The heating forming tee machine is to compress the tube blank larger than the tee diameter to the size of the three-way diameter and open a hole at the stretch branch pipe. The billet is heated and put into the forming die. The whole process is formed through the radial compression of the billet and the stretching process of the branch pipe. Different from the hydraulic bulging tee, the metal of the hot pressing tee branch pipe is compensated by the radial motion of the pipe billet.

The tonnage of equipment required for material forming is reduced due to the use of a heated pressing tee. Hot pressing tee has wide adaptability to materials, suitable for low carbon steel, alloy steel, stainless steel materials; In particular, large diameter and tube wall thickness of the tee, usually using this forming process.of tee machine。
