| Polyethylene(PE) pipe is very good material for engineering, and it is wildly used for gas engineering. PE pipe is used for gas engineering so early overseas that urban gas pipeline network in many developed country is made up of PE pipes, which are developing in the trend of hypo-high pressure gas transmission system. These countries are extending the use of PE100, the fourth generation of PE product. Meanwhile, they have advanced and well-developed technology standard from manufacturing to application. Now our country is spreading the use of PE80 pipe, which is a faded product, as we do not have corresponding design, application&proof-test standard as well as our equipment and engineering technology are comparatively unenlightened. In comparison of PE pipe with steel pipe, It will be systematically analyzed the PE pipe engineering related issues in this thesis, including the economic features of PE engineering technology, application technology, choice of steel-plastic conversion & welding technology. On the basis of the mentioned analysis, I bring up with systematic measures for quality insurance of PE pipe engineering in frigid zone.PE gas pipeline engineering application technology is advanced and unique. We need complete measures to ensure the engineering quality. Human resource is the essential key in engineering quality control. He is not only technician and operator, but also a developer, deviser, custodian, intendance&checker. We should normalize the operations, enhance the management of material and equipment, strengthen the control of engineering process, application&proof-test on people-oriented basis so as to ensure PE gas pipeline engineering quality from all aspects.
