Seamless Welding Technology Of Stainless Steel Tee

Stainless Steel Weld Tee is a kind of connecting pipe fitting used for pipeline branching. At present, there are two main processes for seamless welding of stainless steel tees: hydraulic bulging and hot pressing. Compared with traditional welded tees, seamless welded tees have higher sealing and safety. The following is a brief introduction to this knowledge.

The hydraulic bulging process of stainless steel tees is to inject liquid into the tube blank of the same diameter as the stainless steel tee through a hydraulic press. Through the impact force and pressure, the volume of the tube blank becomes smaller and the pressure increases until the pressure required for the expansion of the stainless steel tee branch is reached. The metal material is pressed out of the branch.

The hot pressing process of stainless steel tees is to form a tube blank larger than the diameter of the tee through radial compression of the tube blank and stretching of the branch part.
