PP pipe has the characteristics of good heat setting, high temperature resistance, good chemical resistance, creep resistance, high tension, good insulation, insoluble in organic solvents, non-drying, and non-toxic. Suitable for chemical factories, electronic semiconductor factories, pharmaceutical factories, sewage treatment plants and other industries. It has been widely used in high acid and alkali chemical product transportation system, pure water transportation system, drinking water transportation system, sewage and wastewater transportation system, environmental engineering and general pipeline system, telecommunication optical cable transmission and distribution pipeline system. The PP pipe is placed on the operation frame, one side is leaning against the welding surface, and the hydraulic clamp is advanced to make the pressure reach the required welding pressure.
The safety and durability of PP pipe means that there will be no life-threatening and family safety-threatening events such as water leakage and bursting during its service life, and it can ensure long-term use. This requires PP pipes to be resistant to corrosion, high temperature, and frost. Mechanical behavior. Plastic pipes have poor high temperature resistance, and are prone to deformation and leakage when the temperature difference is large, and their compressive capacity is small and easy to brittle. . PP pipe adopts welding technology in construction, so it is also commonly known as hot melt pipe. PP pipe has the characteristics of non-toxic, light weight, pressure resistance and corrosion resistance.
Any kind of process method has its own processing characteristics, and therefore its application scope also has certain limitations. PP pipe round pipe is widely used in industrial production. Bending is a commonly used pipe bending method. It is divided into two types: manual pipe bending and pipe bending machine bending. The blank is bent. According to whether the pipe is heated or not, it can be divided into two types: cold bending and hot bending. PP pipes are generally small-diameter tube blanks. Due to the small bending moment, cold bending is used, and hot bending is often used. Manual bending does not require special bending equipment.
PP pipe is only suitable for single-piece small batch production occasions without pipe bending equipment, pipe bending machine bending is carried out on a vertical or horizontal pipe bending machine. PP pipe is divided into hot and cold water pipes, mainly used in civil water supply. Use a special cutter for cutting the pipe to cut the pipe according to the required size. When cutting the pipe, be careful not to run off the line, and slowly rotate the blade. Do not advance too sharply, which will damage the blade. When the cutter is difficult to rotate, the cutter should be rotated in the opposite direction, the blade should be removed, and the line should be re-run. When the required pressure is not reached, loosen the heating pressure relief valve to make the pressure gauge display drop to zero, re-adjust the hydraulic regulating valve, and then lock the heating pressure relief valve until the pressure is expressed to the required pressure.
