Abstract
The application of eddy current testing for structural integrity assessment of heat exchangers is a well established practice. Service induced multiple defects in heat exchanger tubes produce difficult-to-evaluate complicated impedance plane trajectories during periodic eddy current examinations. Finite element simulations carried out to analyse interactions in a two-defect system are discussed. Probable uncertainty in the interpretation of eddy current trajectories is highlighted. Systematic analysis of the results from these studies will simplify procedures for on-line evaluation of eddy current signals.
