Stainless steel tees are fittings and pipeline connectors. Used at the branch of the main pipeline. Stainless steel tees can be divided into equal and reducing diameters, and the connecting ends of equal diameter tees are of the same size; The main pipe connection size of the reducing tee is the same, while the connection size of the branch pipe is smaller than the connection size of the main pipe.
Stainless steel tees are a type of pipe fittings used at pipe branches. For the manufacturing of tees using seamless pipes, there are usually two processes used: hydraulic bulging and hot pressing. Hydraulic bulging of stainless steel tees is a forming process that compensates for the axial expansion of branch pipes through metal materials. The process involves using a specialized hydraulic press to inject liquid into a tube blank with the same diameter as the three-way joint. The tube blank is then squeezed through two horizontal side cylinders of the hydraulic press, which move synchronously to the center. The volume of the tube blank decreases after being squeezed, and the pressure of the liquid inside the tube blank increases with the decrease in volume. When the pressure required for the expansion of the stainless steel three-way branch pipe is reached, the metal material flows along the inner cavity of the mold and expands out of the branch pipe under the dual action of the liquid pressure in the side cylinder and the tube blank.
The hydraulic bulging process of stainless steel tees can be formed in one go, resulting in high production efficiency; The main pipe and shoulder wall thickness of stainless steel tees have increased.
