Stainless Steel Tee

ASTM A403 Equal/ Reducing Tees manufacturer in India

Stainless Steel Tee

As a leading Stainless Steel Tee manufacturer in India, we produce tees in all grades of stainless steel. There are different types of pipe fittings in use and tee is one the most common fittings. The ANSI B16.9 SS Threaded Tee belongs to a standard governing fittings and pipes of nominal size ½ inches to 48 inches. The threaded tee has threads instead of sockets.


So it is easy to fit with threaded pipes. There are different grades of stainless steel. We produce Stainless Steel Buttweld Unequal Tee which has differently sized ends. This allows differently sized pipes to be connected in one joint. A tee allows 3 pipe endings to be connected together in one joint. The equal tee is used to connect pipes of the same size. We manufacture fittings in grade steel as well. The SS Buttweld Equal Tee manufactured by us is easy to weld with. It has the buttweld which provides extra grip to the welding. The ASME B16.9 Lateral Tee Dimensions differ with schedules and nominal sizes. The nominal sizes change according to standards. Also, the reducing tee can reduce the size of pipeline at the joint. The ASTM A403 Stainless Steel Flanged Reducing Tee is made up of a forged and rolled austenitic SS material. It can be used interchangeably with the SS Reducing Tee or the Stainless Steel Threaded Reducing Tee. Customers can contact Great Steel & Metals for further details.

Heat Resistance SS Split Tee

Stainless steel Tee offer great oxidation resistance. In any case, the structural stability of this grade falls at high temperatures, especially above 400°C.

ASTM A403 Reducing Tees Heat Treatment

SS Tee can be solution heat treated at 1090 to 1175°C, following by rapid cooling. Thermal treatment is suitable for solidifying these grades.

Application of SS Reducing Tee

  • Seawater cooling devices
  • Oil refinery components
  • Gas scrubbing plants
  • Pulp and paper processing industries
  • offshore process equipment
  • chemical industry
