PE pipes are widely used. Water supply pipe and gas pipe are its two largest application markets. PE resin is polymerized from monomer ethylene. Due to different polymerization conditions such as pressure and temperature during polymerization, different density resins can be obtained. Therefore, there are high-density polyethylene, medium density polyethylene and low-density polyethylene. When processing different types of PE pipes, according to the different application conditions, different resin grades are selected, and the requirements for extruders and molds are also different.

In the world, the materials of polyethylene pipes are divided into five grades: PE32, PE40, PE63, PE80 and PE100. The materials used for gas pipes and water supply pipes are mainly PE80 and PE100. In China, there is no classification for the special materials for polyethylene pipes, which makes it difficult for domestic polyethylene gas pipe and water supply pipe manufacturers to select raw materials, and also brings considerable hidden dangers to the use of polyethylene pipes.
