Reasons for poor welding of PE water supply pipelines: The quality of water supply pipelines is not good. In order to reduce costs, many manufacturers use recycled materials or production process problems, resulting in unqualified quality and difficulty in welding; whether it is the same brand of PE water supply welded pipes, due to different brands The raw materials and processes of the water supply pipes are different, and the fusion crystalline molecules are not easy to combine, resulting in poor welding. PE power pipe adopts PE (modified polyethylene) for hot dipping or epoxy resin for inner and outer coating, which has excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not cause galvanic corrosion. Low water absorption, high mechanical strength and small friction coefficient, which can achieve the purpose of long-term use. It can also effectively damage plant roots and soil environmental stress; whether the welding temperature meets the requirements, whether the temperature is adjusted due to seasonal changes, whether the temperature of the welding machine meets the standard, and temperature is an important factor affecting the welding stability of PE water supply pipes. PE water supply pipe is widely used in the field of water supply pipe manufacturing due to its 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; the PE water supply pipe is squeezed by external force during the welding process, which causes the water supply pipe to be out of round, cannot be tightly combined, and is difficult to observe with the naked eye, resulting in weak virtual welding; PE water supply Whether the welding of the pipeline is firm is related to many factors. The material of the water supply pipeline, whether the rust is removed before welding, whether the welding material is correct, what welding method is used, argon arc welding, handle welding, gas welding or oxygen welding are the main factors that cause poor welding.
