Welding conditions for PE water supply pipes: The weld surface of PE water supply pipes must be clean and (clean) dry. Unclean welding surface will affect the melting and entanglement between molecules (molecules); PE water supply pipeline welding requires reasonable heating temperature and heating time to ensure sufficient viscous melt; appropriate external force (external force) will aggravate the deformation of molecules , so that the molecules are fully fused at the two welding surfaces. In order to ensure the production of PE gas pipe, coal mine units and departments at all levels pay great attention to the relevant research on gas gas. At present, the measures in coal mine production are to use special pipelines to drain gas to ensure the progress of mine operations. Gas pipelines are pipelines used in coal mines to discharge gas. The performance of gas pipes directly affects the production of coal mines; sufficient cooling time is required.
