In the 1940's, once introduced, PE pipes for its outstanding performance and economic rapid promotion, after 60 years of development, polyethylene pipe has become the use of excellent performance, design theory, perfect products and complete in production and life of a kind of indispensable plastic piping. Polyethylene (PE), the application of pipeline for society and the enterprise to bring good economic, social and environmental benefits. Especially in gas transmission and distribution field, PE gas pipe more show its incomparable advantage. 1 and physical properties PE pipe between high performance of fuel gas, the density polyethylene, maintain betwein between the high density polyethylene rigidity, and has good flexibilflexibilitexibility, non-absorbent, avirulent insipidity, excellent electrical insulation and under normal temperature good acid, alkali, salt and organic solvents, cold resistance, good resistancesistance to creep properties. And more excellent than the HDPE melt connection properties of plastic pipe installation, benefit. 2,br>2, long use value PE gas pipe, corrosion resistanresistance, long life buried tube in - 60 degrees - 60 degrees Celsius temperature range safe use of 50 years. 3, large conveying flow PE gas pipe wall, can enhance the smooth, increase the flow velocity of medium, compared with the same metal pipe, conveying bigger flow, save power consumption. 4 and convenient construction PE pipe light quality, gas density for steel 1/8, easy handling, flexible, simple, welding, need not roadway anticorrosive processing, construction speed is quick. 5, excellent resistance to stress cracking PE pigt;PE pipe stress cracking gas pipe, superior in engineering application can greatly reduce the pipeline leak and tube, increase the safety of gas transmission. 6 and incomparable flexibility PE pipe gas excellent flexibility, when the ground subsidence or when the earthquake happened, to a certain degree of deformation produced without fracture, avoid gas leak. But contrary to occur, steel, will cause gas leak, or gas explosion occurred. In the 1940's, once introduced, PE pipes for its outstanding performance and economic rapid promotion, after 60 years of development, has become the PE gas pipe using superior properties, design theory, perfect products and complete in production and life of a kind of indispensable plastic piping. Polyethylene (PE), the application of pipeline for society and the enterprise to bring good economic, social and environmental benefits. Especially in gas transmission and distribution field, PE gas pipe more show its incomparable advantage. Fried events. Update Date:2010/6/10 3:10:31
