compared with metals.
All these features of PEX plumbing pipes make them indispensable in the construction of engineering structures.
Energy Trust, involves a substantial increase in housing construction, special attention is paid to the use of new technologies in construction engineering of building services.
Decisions adopted at the state level, combined with evolving market relations, creates opportunities to increase use in new construction and major repairs of the existing housing stock and industrial pipes from more durable plastics.
The widespread use of plastics pipes in new construction and repair of worn-out pipelines is predetermined by their benefits, which are manifested at all stages: during production, installation and operation. Because of its light weight of PEX plumbing pipes in combination with their flexibility and ease of machining, as well as speed and reliability of the compounds significantly reduced labor costs and create greater ease in carrying out construction works. Labor costs and, importantly, the time of installation of PEX plumbing pipe compared to the metal lower in the 3-5 times per meter PEX plumbing pipe 10 times lighter than steel, which gives a significant reduction in transport costs.

Design features of the materials allows us to combine metal and PEX plumbing piping, which is important when undertaking renovations. The cost of ready-to-launch pipeline, taking into account the cost of materials is 1.5-2 times lower than that of metal piping. The service life of PEX plumbing pipes without major repairs for over 50 years, the pipes do not corrode, is not formed within the scale. PEX plumbing pipe material does not contain any harmful substances and is completely safe for humans. One of the advantages of PEX plumbing pipe compared to metal is that the freezing of water in the pipeline (due to its elastic properties) is not destroyed. Tests have confirmed the high strength characteristics of PEX plumbing pipes and showed high reliability of the new material. “
