High pressure thick wall elbow

The process of reducing the diameter of high pressure thick wall elbow is mainly to put the tube blank with the same diameter at the big end of the high pressure thick wall elbow into its forming die with excellent effect. In the process of use, the high pressure thick wall elbow will make the metal move along the die cavity and shrink to form through its pressing along the axial direction of the tube blank

High pressure thick wall elbow with excellent effect can be divided into one press forming or multiple press forming according to the size of its reducing pipe. The expanding forming of the product is mainly to use the tube blank with the diameter smaller than the big end of the reducing pipe, which uses the internal punching film to expand along the inner diameter of the tube blank

The expanding process of high pressure thick wall elbow is mainly to solve the problem that the reducing pipe with large reducing diameter is not easy to be formed through its reducing diameter during use. Sometimes, it is necessary to combine the expanding and reducing methods according to the needs of its materials and product formation

In the process of deformation and pressing for expanding and reducing the diameter of high-pressure thick wall elbows, the products with excellent effect can be determined to use cold pressing or hot pressing according to their different materials and reducing conditions. Generally, cold pressing is required as much as possible

After many times of reducing, the high pressure thick wall elbow will directly cause serious work hardening. The good or bad surface treatment of the high pressure thick wall elbow will directly affect the service life of its performance stability layer to a certain extent. The coating varieties are different, and the coating quality is good or bad

The construction of high-pressure thick wall elbows and other factors also determine the life of the performance stability layer to a certain extent, so the treatment of the appearance of high-pressure thick wall elbows should be strict. It is required to implement those with excellent performance according to the standards of its performance stability layer, and its methods need to be constantly explored and summarized
