Applications of PE pipe: PE pipe full name of HDPE high density polyethylene pipe, compared with traditional metal pipe and other plastic pipe, with low density, strength and quality is high and the temperature of brittle to low, toughness, corrosion resistance is good insulation properties , easy to color, such as construction and easy to install, which is widely used in municipal and construction drainage, gas, heating system, wire and cable threading, agricultural water-saving irrigation and industrial sewage, mining, transportation and other minerals. Compared with steel, the cost can be reduced by about 12%, long working life, can reach 50a (steel generally 20a), and low maintenance costs. In developed countries and regions abroad, PE pipes are intercity buried gas pipeline occupancy reached 90% market share in the supply pipe up to 60%, and in terms of foreign PE pipe recalled by established a very mature standard construction specifications.
