There are many classification methods for hdpe pipe. According to the application field, it can be divided into HDPE Water Supply Pipe, gas pipe, aluminum-plastic composite pipe, buried drainage pipe, agricultural irrigation pipe and electrical casing: it can be divided into pressure pipe and non-pressure pipe according to pressure. Water supply pipes and gas pipes belong to the category of pressure pipes.
In recent years, the density alone has not been able to accurately reflect the essential properties of PE as a pipe. At present, the internationally accepted classification method is to classify pipes and their raw materials according to the long-term hydrostatic strength of PE pipes, and is divided into PE 32, PE 40, and PE 63. PE 80, PE100. PE 80 and PE 100 pipes can be used to transport gas, while pipes below PE 63 are mainly used for hot water pipes and sewage, HDPE Irrigation Pipe, etc.
