"PSEC or magnetic bias eddy current tube testing is like RFT used for inspection of ferromagnetic heat exchanger and boiler tubes."

PSEC or magnetic bias eddy current tube testing is like RFT used for inspection of ferromagnetic heat exchanger and boiler tubes. The technology is based on ECTT. Whit the difference that PSEC probes are mounted with electromagnets powered by a DC generator to saturate tube wall. This brings back the relative permeability close to that of a non-ferromagnetic tube material. PSEC is a very fast and sensitive electromagnetic testing technique with detection capabilities close to ECTT. It is more sensitive to small pitting than RFT, but less appropriate for general wall loss detection and depth evaluation.

TÜV AUSTRIA proposes in-situ examination according ISO and ASME standards. Approximately 350, 6-meter-long tubes can be inspected in one normal working day. As secondary technique, IRIS or endoscopy are mostly proposed. All data is saved, and a report is generated the same day.
