The hydraulic bulging process of stainless steel tees can be formed in one go, with high production efficiency; The thickness of the main pipe and shoulder wall of the stainless steel tee has increased.

Due to the large equipment tonnage required for the hydraulic bulging process of stainless steel tees, it is currently mainly used in the manufacturing of standard wall thickness stainless steel tees with a diameter less than DN400 in China. The suitable forming materials are low carbon steel, low alloy steel, and stainless steel with relatively low cold work hardening tendency,
