The Applied Technical Services and our Family of Companies (ATS FoC) provide organizations with a robust corrosion under insulation (CUI) program to help identify corrosion risks early, prioritize inspections, and support long-term asset integrity. Our proactive CUI program enables facility owners and manufacturers to target high-risk assets and implement mitigation strategies before failures occur.
CUI occurs when moisture becomes trapped against metal surfaces beneath insulation, leading to hidden corrosion. Left unchecked, it can result in wall loss, leaks, environmental releases, costly repairs, and unplanned downtime.
What Does Your Corrosion Under Insulation Program Offer?
At ATS, our CUI program offers a structured, risk-based approach to identifying, assessing, and managing corrosion risks. By evaluating asset condition and prioritizing inspections, these programs help support proactive maintenance decisions.
Our CUI program includes:
- Asset inventory and criticality assessments
- Risk-based inspection (RBI) methods
- CUI susceptibility evaluations
- Inspection planning, scheduling, and prioritization
- Nondestructive testing (NDT)
- Data collection and reporting
- Ongoing degradation monitoring
What NDT Methods Apply to Corrosion Under Insulation (CUI) Inspection Programs?
ATS enables clients to assess insulated assets with minimal insulation removal and operational disruption. Our inspectors target the most corrosion-prone areas using advanced NDT methods, such as:
- Pulsed Eddy Current (PEC)
- Guided Wave Testing
- Infrared Thermography
- Visual Inspection (VT)
- Real-Time Radiography (RTR)
- Ultrasonic Thickness Testing (UTT)
Our corrosion under insulation program aligns with industry standards, including API RP 583, API 570, API 571, AMPP/NACE SP0198 and the applicabale ASTM standards and ASME codes.
