Manufacturing process and application of seamless reducer in Hebei Juyuan

Manufacturing of seamless reducer: reducer (reducer) is a kind of pipe fitting used at the pipe reducer. The commonly used forming process is reducing pressing, expanding pressing or reducing plus expanding pressing. For some specifications of reducer, stamping can also be used
Reducing/expanding forming:
The reducing forming process of seamless reducer is to put the tube blank with the same diameter as the big end of the reducer into the forming die, and make the metal move along the die cavity and shrink to form by pressing along the axial direction of the tube blank. According to the size of reducer, it can be divided into one press forming or multiple press forming
In the process of reducing or expanding deformation and pressing, cold pressing or hot pressing shall be adopted according to different materials and reducing conditions. Generally, cold pressing shall be adopted as far as possible, but hot pressing shall be adopted for severe work hardening caused by multiple reducing, thick wall or alloy steel materials

Seamless reducer standard: national standard, American standard, British standard and various non-standard high pressure stamping
