How do you make a reducer?

- May 19, 2020-

Reducer is one of pipe fittings, which is used to connect two pipes of different diameter by their ends. According to the different shape, it is divided into concentric reducer and eccentric reducer. Based on the material,there are many kinds of reducer, like stainless steel reducer (304, 316, etc.), alloy steel, carbon steel reducer (A106B, 20, Q235B, Q345B, 16Mn, etc.).The largest production base is in northern China.

Then how do you make a reducer? Usually the forming process is to reduce the diameter of pressing, expanding the diameter of pressing or reducing the diameter plus expanding the diameter of pressing. For some specifications, it can also be made by punching forming.

1. The shrinkage forming process is to put the tube blank with the same diameter, into a forming mould. Pressed along the axial direction of the tube blank, the metal raw material moves along the mould cavity and contracts to take shape. Specified by the size requirement, it can be divided into one pressing forming or multiple pressing forming. In addition, the tube blank can be both seamless and welded.

2. Punching forming is a process in addition to the process which uses steel pipe as raw material. For certain specifications, the reducer can also made by steel plate, through the punching process.The shape of the mould used for drawing is designed according to the size of the reducer’s inner surface. Blank steel sheet is formed by punching and drawing with the mould.
