Protecting Critical Assets During High-Velocity Steam Blows: Don't Let Thermowell Failure Destroy Your Steam Blow Schedule
Microscopic vibrations you can't predict can cost you weeks of delays. Learn how to protect critical instrumentation during high-velocity steam blows—and why the industry's leading EPCs trust FQE Power's thermowell vibration analysis expertise.
The Hidden Risk in Your Steam Blow Plan
In three decades of commissioning power plants, we've witnessed a consistent pattern: perfectly engineered steam blow programs compromised by unanticipated thermowell failures.
High-velocity steam blows demand extreme flow conditions to achieve effective cleaning. Yet thermowell vibration remains one of the most under-recognized—and potentially costliest—risks to successful commissioning.
The consequences are severe:
- Equipment damage from failed thermowells impacting downstream components
- Schedule delays while you assess damage, replace instruments, and restart operations
- Safety concerns for personnel and surrounding equipment
- Lost confidence from EPCs, owners, and OEMs questioning your risk management
One overlooked thermowell. One resonance condition. One vibration-induced failure. That's all it takes to halt your steam blow program and derail your commissioning timeline.
Why This Matters Now
After the tragic 1995 MONJU Nuclear Power Plant incident—where thermowell vibration failure caused a major sodium leak and fire—ASME revised its standards in 2010 to address flow-induced vibration and cyclic stress contributions to thermowell failure.
EPCs and equipment manufacturers now demand documented proof that thermowells will survive steam blow conditions. The industry needed a comprehensive engineering solution.
FQE Power pioneered that solution.
This comprehensive white paper represents 30 years of field-proven expertise in steam blow engineering and fluid dynamics, distilled into actionable strategies you can implement immediately

What This White Paper Will Do For Your Project
For EPC Contractors:
- Eliminate thermowell failure as a source of steam blow delays
- Provide documented ASME PTC 19.3 TW-2010 compliance for all stakeholders
- Reduce liability exposure through proactive engineering analysis
- Implement defensible risk mitigation protocols your team can trust
For Commissioning Manager:
- Understand the physics behind thermowell vibration (with calculations you can verify)
- Identify at-risk installations before steam blows begin
- Implement practical mitigation measures—removal, reinforcement, or operational adjustments
- Maintain your critical path schedule with confidence
For Plant Owners:
- Protect your instrumentation investment from vibration damage
- Ensure safe, effective steam blow operations from day one
- Avoid catastrophic delays from unanticipated thermowell failures
- Gain documented assurance for insurance and warranty purposes
The Cost of Waiting
Every day you delay addressing thermowell vibration risk is a day closer to discovering a failure during steam blows—when it's exponentially more expensive to fix.
Consider the math:
- Pre-blow analysis and mitigation: Minimal engineering cost, integrated with existing planning
- Mid-blow thermowell failure: Days to weeks of delays, equipment damage assessment, instrument replacement
- Post-failure consequences: Extended commissioning timeline, stakeholder confidence loss, potential safety incidents
The question isn't whether you can afford to implement proper thermowell vibration analysis.
The question is: Can you afford not to?
