Carbon steel concentric reducer is produced in strict accordance with the standard, also known as reducer. It is one of the chemical pipe fittings, which is used for the connection of two different pipe diameters. It is also divided into concentric reducer and eccentric reducer. The manufacturing process is as follows: the tube blank with the same diameter as the large end of the reducer is put into the forming die, and the metal moves along the die cavity and shrinks to form by pressing along the axial direction of the tube blank. According to the size of reducer, it can be divided into one-time pressing forming or multiple pressing forming. By pressing along the axial direction of the tube blank, the metal moves along the die cavity and shrinks. According to the size of reducer, it is divided into one-time pressing forming or several pressing forming.
