The hot melt welding of PE water supply pipes should use the same grade, the same specification, and the same pipe material. Similar performance, different PE water supply pipeline welding test and verification; when making PE water supply pipeline hot melt connection in cold weather (less than -5°C) and windy weather, it is necessary to take protective measures to protect or adjust the welding process ; It is strictly forbidden to carry out hot fusion welding in rainy days, and the water inlet of the welded joint may easily cause the virtual welding of the PE water supply pipeline; PE water supply pipes are widely used in the field of water supply pipe manufacturing due to their high strength, corrosion resistance, and other characteristics. Because it will not rust, it is an ideal pipe material to replace ordinary iron water supply pipes. It is mainly used in the fields of urban water supply, urban gas supply and farmland irrigation.
