Fabrication Technology Of Tee Joint

The tee joint forming is a tube billet larger than the tee diameter, the size of the flattening is about the diameter of the tee, a hole is opened in the part of the tensile branch pipe, and the billet is heated and put into the forming die, and the die of the tensile branch pipe is loaded in the Tube billet. Under the action of the pressure, the billet is radially compressed, In the process of radial compression, the metal flows in the direction of the branch pipe and forms a branch tube under the tensile force of the die.

The whole process is formed by the radial compression of the tube billet and the stretching process of the branch, and unlike the hydraulic bulge tee, the metal of the Tee Joint branch is compensated by the radial movement of the tube billet, so it is also called the radial compensation process.

Due to the use of heating to suppress three-way, the material required to form a lower tonnage of equipment, hot-pressing tee on the material adaptability is wide, suitable for low-carbon steel, alloy steel, stainless steel materials, especially the large diameter and wall thickness of the tee, usually using this forming process.
