An Introduction to Grooved Piping Systems: Speed, Flexibility, and Vibration Dampening
1. The Grooved Concept Instead of welding or threading, a groove is rolled or cut into the end of the pipe. A Grooved Coupling (containing a C-shaped gasket) is then bolted over the two pipe ends to create a seal.
2. Rigid vs. Flexible Couplings
- Rigid Couplings: Create a joint that behaves like a welded connection, allowing no movement.
- Flexible Couplings: Allow for a small amount of angular deflection and axial movement, making them perfect for earthquake zones or high-vibration pump rooms.
