•A corrosion test for the tubes with different levels of eddy current noise was conducted.•A relationship between the corrosion rate and the eddy current noise of tubes was explored.•Corrosion rate was closely correlated to the tube noise of a rotating pancake probe.•Corrosion rate was not related to the tube noise measured using a bobbin probe.
The purpose of this work is to develop an eddy current testing method to predict the general corrosion behavior of Alloy 690 steam generator tubes. A corrosion test was conducted for tubes with different levels of eddy current noise in simulated primary water at 330 °C, and their corrosion behavior was correlated with the tube noise measured using bobbin and rotating probes. The corrosion behavior was closely correlated with the tube noise measured using a rotating probe. However, there was no correlation between the corrosion behavior and the tube noise measured using a bobbin probe. The tube noise value measured using a rotating pancake coil probe is suggested to be a significant parameter in estimating the general corrosion behavior of tubes.
