A reducer (size head) is a type of pipe used for pipe diameter reduction. It is used for the joining of two different pipe diameters. It is divided into concentric heads and eccentric heads. The forming process usually adopted is a reduction press, a diameter expansion press, or a reduction diameter and a diameter expansion press. For some sizes of different diameter pipes, press forming can also be used.
The nozzles at both ends of the concentric reducer are centered on the same axis. When the diameter is reduced, the position of the tube is calculated by the axis, and the position of the tube is constant. Generally, it is used for gas or vertical liquid pipe diameter reduction.

The reduction forming process of the concentric reducer is to put a tube blank having the same diameter as the large end of the large and small heads into a forming mold, and to move the metal along the cavity and shrink and form by pressing in the axial direction of the tube blank. According to the size of the reducer of the reducer, it is divided into one press forming or multiple press forming.
Because the concentric reducer has good corrosion resistance, it enables the structural components to maintain the integrity of the engineering design. The chromium-containing concentric reducer also combines mechanical strength and high elongation, making it easy to manufacture parts to meet the needs of architects and structural designers.
