SYSTEM AND METHOD FOR DETECTING SELECTIVE SEAM WELD CORROSION IN A CONDUIT BASED ON MAGNETIC FLUX LEAKAGE MEASUREMENTS

摘要

Embodiments relate to a system and method for detecting and remediating selective seam weld corrosion in conduits such as steel pipes that transport oil and gas products. In particular, a probe detects magnetic flux leakage in at least two orientations. Anomalies in the conduit are then identified and assessed for selective seam weld corrosion based on factors that include the magnetic flux leakage detection and the depth of the anomalies. For certain categories of assessed anomalies, the corresponding portions of the conduit are selectively remediated in accordance with these factors.
