    What is Tee

    The ASME/ANSI B16.9 tee is T-shaped with two outlets,the two outlets are 90 degree direction change to the main line.ASME/ANSI B16.9 tee also looks like a short piece of pipe with a outlet(which is called branch).A pipe 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 is widely used as pipe fittings to connect pipelines with a pipe at a right angle,and is extensively used in pipeline networks to transport two-phase fluid mixtures.

    Common type of Tees

    Equal tee (or straight tee), means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.

    Reducing tee has a branch that is smaller than main run allows for branching off to a smaller pipe of equipment from main run.

    Lateral pipe tee means a pipe fitting which is similar to a tee but has a side opening outlet branch at a 45 degree angle.

    barred tee is a tee or any fitting with a branch used in pipelines that is pigged and has a restriction bar welded internally preventing the pig from traveling down a branch connection.

    TEES: Extrusion method (Hot Forming)

    The hot-extrusion process consists of enclosing a piece of metal, heated to forging temperature, in a chamber called a “container” having a die at one end with an opening of the shape of the desired finished section, and applying pressure to the metal through the opposite end of the container. The metal is forced through the opening, the shape of which it assumes in cross-section, as the metal flows plastically under the great pressures used.
