Pipe Fitting Reducer is a kind of pipe fitting used for pipe diameter. The commonly used forming process is reducing, expanding or reducing plus expanding, and stamping can also be used for reducing pipes of certain specifications.
A. Reducing/expanding forming
The reducing forming process of the pipe fitting reducer is to put the tube blank with the same diameter as the big end of the pipe fitting reducer into the forming die. By pressing along the axial direction of the tube blank, the metal moves along the die cavity and shrinks to form. According to the size of pipe reducer, it can be divided into one press forming or multiple press forming.
B. Stamping forming
In addition to using steel pipes as raw materials to produce pipe fitting reducers, the reducers of some specifications can also be produced by using the steel plate stamping process. The shape of the die used for drawing is designed according to the size of the inner surface of the pipe reducer, and the blanking steel plate is punched and stretched with the die.
