Stainless steel tee

The stainless steel tee is an important connector for pipe fittings and pipes, which is used at the branch pipe of the main pipe to reduce the connection port. Stainless steel tees can be divided into equal diameter tees and reducing tees. The size of the main pipe and the end of the connecting pipe of the equal diameter tee is the same, while the size of the main pipe connecting pipe of the reducing tee is the same, and the size of the branch pipe connecting pipe is smaller than the size of the main pipe connecting pipe

The stainless steel tee has a bright appearance and smooth inner wall, allowing the tap water to flow smoothly in the pipeline at an appropriate speed without erosion, thus avoiding secondary pollution to the water source. Stainless steel tees have excellent characteristics such as good strength, good ductility and health. With these advantages, stainless steel tees are widely used in indoor and outdoor building water supply, compressed gas pipelines in plant equipment and petrochemical industries

Stainless steel tee is a kind of pipe fitting used for branch pipe. In terms of manufacturing tee with seamless pipe, the commonly used processes are hydraulic bulging and hot pressing. The hydraulic bulging of stainless steel tee is a forming process of expanding branch pipe by axial compensation of metal materials. The process is to use a one-to-one hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and extrude the tube blank through the synchronous centering movement of two horizontal side cylinders of the hydraulic press. The volume of the tube blank becomes smaller after being extruded, and the pressure of the liquid in the tube blank increases with the reduction of the tube blank volume. When the pressure required for the expansion of the stainless steel tee branch pipe is reached, Under the double action of the side cylinder and the liquid pressure in the tube blank, the metal material flows along the inner cavity of the die and bulges out the branch pipe

The hydraulic bulging process of stainless steel tee can be formed at one time with high production efficiency; The wall thickness of the main pipe and shoulder of the stainless steel tee has been increased

Stainless steel tees can be divided into T-type and Y-type according to their appearance. T-type tees are right angled bends for flow diversion, while Y-type tees divide two pipelines into one. Therefore, the fluid resistance of Y-type tees is relatively small compared with that of T-type tees. Y-type tees can be used in industries with strict flow rate requirements to protect the smoothness of water bodies

Because the hydraulic bulging process of stainless steel tees requires large tonnage of equipment, it is mainly used for the manufacture of stainless steel tees with standard wall thickness less than DN400 in China. The applicable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low cold work hardening tendency, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc
