Welding process of PE water supply pipeline: The temperature change during the welding process of PE water supply pipeline has a great influence on the welding. When the temperature is lower, the heating time is prolonged and the temperature is raised. When the temperature is high, the heating time can be appropriately shortened, or the low temperature of the hot melt machine can be reduced. Pressure conversion: The actual welding pressure (pressure) is different from the process (process) parameters: first, convert the process pressure (pressure) (heating pressure, endothermic pressure, welding pressure) into hydraulic system pressure; The frictional resistance) is added to P1 to get the working pressure.
