Manufacturers Supply Silver Pipe End Reducer Alloy Steel Pipe Fittings Reducer

The size head (reducing pipe) is a pipe fitting for the diameter of the pipe. The commonly used forming process is reducing pressing, expanding pressing or reducing plus expanding pressing, and stamping can also be used for some specifications of reducing tubes.

Reducing/expanding forming

The process of reducing the size of the head is to put the tube blank with the same diameter as the big end of the head into the forming die. By pressing the tube blank along the axial direction, the metal moves along the die cavity and shrinks into shape. According to the size of the reducing tube, it is divided into one pressing forming or multiple pressing forming.

Stamping

In addition to the use of steel pipes as raw materials to produce small heads, some specifications of small heads can also be produced by steel stamping process. The shape of the die used for drawing is designed according to the size of the inner surface of the size head, and the steel plate after blanking is pressed and drawn by the die.
