The equal tee is a chemical pipe fitting with three openings, namely one inlet and two outlets; or two inlets and one outlet, with equal-diameter nozzles.
The carbon steel equa tee has wide adaptability to materials, and is suitable for materials of low-carbon steel, alloy steel and stainless steel; especially the tee with large diameter and thick wall, usually adopts hot press forming process.
Our equal-diameter tees are made of high quality materials. We undergo rigorous quality inspections at all stages of production to ensure that quality and product dimensional tolerances are minimized. This product meets international quality standards, has good corrosion resistance, and is durable.

The hydraulic bulging of the equal tee is a forming process for expanding the branch pipe by axial compensation of the metal material. The process uses a special hydraulic machine to inject liquid into the tube blank equal to the diameter of the tee, and simultaneously presses the tube blank through the two horizontal side cylinders of the hydraulic machine. After the tube blank is squeezed, the volume becomes smaller, and the liquid in the tube blank becomes smaller as the tube blank becomes smaller and the pressure rises. When it reaches the pressure required for the stainless steel tee branch to swell, the metal material flows along the cavity of the mold under the double action of the liquid pressure in the side cylinder and the tube blank to swell out of the branch pipe.
