The Applied Technical Services Family of Companies (ATS FoC) conducts corrosion under insulation (CUI) inspections to detect hidden signs of corrosion or damage beneath the insulation on piping systems, vessels, tanks, and process equipment.
When moisture penetrates damaged insulation systems and becomes trapped beneath metal surfaces, corrosion can go undetected until leaks or failures occur. Proactive CUI inspections can help operators prevent leaks, unplanned downtime, and critical asset failures.
What Type of Nondestructive Testing (NDT) Is Used during CUI Inspections?
ATS uses advanced NDT methods to assess asset condition and remaining service life. Our CUI inspections follow API RP 583, API 570, API 571, and NACE SP0198/AMPP guidance to support informed corrosion management and asset integrity decisions.
Our NDT team uses methods such as:
- Pulsed Eddy Current (PEC)
- Real-Time Radiography (RTR)
- Ultrasonic Thickness Testing (UTT)
- Guided Wave Testing
- Infrared Thermography
- Visual Inspection (VT)
- Radiometric Profiling

What do CUI Inspectors Look For?
During corrosion under insulation inspections, our experts assess any indications of degradation that may have seeped into an insulation system due to rain, condensation, or spillage. Inspectors typically look for:
- External Corrosion Beneath Insulation
- Wall Loss or Wall Thinning
- Breaks in Jacketing
- Pitting Corrosion
- Stress Corrosion Cracking
- Moisture Intrusion Points
- Damaged Insulation
- Coating Deterioration
- Future Corrosion Risk Areas
Supporting Long-Term Corrosion Control
The ATS FoC has been a trusted partner in the testing, inspection, certification, and certification (TICC) industry since 1967. From oil and gas to pipelines and power generation, asset-intensive industries rely on ATS for corrosion management. Our state-of-the-art labs and advanced equipment are supported by an ISO 9001:2015-registered quality management system and multiple ISO/IEC 17025:2017 accreditations. Since joining SGS in 2026, we have expanded our NDT services to support clients across industries worldwide.
