  Stainless steel tees are fittings and pipe fittings. The main pipe should be used at the branch pipe. Stainless steel tees can be divided into equal diameter and different diameter, and the nozzle ends of equal diameter stainless steel tees are of the same size; the nozzle sizes of different diameter stainless steel tees are the same, while the nozzle sizes of branch pipes are smaller than the nozzle sizes of main pipes.

  The stainless steel tee is a kind of pipe fitting used for the branch of pipeline. For the use of seamless tube manufacturing stainless steel tee, the current commonly used processes are hydraulic bulging and hot-pressing forming two. Hydraulic bulging of stainless steel tee is a forming process of compensated bulging branch pipe with metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter of the stainless steel tee, and extrude the tube blank through two horizontal cylinders of the hydraulic press.

  The volume of the tube blank decreases after extrusion, and the liquid in the tube blank increases with the volume of the tube blank decreases. When the pressure required for the expansion of the stainless steel tee branch pipe is reached. When the force is applied, the metal material flows along the die cavity under the dual action of the liquid pressure in the side cylinder and the tube blank, and the branch pipe bulges out.

  The hydraulic bulging process of stainless steel tee can be formed at one time with high production efficiency, and the thickness of main pipe and shoulder of stainless steel tee can be increased.
