Basic principle of stainless steel tee

Stainless steel tee is a kind of pipe fitting used at the branch of pipeline. For the manufacture of tee with seamless pipe, the commonly used processes include hydraulic bulging and hot pressing.
The hydraulic bulging of stainless steel tee is a forming process of expanding the branch pipe through the axial compensation of metal materials.
The process is to use a special hydraulic press to inject liquid into the pipe blank with the same diameter as the tee, and squeeze the pipe blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The volume of the pipe blank becomes smaller after extrusion, and the liquid in the pipe blank increases with the volume of the pipe blank. When the pressure required for the expansion of the stainless steel tee branch pipe is reached, The metal material flows along the inner cavity of the die and expands out of the branch pipe under the dual action of the liquid pressure in the side cylinder and the tube blank.
The hydraulic bulging process of stainless steel tee can be formed at one time with high production efficiency; The wall thickness of main pipe and shoulder of stainless steel tee is increased.
