Reducing Shape 8'' X 4'' SCH40 ASME B16.9 Steel Pipe Reducer
Reducer, used for connection between two pipes of different diameters. According to different shapes, it can be divided into two types: concentric reducer and eccentric reducer.
The commonly used forming process is reduced diameter pressing, expanded diameter pressing or reduced diameter plus expanded diameter pressing. Stamping forming can also be used for reducing pipes of some specifications. The reducers forming process of reducing / expanding forming is to put the tube blank with the same diameter as the large end of the reducers into the forming die, and press along the axial direction of the tube blank to make the metal move along the die cavity and shrink. According to the size of reducing pipe, it can be divided into one-time pressing forming or multiple pressing forming. In addition to using steel pipe as raw material to produce large and small heads, stamping forming can also be used for some specificated reducers of steel plates. 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. Before connecting the reducers, wipe the socket side and the outside of the socket with a dry cloth for better welding.
