Water hammer mitigation after a 280-bar surge incident: lessons from the field

A pressure surge event that destroyed two check valves and deformed a 14-inch header. Sequence of events, root cause, and the surge suppressor specification that came out of the incident review.

• Transient event reconstruction and pressure trace analysis
• 1D method-of-characteristics and 3D CFD model comparison
• Failure mode identification and root cause determination
• Surge suppression specification and system protection design
