  Carbon steel elbow to improve the use of performance

  ANSI B16.9 Sch40 Butt Weld Pipe Fitting Carbon Steel Elbow forming process is the use of special elbow push machine, core mold and heating device, in order to achieve in the mold on the blank in the push machine driven by the forward movement, in the movement of heating, expansion and bending Forming process. Carbon steel elbow deformation is characterized by the plastic deformation of metal materials before and after the volume of the law to determine the diameter of the tube diameter, the diameter of the tube is less than the diameter of the elbow, through the core mold to control the blank deformation process, so that the
