UL FM Grooved Fittings

Speed of Installation: Installation is significantly faster than welding or threading. It involves simple steps: groove the pipe, place the gasket, position the coupling, and tighten the bolts. This can reduce labor costs by up to 50% compared to welded systems.

Safety: The process is much safer as it eliminates hot work (welding) and associated risks like fires and fumes. It also reduces ergonomic risks from heavy lifting and threading.

Flexibility: The system can accommodate thermal expansion, contraction, vibration, and seismic movement (when using flexible couplings), reducing stress on the pipes and equipment.

Modularity & Future Modifications: Systems are easy to modify, disassemble, and reassemble. Adding a branch line or moving equipment is far simpler than cutting and re-welding.

No Residual Stress: Unlike welding, which introduces heat and can warp pipes or leave stress points, grooving is a cold process that doesn't affect the pipe's metallurgy.

Allows for Misalignment: Flexible couplings can accommodate minor misalignments during installation.

Reduced Downtime: For repairs or modifications, the system can be taken apart and put back together quickly, minimizing system downtime.

Visual Verification: A properly installed joint is easy to inspect—if the coupling keys are fully engaged in the grooves and the bolts are tight, the joint is correct.
