RFT can detect and size all the typical defects in ferrous tubes—steam erosion, corrosion, baffle cuts, and pitting. Eddyfi® offers several RFT probes to measure wall loss, to size pitting, and to detect flaws hidden by support plates in feedwater heaters, heat exchangers, and piping.

Our single-driver boiler probes are equipped with spring-loaded centering devices that allow them maintain signal quality while leveraging their very high flexibility, often necessary in the tight bends found in boilers. The probes are also waterproof, making them perfect for submerged operation.
