Hydraulic Bulging Steel Pipe Fittings


1/8' Welding Steel Pipe Fittings


Tee can be divided into stainless steel tee, carbon steel tee, copper tee, PVC tee, etc. For using seamless tube to manufacture tee joint, there are two kinds of commonly used processes: hydraulic bulging and hot pressing. Because of its convenience and simplicity, it is widely used in chemical industry, civil construction, machinery manufacturing, shipbuilding industry and other fields.

The hydraulic bulging technology of stainless steel tee is a forming process of expanding branch pipe through axial compensation of metal material.

Hydraulic bulging is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and extrude the tube blank through two horizontal side cylinders of the hydraulic press.

The volume of the tube becomes smaller after being extruded, and the pressure of the liquid in the tube increases with the decrease of the volume of the tube blank. The metal material will flow along the die cavity under the double action of the side cylinder and the liquid pressure in the tube blank to expand out of the branch pipe.

The results show that the hydroforming process of stainless steel tee can be formed at one time, and the production efficiency is high; the wall thickness of main pipe and shoulder of no tee is increased.

Due to the large tonnage of equipment required for the hydraulic bulging process of stainless steel tee, at present, it is mainly used for manufacturing stainless steel tee with standard wall thickness less than dn400 in China.
