Corrosion Under Insulation Enabling Risk-Based Inspection
As an industry leader for advanced NDT, NDE Solutions undertakes corrosion under insulation (CUI) for enhanced risk-based inspection (RBI).
We train and mentor our local personnel, whilst building partnerships with leading technology manufacturers such as evoSonic, Eddyfi & Guided Ultrasonics Ltd (GUL)…
Our Difference
Deploying an arsenal of advanced methods, NDE offers a one-stop shop for CUI campaigns using the below techniques.
- Pulsed eddy current (PEC) provides quick, efficient & repeatable inspection, capable of inspecting up to 30m of piping per shift via rope access.
- Open vision is a real time radiography technique which enables access to challenging areas such as pipe supports, with instant assessment.
- Long Range Ultrasonic Testing (LRUT) is capable of inspecting substantial distances from a single point of access. This technology is an efficient method for buried piping and not easily accessible lines.

CUI is a difficult corrosion mechanism to detect with no single non-destructive testing (NDT) method able to provide complete detection capabilities or application. Estimated remediation & inspection campaigns for CUI across complex asset industries are financially costly for operators.
Historical methods of inspection have been to remove large portions of cladding to complete conventional methods. This effectively results in 50% of integrity budgets being spent before any inspection data is captured or remediation has begun.
- Digital radiography (DRT) provides accurate and clear imagery for dead legs and small-bore fittings which are prone To CUI. DRT is a reliable method to assess integrity under insulation.
- Corrosion under pipe supports (CUPS) In partnership with GUL and other like-minded technology providers, NDE is able to deliver unrestricted circumferential & axial integrity information for pipe supports. Not one inspection method can meet all the challenges of CUI. However, our integrated and broad ranging suite of inspection solutions, allows NDE to safeguard your critical assets.
