The usage of pipe grooved ends joints
A grooved end joint is a mechanical connection,which has no welding or thread.It’s fromed with a grooved-end pipes,fittings or valves,and a victualic coupling (or Equal).
The coupling comprises three parts:gasket,housings,and bolts nuts.
The grooved steel pipes and pipe fittings means the steel pipes or pipe fittings have a groove on the ends,the groove couplings are used to connect the grooved pipes and fittings.
The bolts and nuts are used to hold the housings together,they are tightened with a socket wrench or an impact wrench.The coupling housings engage the end grooves and encase the gasket around the circumference of the two pipes,it can bring a leak-tight seal in the pipe end joint.
There are two kinds of grooved coupling for different working conditions:
Flexible grooved couplings– allow a limited amount of angular movement.
Rigid grooved couplings– do not allow movement and can be used wherever immobility in the pipe joint is needed,similar to a flanged or welded joint.
The mechnical tees or cross also can be used to connect the grooved steel pipes and pipe fittings.
