Stainless steel TEE is pipe fittings and pipe connectors. Tee has equal diameters and different diameters. The connecting ends of Equal TEE are all the same size; Reducing TEE has the same size of main pipe, but the size of branch pipe is smaller than that of main pipe.

Stainless steel TEE is a kind of pipe fittings used at pipeline branches. For the tee made of seamless pipes, the usual processes used are hydraulic bulging and hot press forming. The hydraulic bulging of 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 stainless steel TEE can be formed at one time, and the production efficiency is higher; the wall thickness of the main pipe and the shoulder of the stainless steel TEE are increased.

Due to the large tonnage of equipment required for the hydraulic bulging process of stainless steel TEE, it is mainly used in the manufacture of stainless steel tee with standard wall thickness less than DN400 in China. The applicable forming materials are low-carbon steel, low-alloy steel, and stainless steel with a relatively low tendency of cold work hardening, including some non-ferrous metal materials, such as copper, aluminum, and titanium. The difference between carbon steel and stainless steel TEE is generally believed to be the first aspect of corrosion resistance. However, in practical applications, stainless steel has excellent various properties that cannot be replaced by other steel types, such as some high-temperature resistant stainless steels, and the surface characteristics of stainless steel are widely used as decorative materials, as well as the excellent mechanical properties of stainless steel. Make it used in various manufacturing industries.
