Tube Inspections (IRIS, ECT, MFL, RFT)

Heat Exchanger Tube Inspection Techniques

Tubes can be inspected periodically to detect and size discontinuities e.g. pits, erosion, cuts, grooves and wear. Correct technique selection is critical and depends on the tube material (ferromagnetic or non-ferromagnetic) and the type of discontinuities expected.

• ECT – Eddy Current Testing
• RFT – Remote Field Testing
• NFT – Near Field Testing (Fin Fan Testing)
• IRIS – Internal Rotary Inspection System.
• MFT – Magnetic Flux Leakage Testing
