Product Details


Reducer is a kind of pipe fitting for pipe diameter. Usually, the forming process is shrinkage pressing, expanding pressing or shrinkage and expanding pressing. For some specifications of different diameter pipes, stamping can also be used.

Shrinkage / expanding forming

The shrinkage forming technology of large and small head is that the tube blank with the same diameter as the big and small head is put into the forming die, and the metal moves along the cavity and shrinks to form by pressing along the axial direction of the tube blank. According to the diameter of the reducer, it is divided into one pressing or multiple pressing forming.

Stamping forming

In addition to the use of steel pipes as raw materials for the production of large and small head, some specifications of the size of the head can also be used for the production of sheet metal stamping process. The drawing die is designed according to the inner surface dimension of the big and small head, and the blanked steel sheet is stamped and drawn by the stamping die.Dry cloth is used to wipe the socket side and the outside of the socket before the big and small heads are bonded. Acetone is used to wipe clean the socket when the surface is greasy.
