The difference between mechanical tees and groove tees

A mechanical tee is opened on a straight pipe and can be clamped with a mechanical tee. The main pipe is a whole section, and the branch pipe is a single piece. The engineering quantity is one tee (mechanical threaded tee), or one tee+one steel clamp (mechanical clamp tee); A regular trench tee is a method of connecting three pipe sections using a trench tee; The engineering quantity includes one tee and three steel clamps. In fire engineering, mechanical tees are used as the main pipeline and mechanical openings are directly used to connect branch pipes through dedicated fasteners; Reducing tee, such as DN150 * 100: the main pipe is DN150, the branch pipe is DN100, and there are rarely three finished products with different diameters for each opening; The groove tee refers to only one type of pipe fitting connection method, which is mostly divided into: welding, flange, clamp (groove type)

Mechanical tees have the same function as ordinary tees. It can be used to directly connect branch pipes to steel pipes, and has many applications in the installation of fire protection pipelines and sprinkler pipelines. Mechanical tees can be used when diversion or merging is required.

Installation method: First, use a drilling machine to drill holes on the steel pipe, then clip the mechanical tee into the hole, and seal the hole with a sealing ring along the pipe wall. There are two types of mechanical three-way splicing and groove type. When connecting the mechanical tee, the gap between the mechanical tee and the hole should be checked, and all parts should be evenly distributed before tightening in place; The spacing between mechanical tee openings should not be less than 1m.
