DN50 ASME B16.5 WP321 Stainless Steel Tee Fittings

ASME B16.5 WP321/347 Stainless Steel Equal Diameter Tee

Stainless steel tee is a kind of pipe fittings used at pipeline branches. For the manufacture of tee joints with seamless pipes, the usual processes are hydraulic bulging and hot pressing. 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. The two horizontal side cylinders of the hydraulic press synchronize the centering movement to extrude the tube blank. The volume of the tube blank becomes smaller after being squeezed, and the inside of the tube blank 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 cavity of the mold under the dual action of the side cylinder and the liquid pressure in the tube to expand the branch tube.

Classification

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 relatively low cold work hardening tendency, including some non-ferrous metal materials, such as copper, aluminum, and titanium.

According to the manufacturing standard

It can be divided into national standard, electrical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc., as follows: GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/ T21635, DL/T 695, SY/T 0510, DIN 2615.
