what is grooved pipe fittigns?
Grooved pipe fitting is a new type of steel pipe connection fittings, also called grooved coupling, which has many advantages. As an advanced pipeline connection method, grooved pipe fittings can be either exposed or buried, including rigid coupling and flexible coupling. Therefore, it has a broad scope of application.
According to the system: it can be used for fire water system, air conditioning cold and hot water system, water supply system, petrochemical pipeline system, thermal power and military pipeline system, sewage treatment pipeline system, etc.;
According to the pipe material: it can be used to connect steel pipes, copper pipes, stainless steel pipes, plastic-lined steel pipes, ductile iron pipes, thick-walled plastic pipes, hoses and valves with steel pipe joints and flange joints.

rigid vs flexible grooved coupling
Grooved couplings, also known as (flexible grooved coupling or rigid grooved coupling) are all grooved fittings. However, their application is different. Rigid couplings are generally used in fire fighting pipeline systems, while flexible couplings are suitable for use in water treatment equipment pipeline connection systems.
The rigid grooved coupling adopts the concave-convex groove design, and the pipeline system connected with the rigid coupling is in a rigid state, so that the pipe cannot produce axial and radial displacement.
The flexible coupling adopts a flat design: after connecting the pipe with the flexible coupling, the pipe is allowed to have axial displacement and rotation angle, so that the piping system is in a flexible state.
The main material of rigid couplings on the market is ductile iron, and the materials of flexible coulings on the market are stainless steel and ductile iron. Rated working pressure of rigid couplings is 600psi, flexible couplings rated working pressure is between 350psi and 1200psi.
