Pipes

So, for pipe sizes 40 and 50 mm wall thickness of 1.8 mm, and the pipe diameter 110 mm – 2.7 mm vs. 3.2 mm in PVC pipe regardless of diameter. While maintaining the necessary mechanical rigidity polypropylene tubes. As a result – reducing the cost of polypropylene tubes compared to pipes made of PVC with equal functionality. Polypropylene is characterized by greater shock resistance as compared with polyethylene and PVC pipes so much "easier" tolerate difficult conditions of transportation and installation.

The prevalence of plastic pipes in cold water all in Russia in 2006, it produced 87.74 tons of plastic pipes for cold water. The overwhelming volume of plastic pipes for cold Water pipes are made of PE – 86.8%. The largest part of polyethylene pipes for cold water use in external systems (street, mezhkvartalnye Network) – 85.2%. And 14.8% of polyethylene pipes for cold Water used in interior decoration of residential and nonresidential. There must be clear that the weight of 1 lm polyethylene pipe for cold water in the outer lining of significantly weight exceeds 1 rm polyethylene pipes for the internal wiring used by the difference of diameters used in the external water supply pipes of large diameter than the inner. Thus, this dominance external networks in the consumption of polyethylene pipes for cold water in tonnage terms, is relative. The main applications of PP pipes for cold water supply – internal wiring inside residential and nonresidential use.

Pipe PP – an expensive raw material for large diameter pipes for external water systems. This is one of the main reasons for its widespread use in internal networks supply houses. PVC pipes for cold water, in turn, prefer to mount as an external water supply systems: 93.8% are external water supply and 6.2% – on the inside. With the current situation and outlook for the Russian market of plastic pipes for cold water can be found in the report of the Academy of IKAR industrial markets "The market of plastic pipes for cold water supply in Russia."
