Special Pipe Fitting Tee manufacturer
Due to the use of heating to special pipe fitting tee, the equipment tonnage required for material forming is reduced. Special pipe fitting tee have wide adaptability to materials and are suitable for low carbon steel, alloy steel and stainless steel, Special Pipe Fitting Carbon Steel Tee with large diameter and thick pipe wall, which are usually formed by this process. The special pipe fitting tee hydraulic bulging is a forming process that expands the branch pipe by axial compensation of metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter of the tee and extrude the tube blank through two horizontal cylinders of the hydraulic press.
The volume of the tube blank decreases after extrusion. The liquid in the tube blank increases with the volume of the tube blank decreases. When the pressure required for special pipe fitting tee to bulge out is reached, The metal material flows along the die cavity under the dual action of the liquid pressure in the side cylinder and the tube blank, and the branch pipe bulges out.
