Chemical pipe fittings are used for the connection between two pipes of different diameters. According to the shape, it is divided into two types: concentric
steel reducer and eccentric steel reducer. Steel reducer materials include stainless steel reducer (304, 304l, 316, 316l), alloy steel reducer, carbon steel reducer, and steel reducer materials including No. 20 steel, Q235, Q345, 16Mn, etc.
Manufacture of steel reducer: steel reducer is a kind of pipe fitting used for pipe diameter. The commonly used forming process is reducing diameter pressing, expanding diameter pressing, or reducing diameter plus expanding diameter pressing, and stamping forming can also be used for reducing pipes of certain specifications.
1. Shrinking/expanding forming The shrinking forming process of the steel reducer is to put the tube blank with the same diameter as the large end of the steel reducer into the forming die, and press along the axial direction of the tube blank to make the metal move along the mold cavity and Shrink forming. According to the diameter of the reducer, it can be divided into one-time press forming or multiple press forming.
2. Stamping In addition to using steel pipes as raw materials to produce steel reducers, some specifications of steel reducers can also be produced by stamping steel plates. The shape of the die used for stretching is designed concerning the size of the inner surface of the steel reducer, and the blanked steel plate is stamped and stretched with the die.
