Joining Method Grooved

Grooved pipe joints consist of two grooved pipe ends (typically roll grooved) connected with a coupling consisting of a pressure responsive elastomer gasket to create the seal and a ductile iron housing to encapsulate the gasket and lock into the grooves creating a self-restrained pipe joint. These connections have the advantage of being slightly flexible, enabling installation with less than perfect pipe alignment.

The grooved coupling installation process is relatively simple and requires only a hand ratchet or impact wrench. The benefits include increased installation productivity and elimination of flame and related safety precautions and risks over traditional methods.

Grooved pipe end preparation is fast and easy either in the shop or on the job site with a variety of grooving tools.

Rigid and flexible coupling types are available for specific applications. The majority of coupling applications require rigid couplings to allow the same supporting as traditional systems (ASME B31.1, .3 and .9).

Grooved systems are available for carbon steel and stainless steel pipe sizes up to 24” and wall thickness ranging from Schedule 5 through Schedule 40. They are also available for copper systems sizes through 8” and wall thickness of K, L, M and DWV.

Consult the manufacturers’ published literature for specific installation instructions and performance capabilities, as performance and requirements vary between manufacturers and coupling models/types.
