Zusammenfassung:JFE Engineering has developed a unique non-destructive stress measuring method using a magnetic anisotropy sensor and various evaluation systems applying this technology. This paper describes the principle of the stress measuring method and the experimental results which demonstrate the usefulness of the method in evaluating the stress levels in linepipes under working conditions for maintenance purposes. The test pipe was an SCP150A pipe.
