Second, what is the material of pe gas pipe?
1, pe gas pipe is polymerized from monomer ethylene. Due to different polymerization conditions such as pressure and temperature, resins with different densities can be obtained, so there are differences among high density polyethylene, medium density polyethylene and low density polyethylene.
2. Internationally, the material of pe gas pipeline is divided into five grades: PE32, PE40, PE63, PE80 and PE 100. The main materials used for gas pipeline and water supply pipeline are PE80 and PE 100.
3. The special materials of 3.pe gas pipeline are not classified in China, which leads to the difficulties in the selection of raw materials for domestic polyethylene gas pipeline and water supply pipeline manufacturers, which also makes the use of polyethylene pipeline have certain hidden dangers.
Three, pe gas pipeline specifications and models
1, pe gas pipeline is divided into 32, 50, 63, 90, 1 10, 160, 200, 250, 3 15, 355, 400, 450.
2.pe gas pipelines are divided into two types: PE80 and PE 100. In terms of wall thickness, Dushrd 1 1 and zhiSDR 17.6 are often used.
3. The National Bureau of Standards has made a lot of modifications in the new GB/T 13663-2000 standard, and made new regulations for different grades of water supply pipes such as PE80 and PE 100, which cancelled the tensile strength performance in the old standard and increased the elongation at break.
The above is about the ranking of pe gas pipe manufacturers, pe gas pipe materials and pe gas pipe specifications and models. Thank you for reading. If you want to know more about pe gas pipes, please stay tuned.
