ASME B 16.9 Tee Equal VS Reducing
ASME B16.9 tee is an American Standard butt welded fitting.BW tees can be two types:Equal Tees and Redcing Tees.These tees have similar functions but reducing tees can reduce the flow while equal tees can not.You could find the summary “Equal VS Reducing” in the content below.
ASME B 16.9 tee is a T-shaped pipe fitting with three branch pipes. It is used to divide pipes to adjust flow and change direction.Tees could be butt welded fittings or forged fittings.
The end of Butt welded fittings are connected to the pipe system by butt welding.Butt weld fittings provide permanent leak-proof performance.BW fittings could made from seamless or welded pipe,and then through several processes formed to get the shape of pipe fittings.The type of the ends could be PE(plain end),BE(bevelled end) and THD(threaded end).
The two types of tee are Equal and Reducing.
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.
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.
