The Applied Technical Services Family of Companies (ATS FoC) provides corrosion under insulation (CUI) testing to detect concealed evidence of corrosion damage beneath the insulation on vessels, piping systems, tanks, and process equipment.
When moisture penetrates damaged insulation systems and becomes confined beneath metal surfaces, corrosion can go undetected until leaks or failures occur. Proactive CUI inspections can help operators avoid unplanned downtime, prevent leaks, and critical asset failures.
How Can I Inspect Piping Systems Without Removing Insulation?
ATS can inspect insulated piping systems without removing insulation using our comprehensive nondestructive testing (NDT) methods, such as:
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
These non-invasive methods can help identify hidden corrosion or wall loss while minimizing operational downtime.
What Standards Apply to Corrosion Under Insulation (CUI) Inspection Programs?
Our corrosion under insulation (CUI) testing programs typically follow relevant NDT standards, as well as:
- API RP 583
- API 570
- API 571
- AMPP NACE SP0198
- ASTM and ASME
These testing standards guide our approach to identifying CUI risks, inspecting insulated assets, and evaluating damage mechanisms. By applying these methods, we help you mitigate risks and improve asset reliability and safety.
