Description

technical field [0001] The invention relates to the technical field of gas pipeline materials, in particular to an impact-resistant and crack-resistant material for gas pipelines. Background technique [0002] With the rapid development of urban economy, urban natural gas industry is also developing at a high speed, so higher requirements are put forward for the quality of natural gas pipelines. At present, polyethylene plastic pipes are widely used. Compared with other pipes, polyethylene plastic pipes have many advantages such as light weight, corrosion resistance, no rust, convenient laying, fast and reliable connection, and long service life. However, with the gradual increase in the design pressure of urban natural gas pipelines, especially the upstream long-distance gas pipelines are laid in cities, the problems of insufficient pressure bearing capacity and easy cracking of polyethylene plastic pipes are becoming more and more obvious. Therefore, it is urgent to explo...
