Pipe tee is a pipe for pipeline branch. For using seamless tube manufacturing pipe tee is usually adopted by the process has two kinds of hydraulic bulging forming and hot pressing.
A hydraulic bulging: three links of hydraulic bulging 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 pressure, when pressure pipe tee branch pipe bulge out to 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.
2. Thermoforming: pipe tee thermoforming is greater than three links of the diameter of the tube billet, flattening diameter size, about to pipe tee at the site of the tensile branch open a hole; Tube billet heating, in the forming die, and within the tube billet load stretching pipe punching die; Under the action of pressure pipe by radial compression, the radial compression in the process of metal flow in the direction of branch pipe and branch pipe formed under tensile of progressive die. The whole process of the pipe is made by the radial compression and branch pipe drawing process and forming parts. Unlike hydraulic bulge forming pipe tee, hot-pressing pipe tee branch pipe of metal is of the pipe by the radial motion compensation, so also known as the radial compensation technology.
