Grooved Mechanical Tee
Grooved Mechanical Tee Reducing
Threaded Reducing Tee


JIZHONG(G) Grooved Tee is also called pipe tee or tee pipe fittings, tee joint and so on. Mainly used to change the direction of the fluid, used at the branch pipe of the main pipeline. It can be classified according to the size of the pipe. Equal tee and Reducer tee.

Features and Benefits
The Difference between a JIZHONG(G) Grooved Tee and a Mechanical Tee
The mechanical tee is an opening on the straight pipe, and it can be stuck with a mechanical tee, the main pipe is the whole section, the branch pipe is a single pipe, needs one mechanical threaded tee, or one grooved mechanical tee plus one grooved coupling. In the ordinary grooved tee, three different direction pipes are connected by the grooved tee, the engineering quantity is one grooved tee and 3 grooved couplings.
Grooved Threaded Reducing Tee Detail
Grooved Threaded Reducing Tee are used to give branches from the main pipeline. The branch ends can be connected by thread, usually, the branch open diameter is smaller than the main pipeline. Because the smaller diameter pipes always adapt threaded ends. So these grooved threaded reducing tees are also normally used in the pipeline systems and are used for applications in a variety of industries such as chemical processing, refineries, petrochemicals and many other industries.
