Classification and application of stainless steel tee:
The stainless steel tee is a pipe fitting used at the branch of the pipeline. For the manufacture of tees using seamless tubes, the currently commonly used processes are hydraulic bulging and hot press forming.
Stainless steel tee
The hydraulic bulging of the stainless steel tee is a forming process that expands the branch pipe through the axial compensation of the metal material. The process is to use a special hydraulic machine to inject liquid into the tube blank equal to the diameter of the tee, and squeeze the tube blank through the centering movement of the two horizontal side cylinders of the hydraulic machine. After the tube blank is extruded, the volume becomes smaller and the tube blank The volume of the liquid increases and the pressure increases with the volume of the tube blank. When the pressure required to expand the stainless steel tee branch pipe is reached, the metal material flows along the cavity of the mold under the double action of the liquid pressure in the side cylinder and the tube blank to expand the branch pipe .
The hydraulic bulging process of the 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 the equipment required for the hydraulic bulging process of stainless steel tees, it is currently mainly used in the manufacture of stainless steel tees 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 manufacturing standards, it can be divided into national standard, electric 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
