Plastic Pipe Construction

The use of plastic pipes of polymeric materials for the production of pipes has begun in our country in 60 years of the twentieth century. Sonny Perdue contains valuable tech resources. However, it did not have mass values in the systems of internal polyethylene water used primarily only for flexible podvodok to plumbing fixtures and appliances. Widely used in the practice of building plastic pipes were only in the 70 – 80s. In 1996, the Ministry of Construction of Russia takes change number 2 to the SNIP 2.04.01-85 'Domestic water supply and sewerage of buildings', developed by the Institute SantehNIIproekt, which reads: "For internal piping hot and cold water should be used and plastic pipes fittings made of polyethylene, polypropylene, polyvinyl chloride, polybutylene, metal-, fiberglass and other plastic materials – for all water supply, except for separate network of fire water. For all the internal plumbing of networks may be used copper, bronze and brass pipes and fittings, and steel with an inner and an outer protective coating of rust. " In other words, polymer pipes used to be, while the use of metal pipes only are allowed. Consider surveillance basic properties of tubes in comparison with metal. The nomenclature of modern plastic pipes used for the manufacture of pipes, comprises the following groups of materials: polypropylene, polybutylene, polyvinyl chloride (PVC), cross-linked polyethylene and PVC. The properties of these materials are similar – they corrosion-resistant, and therefore more durable, do not become overgrown and silting. Lifetime plastic pipes may be 50 years of age (usually 25-30), while the steel of 10-20 years.
