ABSTRACT:
A method and apparatus for determining position size and shape of defects in a bundle of heat exchanger tubes are described. An AC current exciter coil is placed in one tube and a detector coil is placed in an adjacent tube. This configuration of exciter and detector coils reduces the blind spot effect caused by interference by tube support plates and allows the inspection multiple or finned heat exchanger tubing.
