Hydraulic Bulging Process Of Stainless Steel Tee

The forming process of stainless tee is as follows:

a. Hydraulic bulging

Hydraulic bulging of 1 4 stainless steel tee pipe fittings is a forming process that expands the branch pipe through axial compensation of metal materials. The process is to use a special hydraulic press to inject liquid into a tube blank with the same diameter as 2 stainless steel tee, and squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The volume of the tube blank decreases after being squeezed, and the pressure of the liquid in the tube blank increases as the volume of the tube blank decreases. When the pressure required for the expansion of the 1 4 stainless tee branch pipe is reached, the metal material flows along the inner cavity of the mold under the dual action of the side cylinder and the liquid pressure in the tube blank to expand the branch pipe.
