We’ve found evidence of corrosion under insulation (CUI) on some HRSG components.
What are the best practices for detecting and preventing CUI?
Use moisture detectors to identify areas of trapped water under insulation. It’s an easy first step before full inspections.
Switch to insulation materials with hydrophobic properties. They’re better at repelling water and reducing CUI risks.
Conduct regular visual inspections during outages. Focus on areas near joints and supports where moisture tends to accumulate.
