The tee is among the most common of industrial pipe fittings. Depending on the application, tees are available as all-female threaded sockets, all solvent welded sockets or a combination. They are available in a variety of impact and corrosion resistant alloys, including duplex and super duplex.

Tees are 3-ended pipe fittings designed to offer a second outlet from a main, through-running pipe.

Tees are used to connect pipes of the same or differing diameters. A blocked-off tee is useful for changing the direction a pipe runs, where an elbow would not be an option (for example, to offer an observation “hatch”). The most common tees are straight tee pipe fittings, a straight-through tee with a 90-degree branch-off of the same diameter.

Tee fittings are supplied as equal or reducing tees. The above is an example of an equal tee, as all three outlets are the same size. Reducing tees have a combination of different sized outlets, and are used for branch connections from larger lines.

Standard tees are typically belled on all three ends. However, any combination of belled or plain ended tees can be produced, although they may not all be available in duplex steel unless they are custom made. Similarly, tees are available in a large range of size combinations. Unusual combinations can be accommodated by using component parts of different tees, reducing tees or reducer fittings.

We at ChemiPetro supply a wide range of tee fittings to the industry and will happily provide a quote on custom made tees, including duplex and super duplex fittings.
