High pressure tee is a kind of pipe fittings. Hot-pressed tee is a kind of tee made by hot-pressing process. The hot-pressing tee is made by heating the tube with equipment, and then cutting and heating it to above the critical temperature. After holding it for a period of time, it is quickly put into the quenching agent, so that the temperature is suddenly reduced, and it is made by a method of cooling more than the critical cooling rate Into the three links. Treatment method Quenching is to heat the tee above the critical temperature, keep it for a period of time, and then quickly put it in the quenching agent to make the temperature suddenly drop, and cool at a rate greater than the critical cooling rate to obtain martensite-based Heat treatment method for unbalanced organization.

High-pressure tee forming is to flatten the tube blank larger than the diameter of the tee to the size of the tee diameter, and open a hole in the stretched branch tube; the tube blank is heated, placed in the forming die, and installed in the tube blank Into the die for stretching the branch pipe; the tube blank is radially compressed under the action of pressure, and the metal flows in the direction of the branch pipe during the radial compression process 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 tube. Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process. As the tee is pressed after heating, the equipment tonnage required for material forming is reduced.
