#408 – Rigid Coupling vs Flexible Coupling: When to Use Each
网页2022年6月21日 · Learn the differences between rigid and flexible grooved couplings, how they are used in fire sprinkler systems, and when NFPA 13 requires them for seismic protection. Flexible couplings allow some movement and space to prevent pipe damage in earthquakes, while rigid couplings are standard pipe joints.
