Polishing Sanitary Concentric Reducer For Seamless Pipe Fittings Technics Forged

Steel reducer is one of the chemical pipe fittings, used for two different diameter of the connection. Is divided into concentric reducer and eccentric reducer. Product material can be according to the 321, 304, 304 L, 310S , 316, 316L organize production, can also according to user specified criteria, material production, the production range from DN10-DN1200 (1/2 "to 48"), complete specifications.

A. Reducing/expanding forming

The process of reducing the diameter of the large and small ends is to place a tube blank with the same diameter as the large and small ends into a forming die, and press the tube blank in the axial direction to make the metal move along the mold cavity and shrink into shape. According to the size of the reducer, it can be divided into one press forming or multiple press forming.

B. Stamping

In addition to using steel pipes as raw materials to produce large and small ends, some specifications of large and small ends can also be produced using a stamping forming process using steel plates. The shape of the stamping die used for stretching is designed with reference to the inner surface dimensions of the reducer, and the blanking steel plate is stamped and stretched with the stamping die to form.
