Reasons for poor welding of PE water supply pipeline

1.The quality of water supply pipeline is not good, many manufacturers in order to reduce costs, the use of material or production process problems, resulting in unqualified quality, welding difficulties.

2. No matter the same brand of PE feedwater welding pipe, due to the different raw material formula and process of feedwater pipe production of different brands, the fusion crystallization molecules are not easy to combine, resulting in poor welding. pe power pipe using PE (modified polyethylene) for hot dip plastic or epoxy resin for internal and external coating products, has excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation, no electrical corrosion. Low water absorption, high mechanical strength, small friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent the damage of plant roots and soil environmental stress.

3. Whether the welding temperature meets the requirements, whether the temperature is adjusted due to seasonal changes, and whether the temperature of the welder meets the standards, temperature is an important factor affecting the welding stability of PEPE water supply pipeline. pe water supply pipe because of its high strength, corrosion resistance, non-toxic characteristics, is widely used in the field of water supply pipe manufacturing. Because it does not rust, it is an ideal pipe to replace ordinary iron water pipes. It is mainly used in urban water supply, urban gas supply and farmland irrigation.

4.in the welding process of additional external extrusion, resulting in the water supply pipeline is not round, can not be closely combined, difficult to naked eye observation, resulting in virtual welding is not firm.

Whether the welding of PE water supply pipeline is firm is related to many factors. The material of 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 causing poor welding.
