Mechanical tees provide the same purpose as regular tees. They are frequently employed in the installation of fire protection pipes and sprinkler pipes because they may be used to split the flow of water into two directions and directly connect branch pipes on steel pipes.

Grooved flanges have grooves on the connecting end face. They are disc-shaped elements that are commonly used in pipeline engineering. They have mechanical constructions with flanges that can be joined by edge bolts.

A grooved pipe reducer is a pipe fitting that joins two pieces of pipe. It is classified as concentric or eccentric. They may be required to be employed when the flow in a piping system must be reduced or enlarged, such as when the hydraulic nature of the piping system requires it.

A grooved tee is used at the branch pipe of the main pipe in a pipe system to separate the flow of water into two directions. There are two types of grooved tees: equal diameter and diminishing diameter. It is utilized at the intersection of three pipes that are either the same or distinct, and it is further classified as a G type tee and a S type tee.
