Welding process steps of PE water supply pipeline: According to the welding specification of PE water supply pipeline, select the welding mold and turn on the electric heating; according to the seasonal temperature change, the heating temperature will fluctuate or decrease (±10℃) on the original standard temperature, and the standard temperature is 220℃ ;Cut the end face of the PE water supply pipe so that the end face is perpendicular to the axis; the water supply pipe and fittings should retain proper interference, and the excess part should be used with a cutter; remove the dirt and other impurities on the outer and inner surfaces of the welding area of the water supply pipe and fittings; During the welding process, the insertion of the water supply pipe should not be too deep, which will cause blockage of the water supply pipe, which is not suitable for over-submersion, and the submersible welding may not be firm; insert the welded PE water supply pipe and pipe fittings into the heating mold at the same time to achieve After the heating time, pull out quickly and insert the welded end of the water supply pipe in the pipe fitting with uniform pressure (usually 2-3 Mpa). Push until the marked insertion into the pipe, in a very short time, allowing small range adjustments; depending on the specification of the PE water supply pipe, keep the welded state until the cooling time, generally ranging from 30 minutes to 50 minutes.
