Hot pressing of tee is to flatten the tube blank larger than tee diameter to the size of tee diameter
Cold drawn tee：A hole is opened at the position of the stretch branch pipe; the tube blank is heated and put into the forming die, and the die of the stretch branch pipe is installed in the tube blank; under the effect of pressure, the tube blank is compressed radially, and in the process of radial compression, the metal flows to the direction of the branch pipe and forms the branch pipe under the stretch of the die. The whole process is formed by the radial compression of the tube blank and the drawing of the branch pipe. Different from the hydraulic expansion tee, the metal of hot pressed tee branch is compensated by the radial movement of tube blank, so it is also called radial compensation process.
According to the production method, it can be divided into: top system, pressing, forging, casting, etc.
According to pipe diameter and size：The nozzle ends of equal tee are the same size，The size of main pipe connecting pipe of reducing tee is the same, while the size of branch pipe connecting pipe is smaller than the size of main pipe connecting pipe
