Below DN400 tees are definitely right for us!
The hydraulic bulging tee is a forming process of expanding the branch pipe through the axial compensation of the metal material.
The hydraulic bulging process of the cold drawn tee can be formed at one time, and the production efficiency is high; the thickness of the main pipe and the shoulder of the cold drawn tee are increased. Due to the large tonnage of the equipment required for the hydraulic bulging process of the cold-drawn tee, it is currently mainly used in the manufacture of standard wall thickness tees smaller than DN400 in China. The applicable forming materials are low-carbon steel, low-alloy steel, and stainless steel with a relatively low tendency to cold work hardening, including some non-ferrous metal materials, such as copper, aluminum, and titanium.
