Grooved Fitting System

Grooved Piping System in Stainless Steel

A grooved pipe joint is comprised of four elements: the grooved pipe, the gasket, the coupling housing, and the nuts and bolts. The groove is made by cold forming or machining a groove into the pipe ends. A gasket encompassed by the coupling housing forms a seal on the two pipe ends, and the key sections of the coupling housing engage the grooves. The bolts and nuts are tightened with a socket wrench or impact wrench. In the installed state, the coupling housing encases the gasket and engages the grooves around the circumference of the pipe to create a leak-tight seal in a self-restrained pipe joint. There are two basic coupling styles that can be used on grooved pipe: flexible and rigid.

Benefits of Grooved Piping System

Coupling Housing Segment

A flexible coupling accommodates pipe deflection and or non-alignment as below : if nominal diameter 1;If nominal diameter>Dn200, deflection angle is >0.5 but<1

Gasket

With the removal of just a few bolts, you can easily access the system for cleaning maintenance, change or system expansion

Coupling Housing Segment

The C-shaped rubber gasket provide excellent self-sealing capabilities in both low and high pressure service as well as under certain vacuum conditions.
Coupling are non-directive and pipe can be rotated 360 during installation

Coupling Housing Segment

Coupling keys engage the full circumference of the grooves and provide significant pressure and end load restraint pipe movement from internal and exernal forces.

Bold/Nut

The design and construction of the coupling with elastomeric gaskets can provide significant noise and vibration absorption as well as seismic stress.
