Remote field eddy current examination of heat exchangers
- Russell Technologies, Inc., Edmonton, Alberta (Canada)
Heat exchanger tubes can be examined for metal loss using remote field eddy current (RFEC). RFEC is an electromagnetic technique that produces a fast, economical, and thorough heat exchanger tube assessment. With RFEC services available, damaged tubes can be found and plugged, keeping heat exchangers operating near peak efficiency and reducing the risk of an unplanned shutdown. The technique is becoming well recognised in industry. RFEC uses a low-frequency field to penetrate ferromagnetic tube walls which are not practical to inspect with conventional eddy current. Internal and external metal loss is detected with nearly equal sensitivity. RFEC data from the field are presented with examples of different types of metal loss signals.
