  • Rotating magnet-induced current pipeline inspection tool and method
    Publication number: 20060164091
    Abstract: Disclosed are an apparatus and method for integrity monitoring of tubular components and, in particular, pipe walls. The apparatus comprises a configuration of permanent magnets arranged to rotate circumferentially within the pipe, whereby uniform low-frequency currents are generated within the pipe wall which, in turn, generate fields detectable with, for example, conventional Hall Effect sensors. The method comprises steps to rotate the apparatus within the pipeline and sense disruptions caused by anomalies in the pipe wall.
