Abstract
The results of industrial application of a matrix eddy-current probe in studying local corrosion in heat-exchanger tubes are considered. Local corrosion of several heat exchangers that were used under various conditions has been analyzed by eddy-current techniques. Statistical analysis has confirmed the effect of polymer coatings on local corrosion suppression and prevention. Using an original eddy-current probe, the rate of scale formation on the tubes of a thermal power station condenser has been measured for heat-exchanger tubes that were protected from inside by a polymer coating.
