Abstract

The possibility is shown of creating a chart of local corrosion damage in the walls of heat-exchange tubes on the basis of the data of matrix eddy current testing with registration of the position, type, and depth of all local corrosion damage areas. The results of examination of condensers operated under different conditions and at different plants are used to calculate the theoretical depth distribution of defects. It is shown that, in all cases, a satisfactory statistical description of the corrosion defect depth on the cooling water size is obtained by employing the Weibull distribution. Pearson’s coefficient is in the range of 0.994–0.997.
