Aluminum Tee Pipe Fittings Tee is an aluminum alloy pipe fitting used to divide the main flow into two flows or merge two flows. Because the shape of the tee pipe is like the English letter "T", it is called Tee.
Common types of aluminum pipe tee fittings
The main pipe in a tee is usually called the main pipe or straight pipe, and the other branch pipe is called the branch pipe. The diameter of the branch pipe can usually be less than or equal to the straight pipe. If the branch pipe is the same as the straight pipe, the tee is an equal diameter tee, otherwise it is an unequal diameter tee or a reducing tee.
Equal tee aluminum pipe fitting- Equal tee has three outlets with the same diameter, suitable for connecting pipes of the same size, such as 6061 round tube or 6063 round tube, commonly used in structural systems. It is usually used in systems where flow distribution needs to be equal in all directions.
Reducing tee aluminum pipe fitting- Reducing Tees feature one outlet diameter that is different from the other two, allowing pipes of different sizes to be connected. This type is suitable for systems where flow needs to be redirected from a larger pipe to a smaller pipe or vice versa. For more options, check our aluminum reducer tube fittings.
Lateral tee aluminum pipe fitting- The outlet of a lateral tee branches at a 45 degree angle instead of a 90 degree angle. This fitting is used in systems that require a smoother flow transition to reduce turbulence and pressure drop.
Threaded aluminum pipe tee- A tee with threaded ports, also a common fitting, may not be as reliable as welded connections in high-pressure systems. Pair with our threaded aluminum pipes for complete system solutions. Therefore, it is often used in low to medium pressure piping systems and can withstand pressure ranges from 150 psi to 3000 psi.
Socket weld aluminum pipe tee fitting- To connect three aluminum pipes using a socket weld method. Each port has a socket, into which one end of the pipe is inserted and then welded in place. Socket welding provides a high-strength and high-seal connection, suitable for high-pressure and high-temperature piping systems.
Butt weld aluminum pipe tee fitting- Butt weld tees are aluminum elbows formed by hot pressing or forging. Their connection method involves directly butt welding the tee to the aluminum pipe. They are typically made from 6061 aluminum pipe and are commonly used in high-pressure environments.
Flanged aluminum pipe tee fitting- A flanged tee is a welded pipe tee with three flanges, used in larger diameter pipes. It allows for easy installation and removal using bolts and flanges, ideal for industries needing frequent maintenance, such as water supply and sewage systems. Often paired with aluminum seamless tubes or thick wall aluminum pipes for added strength.
