Expert Repair & Failure Analysis

What Usually Goes Wrong

Body Cracking (Thermal Fatigue): Valve body develops cracks from repeated thermal cycling (startup/shutdown). Most common in main steam gate valves and feedwater check valves. Can lead to catastrophic failure if undetected.

Repair: NDE inspection (UT, MT, PT) to map crack extent. Weld repair if cracks are shallow and in non-critical areas. Body replacement if cracks penetrate >50% wall thickness. Lead time: 4-12 weeks depending on severity.

Backseat Leak: Backseat fails to seal when valve is fully open, allowing packing to be pressurized. Prevents online packing replacement. Common in older Edward gate valves.

Repair: Re-machine backseat in-situ or remove valve for shop repair. Backseat lapping requires specialized tooling. Lead time: 2-4 weeks.

Repair Lead Time

Cryogenic valve repair: 4-8 weeks — special materials, helium leak testing
