Stainless Steel Tee
A tee is also called triplet,three way and “T” pieces and it can be used to either combine or split a fluid flow. Most common are tees with the same inlet and outlet sizes, but ‘reducing’ tees are available as well. it means the one or two ends are differ in dimension.due to this dimension differ,the makes the tee fittings with the capacity to control the volume when requried.
Steel pipe tee has three branches that can change fluid direction. It has T-shaped or Y-shaped, and include Equal Tee and Reducing Tee (Reducer Tee). Steel tee is widely used in pipe networks for convey liquids and gases.
A tee is the most common pipe fitting. It is available with all female thread sockets, all solvent weld sockets, or with opposed solvent weld sockets and a side outlet with female threads.When the size of the branch is same as header pipes, equal tee is used and when the branch size is less than that of header size, reduced tee will be used.
Types of Steel Pipe Tee:
According to branch diameters and functions there are:
Equal Tee
Reducing Tee (Reducer Tee).
According to connection types are:
Butt Weld Tee
Socket Weld Tee
Threaded Tee.
