1. Before the electric fusion socket connection, the two corresponding parts to be connected should be straightened so that they are on the same axis, and the mechanical heat fusion socket connection should be adopted. In recent years, hot-melt socket connections have been used less and less in urban water supply polyethylene pipe connections, but they are more commonly used in building water supply polyethylene pipe connections.
2. The connection end of the electrofusion socket connection pe pipe should be cut vertically, and the dirt on the pipe and fittings should be wiped off with a clean cotton cloth, and the insertion depth should be marked to remove the skin randomly;
3. When the electrofusion socket is connected to the pipeline, the voltage and heating time of the power supply should comply with the regulations of the pipeline manufacturer, and corresponding electrical protection measures should be provided according to the voltage and current intensity used and the characteristics of the power supply.
When polyethylene pipes or pipe fittings with similar melt flow rates to PE pipes are hot-melt butt-jointed, the heating temperature, welding pressure, and welding time should be adjusted, and tensile strength, hydrostatic strength, and blasting tests should be carried out to check that they meet the requirements. before use.
