Advantages of PEX pipes also include reliability
PEX tubing have a capacity of 25-30% higher than that of steel due to smooth inner surface and the lack of domestic deposits. Inner diameter steel pipe decreases with time due to corrosion fouling. Same diameter polyethylene pipe increases during operation without loss of efficiency due to the phenomenon typical of polyethylene creep. This increase is about 1.5% over the first 10 years and about 3% over the life of the pipeline. Consequently, the inner surface of polyethylene pipe with time becomes more soft and smooth, which improves the flow wall polyethylene pipe and reduces the resistance to movement.

The advantages of PEX pipe also include reliability, durability and low maintenance. The service life of steel underground piping is no more than 25 years. Whereas the life of PEX pipes – at least 50 years. For polyethylene pipe is not needed electrochemical protection, which creates additional savings in the construction and operation of the pipeline. These tubes can be operated at temperatures ranging from -50 ° C to + 60 ° C.
