Stainless steel tee is a kind of pipe fittings used at pipeline branches

Stainless steel tees are pipe fittings and pipe connectors. Used in the branch pipe of the main pipeline. Stainless steel tees are divided into equal diameters and reducing diameters. The connecting ends of equal diameter tees are all the same size; the main pipe connecting size of reducing tees is the same, while the connecting pipe size of branch pipes is smaller than that of the main pipe. Stainless steel tee is a type of pipe fitting used at the branch of the pipeline. For the manufacture of tee joints with seamless pipes, the currently commonly used processes include hydraulic bulging and hot press forming. The hydraulic bulging of the stainless steel tee is a forming process in which the branch pipe is expanded by the axial compensation of the metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and to squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The pressure of the liquid increases as the volume of the tube becomes smaller. When the pressure required for the expansion of the stainless steel three-way branch tube 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 to expand the branch tube. . The hydraulic bulging process of the stainless steel tee can be formed at one time, and the production efficiency is high; the wall thickness of the main pipe and the shoulder of the stainless steel tee are increased.
