Reducing pipe is a type of pipe fitting, also known as a reducer, used for connecting two different pipe diameters. It is also divided into concentric reducer and eccentric reducer. When there is a change in the flow rate of the fluid in the pipeline, such as an increase or decrease, and the flow rate requirement does not change much, a reducer pipe needs to be used.
The commonly forming process for reducing pipes is shrinkage pressing, expansion pressing, or shrinkage plus expansion pressing. Punching can also be used for certain specifications of reducing pipes. Shrinkage forming is the process of placing a tube blank with the same diameter as the large end of the reducing tube into a forming die, and then applying pressure in the axial direction of the tube blank to compress it, causing the metal to move along the mold cavity and shrink into shape. Expanding forming involves using a tube blank with a diameter smaller than the large end of the reducing tube, and then using an internal punch to expand along the inner diameter of the tube blank.
