Do you know grooved pipe fittings?
Grooved pipe fitting is a newly developed type of steel pipe connection pipe fitting, also called clamp connection, which has many advantages.
The design specification of automatic sprinkler system proposes that the connection of system pipelines should use grooved connectors or screw thread and flange connections; pipes with a diameter equal to or greater than 100mm in the system should use flanged or grooved connectors in sections.

Introduction to grooved pipe fittings:
Grooved fittings can be divided into two broad categories:
①The pipe fittings that play the role of connection and sealing include grooved rigid couplings, grooved flexible couplings, mechanical tee and groove flanges;
②The pipe fittings that play the role of connection and transition include elbows, tees, crosses, reducers, end caps, etc.
The groove connection fittings that serve as both connections and sealing primarily consist of three parts: a sealing rubber ring, a clamp, and a locking bolt. The rubber sealing ring located on the inner layer is placed on the outside of the connected pipe and fits with the pre-rolled groove, and then a clamp is fastened on the outside of the rubber ring, and then fastened with two bolts. Groove connections have very reliable sealing performance due to the unique sealable structure design of the rubber sealing ring and clamp. With the increase of fluid pressure in the pipe, its sealing performance is correspondingly enhanced.
Features of grooved pipe fittings:
- The installation speed is fast.The grooved pipe fittings only need to be installed with the standard parts supplied and do not need subsequent work such as welding and galvanizing.
- Easy to install.The number of bolts to be fastened for grooved pipe fittings is small, the operation is convenient, and only a wrench is required for disassembly and assembly.
- Environmental protection. The piping and installation of grooved pipe fittings do not require welding or open flame operation. Therefore, there is no pollution, no damage to the galvanized layer inside and outside the pipe, and it will not pollute the construction site and the surrounding environment.
- It is not limited by the installation site and is easy to maintain. The grooved pipe fittings can be pre-assembled first and can be adjusted arbitrarily before the bolts are locked. The piping sequence has no direction.
