Threaded Tee ASME B16.11 Fittings

Threaded tee used thread connection to combine with pipes.ASME B16.11 fittings are forged fittings belong to American Standard.Tees can divided as equal tee and reducing tee.These tees have same functions,the only difference is reducing tee can reduce the flow in piping system.

Rated 4.9/5 based on 385 customer reviews

The threaded tee is a “T” type pipe fitting. The branch pipe has two outlets and is perpendicular to the main pipe. It is used to change the direction of the pipe so that the pipe is 90 degrees perpendicular to the pipe.Threaded fittings are belong to forged fittings,ASME B16.11 fittings are represents all forged fittings in American Standard.


Threaded fittings are mainly used with small diameter pipes.Threaded fittings make the connection easy to operate,and also convenient for dismantle,based on this ,threaded fittings could save lots of cost for connecting pipes.Threaded fittings are including Elbow,Tee, Cross, Coupling, Cap, Swage Nipple, Bushing, Plug, Nipple, Union, Hex Nipple,Threadolet.


Threaded Types:




Equal:This is a Pipe fitting with the same size on three sides.

Reducing:The main pipe of these tee is different from the diameter of the branch pipe, and the diameter of the main pipe is larger than that of the branch pipe.



They have applications in many industries,including chemical processing, petroleum, refining, marine waste treatment, utilities / power generation, industrial equipment, natural gas compression and distribution industries. Tee pipe is also recommended for industrial equipment hydrodynamic system.
