State-of-the-Art RFT— Meeting the Ferromagnetic Tube Challenge

Ferromagnetic heat exchanger tubing found in petrochemical plants cannot be inspected with conventional eddy current techniques. Common inspection methods for this material include IRIS, magnetic flux leakage (MFL), and remote-field testing (RFT). In general, RFT is preferred due to its defect sizing capabilities, decreased need for tube cleanliness, and high inspection speeds. Although the RFT … Continue reading State-of-the-Art RFT— Meeting the Ferromagnetic Tube Challenge
