Tee

Pipe tee is used for distributing or collecting the fluid from the run pipe. It is a short piece of pipe with a 90-degree branch at center. There are two types of Tee used in piping, Equal / Straight Tee and Reducing / Unequal Tee.

Equal Tee

In straight tee, the diameter of the branch is same as the diameter of the Run (Header) Pipe.

Reducing Tee

In reducing tee, diameter of the branch size is smaller than the diameter of the Run (Header) Pipe

Barred Tee

A barred tee which is also known as a scrapper tee is used in pipelines that are pigged. The branch of the tee has a restriction bar welded internally to prevent the pig or scrapper to enter the branch. The bars are welded in the branch in a way that it will allow restriction free passage of the pig from the run pipe.

Wye Tee / Lateral

It is a type of Tee which has the branch at a 45° angle, or an angle other than 90°. Wye tee allows one pipe to be joined to another at a 45° angle. This type of tee reduces friction and turbulence that could hamper the flow. Wye tee is also known as a lateral.
