  The forming of special pipe fitting tee is to flatten the tube blank larger than the tee diameter to about the tee diameter and make a hole in the part of the drawing branch pipe; the tube blank is heated and put into the forming die, and the special pipe fitting tee is inserted into the tube blank; the tube blank is radially compressed under the action of pressure, and the metal is directed to the special pipe fitting tee in the process of radial compression. To flow and form a special pipe fitting tee under the tensile of the die. The whole process is formed by the radial compression of the billet and the drawing process of special pipe fitting tee. Unlike hydraulic bulging tee, the metal of special pipe fitting tee is compensated by radial motion of tube blank, so it is also called radial compensation process.

  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.
