Stainless steel TEE is used where the pipe has branches. Because of its convenience and simplicity, it is widely used in chemical industry, civil construction, machinery manufacturing, shipbuilding and other fields. Quality stainless steel TEE is a pipe fitting used for pipe branching. At present, there are two common processes for making quality stainless steel TEE for seamless pipes: hydraulic bulging and hot pressing.

1.The quality stainless steel TEE-hydraulic bulging.

The hydraulic bulging of quality stainless steel TEE pipe fittings is a forming process in which the branch pipe is bulged through the axial compensation of the metal material. In this process, a special hydraulic press is used to inject liquid into the billet with the same diameter as the tee, and the billet is squeezed by the two horizontal side cylinders of the hydraulic press, so that the volume of the billet after extrusion becomes smaller, and the pressure of the liquid in the billet is As the volume of the tube becomes smaller, it increases. When the pressure required for the expansion of the three-way branch pipe is reached, the metal material flows along the 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.

2.The quality stainless steel TEE-hot pressing.

The hot press forming of quality stainless steel TEE pipe fittings is to flatten the tube blank larger than the diameter of the tee to the size of the diameter of the tee, and open holes in the stretched part of the branch pipe. The tube blank is heated and placed in the forming mold. The tube blank is equipped with a mold for stretching the branch tube; under the action of pressure, the tube blank is radially compressed. In the process of radial compression, the metal flows to the branch tube. Branch pipes are formed under stretching. The whole process is formed by the radial compression of the tube blank and the stretching of the branch tube. Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.
