Hebei Shengtian Pipe Fittings Group specializes in the production of JIS B2312 Butter Weld Pipe Fitting Concentric Reducers. The pipe fitting reducer, also known as the big and small head, is one of the chemical pipe fittings and is used to connect two different pipe diameters. It is further divided into pipe fitting concentric reducer and pipe fitting reducer eccentric reducers.

The reducing forming process of the JIS B2312 Butter Weld Pipe Fitting Concentric Reducer is to put the tube blank with the same diameter as the large end of the reducer into the forming mold, and by pressing the tube blank in the axial direction, the metal moves along the mold cavity and shrinks into shape. According to the reducing diameter Depending on the size of the pipe diameter reduction, it can be divided into one-time pressing forming or multiple pressing forming.
The characteristic of the JIS B2312 Butter Weld Pipe Fitting Concentric Reducer is that its strength is significantly higher than that of carbon steel with the same carbon content, and it has good toughness and plasticity, as well as good weldability and corrosion resistance.
