Y-shaped tee, also known as pipe fitting tee or tee fitting, tee joint, etc. Mainly used to change the direction of the fluid, used at the branch of the main pipeline. It can be classified by pipe diameter size. Generally made of materials such as carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon carbide, PVC, etc

A three-way valve has three openings, one for purchasing and two for exporting; Or two types of chemical pipe fittings, one for import and one for export, with T-shaped and Y-shaped fittings, equal diameter fittings, and different diameter fittings, used at the confluence of three identical or different pipelines. The main function of a tee is to change the direction of the fluid

Hydraulic bulging of tees is a forming process that uses axial compensation of metal materials to expand branch pipes. The process involves using a one-on-one hydraulic press to inject liquid into a pipe blank with the same diameter as the three-way pipe. The pipe blank is squeezed through synchronous centering motion of the two horizontal side cylinders of the hydraulic press. The volume of the pipe blank decreases after being squeezed, and the pressure inside the pipe blank increases as the volume of the pipe blank decreases. When the pressure required for the expansion of the three-way branch pipe is reached, Under the dual action of liquid pressure in the side cylinder and tube blank, the metal material flows along the inner cavity of the mold and expands out of the branch pipe
