Reducer is a kind of pipe fitting used for pipe diameter. The commonly used forming process is reduced diameter pressing, expanded diameter pressing or reduced diameter plus expanded diameter pressing. Stamping can also be used for reducing pipes of some specifications.

a. Reducing / expanding forming

The diameter reduction forming process of large and small head is to put the tube blank with the same diameter as the large end of large and small head into the forming die, and press along the axial direction of the tube blank to make the metal move and shrink along the die cavity. According to the size of reducing pipe, it can be divided into one-time pressing forming or multiple pressing forming.

b. Stamping forming

In addition to using steel pipe as raw material to produce large and small heads, large and small heads of some specifications can also be produced by steel plate stamping process. The shape of the die used for drawing is designed according to the size of the inner surface of the large and small head, and the blanking steel plate is stamped and stretched by the die.
