Specializing in the production of stainless steel tee

The stainless steel tee is a pipe fitting for a pipe branch. For the use of seamless pipe manufacturing tee, usually used by the process of hydraulic bulging and hot forming two kinds. The hydraulic bulging of stainless steel tee is a forming process of compensating the bulging of branch pipe through the axial direction of metal material. The process is to use special hydraulic press, with three links within the tube billet diameter equal injection liquid, through the two horizontal side of the hydraulic cylinder synchronization of the motion of tube billet, billet after squeezed smaller volume, smaller volume of liquid with the tube billet inside the tube billet and the pressure increases, when the stainless steel tee branch pipe bulge out to the pressure, the metal material in the liquid in the cylinder and the pipe pressure under the dual role of flow along the mold cavity and the branch pipe.

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

Due to the large tonnage of equipment required by the hydraulic bulging process of stainless steel tee, it is mainly used in the manufacturing of stainless steel tee with standard wall thickness less than DN400 in China. The suitable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low cold hardening tendency, including some non-ferrous metal materials, such as copper, aluminum and titanium.

According to the manufacturing standards, it can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc. The details are as follows :GB/T12459,GB/T13401,ASME B16.9,SH3408, SH3409,HG/T21635,DL/T 695,SY/T 0510,DIN 2615.
