SCH STD Concentric Eccentric Reducer Seamless Pipe Fittings

Product Description

The reducer is a pipe fitting used for the diameter of the pipe. 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 diameter pipes of certain specifications.

a. Diameter reduction/diameter expansion forming
The diameter reduction forming process of the small and small heads is to put a tube blank with the same diameter as the large end of the small and small heads into a forming die, and press the tube in the axial direction to make the metal move along the mold cavity and shrink into shape. According to the size of the reduced diameter of the reducer, it is divided into one-time press forming or multiple press forming.

b. Stamping and forming
In addition to the use of steel pipes as raw materials to produce the small and small heads, some specifications of the small and small heads can also be produced by the stamping process of steel plates. The shape of the punch used for drawing is designed with reference to the size of the inner surface of the size head, and the blanked steel plate is punched and stretched with the punch.
