The Ultimate Guide to Selecting Grooved Couplings for Fire Protection Systems
Learn how to choose the right rigid and flexible grooved couplings for high-pressure fire pipeline installations.
In fire protection engineering, selecting the correct grooved couplings is critical to insuring safety and pipeline longevity. Today we will break down the fundamental differences between rigid and flexible couplings.
1. Rigid Couplings vs. Flexible Couplings
Rigid couplings provide a completely tight joint, meaning the pipe behaves like a continuous line. This is ideal for straight runs where no movement is expected. Flexible couplings, on the other hand, allow for angular deflection and thermal expansion.
2. Industry Standards
Always ensure your grooved fittings carry FM approval and UL listing certificates before deploying them in official fire-fighting projects.
