Three-way hot press forming is to crush the tube blank larger than the diameter of the three-way tube to the size of the three-way diameter, and make a hole in the stretched branch pipe; the tube blank is heated and placed in the forming die and placed in the tube blank The die for drawing the branch pipe is inserted; under the action of pressure, the tube blank is compressed radially. During the radial compression, the metal flows toward the branch pipe and forms the branch pipe under the stretching of the die. The whole process is formed by the radial compression of the tube blank and the stretching process of the branch pipe. Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch pipe is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.
Because the tee is pressed after heating, the tonnage of the equipment required for material forming is reduced. Hot-pressed tees have a wide adaptability to materials, and are suitable for low-carbon steel, alloy steel, and stainless steel materials; especially tees with large diameters and thick pipe walls, this forming process is usually used.
Tee is a kind of chemical pipe fittings with three ports, namely one inlet and two outlets; or two inlets and one outlet, with T-shaped and Y-shaped, with equal-diameter orifices, and also with different-diameter pipes Where three identical or different pipelines meet. The main function of the tee is to change the direction of the fluid.
