Executive Industry Relevance

This protocol enables non-destructive relative thickness assessment of conductive ferromagnetic materials, supporting structural health monitoring in energy, water, oil, and gas infrastructure. By quantifying degradation such as corrosion and graphitization without requiring material-specific calibration, it facilitates early detection of integrity loss in large-diameter pipes. The method enhances predictive confidence in maintenance decisions and reduces operational risk in critical asset management workflows.
