PE gas pipe and PE water supply pipe belong to PE pipe. PE is also called polyethylene. In the world, polyethylene pipes are divided into five grades: PE32, PE40, PE63, PE80 and PE100. The materials used for polyethylene water supply pipes and polyethylene gas pipes are mainly PE80 and PE100, which are difficult to use, but It also brings many hidden dangers to the use of PE pipes.
Therefore, the National Bureau of Standards has made a lot of amendments to the new standard GB/T13663-2000, stipulating that the different grades of PE80 and PE100 of the water supply pipeline correspond to different pressure strengths, canceling the tensile strength performance in the old standard, and increasing the elongation at break. (Greater than 350%), which emphasizes the basic toughness.
The domestic production of this production line is mainly based on PE100 raw materials. This is mainly because of technological progress in recent years. The raw material price of PE100 is almost the same as that of PE80. However, in terms of performance, PE100 is definitely better than PE80 raw materials. In addition, PE water supply pipes and PE gas pipe extrusion line equipment have been continuously improved, and PE pipes have reached the international first-class level.
