The production of 3 way copper elbow fitting. The forming of 3 way copper elbow fitting is to flatten a tube blank larger than the diameter of the tee to the size of the diameter of the tee, and open a hole in the stretched branch tube; the tube blank is heated and placed Into the forming die, and insert a punching die for stretching the branch pipe into the tube blank; the tube blank is radially compressed under the action of pressure, and the metal flows in the direction of the branch tube during the radial compression process and forms the branch tube under the stretching of the die .

The whole process is formed by the radial compression of the tube blank and the stretching process of the branch tube. Different from the hydraulic bulging tee, the metal of the branch pipe of the tee joint is compensated by the radial movement of the tube blank, so it is also called the radial compensation process
