Grooved Pipe Fittings

Grooved Coupling Rigid Coupling XGQT01

We offer tongue and groove rigid couplings that are suitable for applications requiring rigidity. The built-in teeth firmly grasp the pipe ends to prevent unwanted flexing. The specific items list will be posted on FM and UL's websites.

Grooved Coupling, usually has two different types: Rigid Coupling and Flexible Coupling.

Grooved Rigid Couplings are used in general piping joint applications where rigidity is required. The rigid couplings provide a completely rigid connection similar to traditional flanged, welded, and threaded piping connections with the help of grip teeth. It eliminates or reduces angular deflection, axial displacement, and rotation after installation. This makes it easy to install even very long pipelines without angular deflection. The clamp connection is a new type of steel pipe connection solution, also called a groove connector, grooved rigid couplings, which has many advantages. The design specification of automatic sprinkler system proposes that the connection of system pipes should adopt grooved connectors or threaded and flanged connections; pipes with a diameter equal to or greater than 100mm in the system should be segmented with flanges or grooved connectors connection. The groove connecting pipe fittings that play the role of connecting and sealing is mainly composed of three parts: the sealing rubber ring, the clamp, and the locking bolt. The rubber seal ring located in the inner layer is placed on the outside of the connected pipe and fits with the pre-rolled groove, and then buckle the clamp on the outside of the rubber ring, and then fasten it with two bolts. Because its rubber sealing ring and clamp adopt a unique sealable structural design, the grooved connector has good sealing performance, and as the fluid pressure in the pipe increases, its sealing performance is correspondingly enhanced.
