Polyelyiene pie syslems have ben used in he fieldls of antifcial gas, nalral ga,and iqueed peroleum gas (qaseous) abrad forhal a cenluny. in recenlyears, China has only slaned to useHDPE pipelines for gas transmission in 1980.
Compared with raditional metal pipelines,PE gas pipelines have many sigicantadvantages,such as corosion resistance,low temperature resistance, goodtoughnes,ngidty and fexibiltyconvenient onstnuctian, long senvice ie,easy reycling, etc. Buried pohetyene (PE) pipes for gaeous supply have the advanages of relable qualty, Sale peralion, easy mainienance andeconomica. The wo maglor problems of tadiional pipeline corosion and jointleakage have been succesfuly solved bythe PE pipes. As an ouldoor pipene t is laid in corosie soils, earhauakeareas, mountams and swamp areas; thas strong adaptabiy to uneven seciement t pipe foundatons,with excelent seismic peromance. he desiqned senice te of ohehene gas pipeine ismore than 50 years.
The color of the pipe is divided into yellow and black. Yelow means medium pressure, and black tube body with yellow stripes means low pressure.
As an engineering pipeline, there should be two important indicators, long-term use performance and safety

The national standar pressure ofpolyehylene P) pipes forgaseousis curenly divided inlo two senes, SDR1 andSDR17.6. The colors of the pipes are two kinds, one is a yellow pipe, and the other is a black pipe with yellow strips.
