What should be paid attention to when making the pipe reducer?

　The expanding die is made of pipe reducer blanks with large diameter smaller than the diameter of the pipe reducer, and the inner die is expanded along the inner diameter of the pipe reducer blank. The process of expanding diameter is mainly to solve the condition that the diameter of the pipe with large diameter is not easy to be formed by shrinkage forming, and sometimes the method of expanding diameter and reducing diameter is combined in accordance with the forming needs of materials and products.

　　In the process of reducing or expanding deformation, cold or hot pressing is adopted according to different materials and variable diameters. Usually, the cold pressure is used as much as possible, but the condition of severe hardening, the thickening of the thickness of the wall or the material of the alloy steel should be hot pressed.

　　In addition to using steel pipe as raw material to produce different diameter ANSI B16.9 Carbon Steel Pipe Fitting Sch30 Concentric Pipe Reducer, some specifications of different diameter pipes can also be produced by stamping process with steel plate. The shape of the drawing die is designed according to the inside dimension of the different diameter pipe reducer, and the blanked steel plate is stamped and drawn with the stamping die.
