Tee

Pipe tee, also known as tee pipe, is a kind of pipe connection, mainly used in pipe branches. It usually has three openings, including one inlet and two outlets, or two inlet and one outlet, thus changing the direction of the fluid. Tee pipe fittings are widely used in various industrial fields, such as medicine, water, energy and construction, especially in places where fluid direction needs to be changed.

Tee fittings can be classified according to different criteria:

According to the classification of pipe diameter, there are same diameter tee and reducing tee. The same diameter tee is a tee with the same diameter of the main pipe and the branch pipe, while the reduced diameter tee is a tee with the branch pipe diameter less than the main pipe diameter.
According to the classification of butt forms, there are four kinds of butt welding type, socket type, sleeve type and thread type. The butt welded tee is a tee welded after docking with the connecting pipe; The socket three-way is to insert the connecting pipe into each end of the tee before welding or welding; Each end of the bushing tee is a bushing joint, and the pipe fitting is inserted and fastened; Threaded three-way is to connect pipe fittings in a threaded manner.
According to the material classification, tee pipe fittings can be divided into stainless steel tee, carbon steel tee, copper tee, PVC tee, ductile iron tee and so on.
According to the branch pipe form classification, there are positive tee and oblique tee. The positive tee is a tee fitting with a vertical branch pipe, while the oblique tee is a tee fitting with a certain Angle between the branch pipe and the main pipe.
In the selection and use of tee pipe fittings, it is necessary to select the appropriate type, specification and material according to the specific engineering requirements and the characteristics of the pipeline system to ensure the normal operation and service life of the pipeline system. At the same time, it is also necessary to follow the relevant installation and maintenance specifications to ensure the safety and reliability of pipe fittings.
