PP pipe has strong corrosion resistance, good corrosion resistance to non-oxidizing acids (hydrochloric acid, dilute sulfuric acid, hydrofluoric acid, dilute nitric acid, alkali and salt solution), concentrated nitric acid, fuming sulfuric acid, chlorinated Acid and other strong oxidizing acids are excluded; PP pipe has high strength, excellent impact resistance and tensile strength; PP pipe has good temperature resistance, and can transport various corrosive media within 90 degrees Celsius; PP pipe is light in weight and easy to install and maintain ;Widely used in chemical, chemical fiber, chlor-alkali, dye, water supply and drainage, food, medicine, sewage treatment and other industries.
In order to achieve the ideal connectivity of PP pipeline engineering, it is necessary to use the hot air welding process. The hot air process is widely accepted by professionals in the industry because of its simple use, especially for PP pipe welding, which has unique advantages.
- The rapid hot air welding technology also uses the heated wind or air to preheat the welding rod and the corresponding parts of the base metal to be welded to achieve welding;
- During heating, part of the hot air heats the electrode at the bottom of the tuyere, and another part of the hot air is used to heat the area to be welded of the base metal;
- The process also includes five stages of surface treatment, heating, pressurization, diffusion between molecular chains and cooling, and the specific operation requirements of each stage are also related to the specific appearance shape and internal structure design of the parts to be welded.
