Reducing Tee ASME B16.9
Pipe tees can be equal tee and reducing tee.These tees have same functions,the only difference is reducing tee can reduce the flow in piping system.ASME B16.9 is American Standard for butt welded fittings.
Reducing tee is a T-shaped pipe fitting with three branch pipes. It is used to divide pipes to adjust flow and change direction.ASME B16.9 is American Standard of butt welded fittings.
There are two types of fittings:Equal Tee and Reducing Tee.
Equal diameter tee, also known as straight tee, the branch diameter of the tee is the same as the pipe diameter of the tee.
The reducing tee has two outlets cut at 90 degrees with the main pipe, and the size of the branch pipe is smaller than the port of the pipeline.
Good general corrosion resistance and high strength
Good sulfide stress corrosion resistance
Resistance to chloride pitting and crevice corrosion
Higher resistance to chloride stress corrosion cracking
Easy to weld and conform
Equal Tee VS Reducing Tee
Steel Equal Tee pipe fittings: The three branches of tee have same diameters.
Steel Reducing Tee: The branch diameter is smaller than the main line diameter. Tee reducer is usually described as NPS diameters in 4”x 4”x 3”, 4”is the main line pipe diameter, and 3”is the reducing branch.
