The buried polyethylene PE pipeline for polyethylene PE gas pipe has a very strong adaptability to uneven settlement of the pipe foundation and has strong wear resistance. It can be used in a variety of excavation-free ways, which greatly facilitates the construction and installation of the system, and the system cost is low. The maintenance cost is low and the engineering cost can be greatly reduced.
The production and inspection of buried polyethylene pipes for gas use are organized according to the requirements of the new national standard GB / 15558.1-2015 < Gas buried polyethylene pipes >. The polyethylene (PE) gas pipes produced by our company can be divided into four series according to their wall thickness.
Conventional gas pipelines, such as steel pipes and cast iron pipes, are mainly affected by corrosion and leakage of joints in the service life. High density polyethylene gas pipeline (HDPE gas pipe) has many outstanding characteristics, such as corrosion resistance, low temperature resistance, good toughness, safety and reliability of joint connection, which satisfactorily solves the two major problems of corrosion and joint leakage of traditional pipeline. In the field of gas transmission and distribution, polyethylene pipe (polythylene pipe) is widely used in the world.
In the world, polyethylene pipe (polythylene pipe) is divided into five grades, PE32P40, PE63P80 and PE100, while PE80 and PE100 are mainly used for gas pipe and water supply pipe. There is no classification of the special material for polyethylene pipe in China, which makes it difficult for domestic producers of polyethylene gas pipe and water supply pipe to select raw materials, and also brings great hidden trouble to the use of polyethylene pipe.
