According to experts' predictions, the overall heat trend of the PVC transparent pipe production line market is stable and upward. In the future PVC transparent pipe production line market, the development speed of PE pipe production lines will be higher than that of other PVC transparent pipe production lines. In the PVC transparent pipe production line industry proportion will gradually increase. 　　

In recent years, my country's plastic PE production pipeline has formed a huge industrial chain driven by high-tech drive and the application demand of pillar industries, from upstream raw and auxiliary materials industry and processing and testing equipment to downstream machinery, automobiles, motorcycles , household appliances, electronic communications, building materials and other major application industries, the development of plastic PVC transparent pipe production line is full of vitality. At the same time, industries such as construction, home appliances, and automobiles have high demand for plastics.

In order to ensure the welding quality of the PVC transparent pipe production line, the welding materials for the cladding layer and the base layer should be properly selected first. In order to prevent dilution and carbon migration more effectively, an isolation transition layer is welded between the base layer and the cladding layer, so the welding material for the isolation transition layer should also be selected. The basic principle of selecting welding materials is: the welding materials used for cladding should ensure that the content of the main alloying elements of the metal is not lower than the lower limit specified in the standard for the base metal of the cladding; There is a certain content of stabilizing elements such as Nb and Ti or C≤0.04%. For the base layer, the welding materials should be selected according to the alloy content of the base steel to ensure that the tensile strength of the welded joint is not lower than the lower limit of the tensile strength specified by the base metal standard for the base layer.
