Carbon Steel Pipe Reducer 273.1*88.9*9.27 It is divided into two concentric and eccentric heads

Size head (different diameter pipe) is a pipe fitting used for pipe caliber. The forming process usually used is diameter compression, diameter compression or shrinkage and diameter compression, and stamping formation can also be used for some specifications.
Dimameter / expansion forming
The diameter forming process of the size head is to put the pipe billet equal to the diameter of the large end head into the forming mold, and move the metal along the axial direction of the tube billet and shrink the mold cavity. According to the size of the diameter diameter, it is divided into one pressing forming or multiple pressing forming.
Stping forming
In addition to using steel pipe, some steel plate can be produced by stamping forming process. The die shape used for the drawing is designed according to the inner surface size of the size head, and the steel plate after the die molding is formed.
Before bonding the size head, wipe the bearing side and the outside of the socket with a dry cloth, and wipe it clean with acetone when the surface has oil stains
