Stainless steel tee‘s hydraulic bulging process is through the metal materials of axial compensation bulge out a kind of branch pipe forming process.
The process is to use special hydraulic press, with three links within the tube billet diameter equal injection liquid, through the two horizontal side of the hydraulic cylinder synchronization of the motion of tube billet, billet after squeezed smaller volume, smaller volume of liquid with the tube billet inside the tube billet and the pressure increases, when the stainless steel tee’s branch pipe bulge out to the pressure, the metal material in the liquid in the cylinder and the pipe pressure under the dual role of flow along the mold cavity and the branch pipe.
Stainless steel tee hydraulic bulging process can be a forming, high production efficiency; Stainless steel tee head and shoulders of wall thickness are increased.
Stainless steel tee:
By the hydraulic bulging process equipment for stainless steel tee tonnage is larger, the current domestic is mainly used for less than the standard of DN400 wall thickness in the manufacturing of stainless steel tee. Its applicable forming material for cold hardening tend to be relatively low low carbon steel, low alloy steel, stainless steel, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc.
