The construction technology of polyethylene tape in the gas pipeline
< br />
PE gas pipeline construction is to follow the polyethylene tape gas pipeline engineering technical regulation ( CJJ63 - 95). And the town gas pipeline engineering construction and acceptance specification) ) ( CJJ33 - 89). 。 PE pipe operation and low maintenance cost and can save pipeline anticorrosion link in the installation work, and other seamless steel pipe, welded steel pipe and cast iron pipe and other metal pipes, compared with high efficiency. Suitable conditions of PE pipe 2 PE pipe has good flexibility, coiled tubing can volume, which can reduce the number of joints in pipe network, can be zoomed laid, easily around obstructions, to further reduce the number of joint. PE pipe is a thermoplastic material, can be repeatedly processing forming, make the hot melt and fused connection possible. PE pipe impact resistant performance is good, has the high fracture elongation, experience proved resistant to the effects of earthquakes and other natural disasters. PE pipe has good air tightness, gas permeability is low.
