Two Forming Processes for Stainless Steel Tee Fittings

stainless steel t pipe pipe fittings are used where pipes have branches. Due to its convenience and simplicity, it is widely used in chemical, civil construction, machinery and equipment manufacturing, shipbuilding and other industries. stainless steel threaded reducing tee is a pipe fitting used as a branch of a pipe. At present, there are two common processes for making stainless steel threaded tee with seamless pipes: hydraulic bulging and hot pressing.
1. stainless steel unequal tee pipe fittings - hydraulic bulging.
stainless t fitting pipe fittings hydraulic bulging is a forming process that uses axial compensation of metal materials to bulge the branch pipe. In this process, a special hydraulic press is used to inject liquid into a tube blank with the same diameter as stainless tee fitting, and the two horizontal side cylinders of the hydraulic press are used to squeeze the tube blank, so that the volume of the tube blank is reduced after extrusion, 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 steel pipe tee branch pipe is achieved, the metal material flows along the inner wall of the mold under the dual action of the side cylinder and the liquid pressure in the tube blank, causing the branch pipe to expand.
