WP9 DN500*DN400 pipe tee fittings High pressure Equal Tee Fitting, T Connector Plumbing

Tee, also known as pipe fitting tee or tee pipe fitting, tee joint, is used at the branch pipe of the main pipe. The tee can be divided into equal diameter and reducing diameter, and the nozzle ends of equal diameter tee are of the same size; The main pipe connecting pipe size of reducing tee is the same, while the connecting pipe size of branch pipe is smaller than that of main pipe.

There are two kinds of process methods: hydraulic bulging and hot pressing. The hydraulic bulging of tee is a forming process of expanding branch pipe through axial compensation of metal material. The hydraulic bulging process of TEE can be formed at one time and has high production efficiency; The wall thickness of the main pipe and shoulder of the tee increased. Tee hot pressing is to flatten the pipe blank larger than the tee diameter to the size of the tee diameter, and open a hole at the part of the stretched branch pipe; The tube blank is heated and put into the forming die, and the die for drawing the branch pipe is installed in the tube blank; Under the action of pressure, the tube blank is compressed radially. In the process of radial compression, the metal flows to the branch pipe and forms a branch pipe under the tension of the die
