Pulse Eddy Current Testing – Corrosion under insulation (CUI)

Eddy Current Testing (ET) is mainly used for surface crack detection on metallic materials, but also to detect corrosion on thin materials. The main advantage compared to MT and PT, which also detect surface cracks, is that it can test trough 1-2mm of coating. Eddy Current is a highly sensitive tool that provides quick results with minimum preparation.

Pulsed eddy current testing has been developed to detect corrosion hidden under insulation. ESNADVB provides a PECT services using the latest NDT equipment.

Typical applications:

• Corrosion under insulation
• Corrosion under fireproofing (CUF)
• Detection and sizing of flow-accelerated corrosion (FAC)
• Inspections in the splash zone – through coatings, marine growth and corrosion product
• Wall thickness monitoring and inspection through repair wraps
• Defect assessment through corrosion product
