Corrosion Under Insulation (CUI) Detection and Repair Techniques
During a routine assessment of an industrial tower's skirt area, disturbing evidence of corrosion behind the fireproofing was uncovered. Ultrasonic thickness testing revealed localized wall thickness reductions of up to 0.138 inches, exceeding the critical 70% threshold — triggering a comprehensive structural evaluation and repair plan.
