Abstract
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.
Claims20
A system for detecting selective seam weld corrosion in a conduit, comprising,
- a probe, the probe constructed to traverse at least a segment of the interior of the conduit and comprising sensors capable of detecting magnetic flux leakage in at least a first and second orientation in proximity to a conduit seam of the conduit;
- a probe processor, the probe processor creating at least one dataset, the at least one dataset based on detection of magnetic flux leakage in the first and second orientation;
- one or more predictor processors in communication with one or more memory devices, the one or more memory devices containing computer-readable instructions that, when executed by the one or more predictor processors, can operate to:
- receive the dataset;
- identify, from the dataset, a portion of the conduit containing an anomaly;
- analyze the anomaly to determine the presence of selective seam weld corrosion by operating to:
- a) compare the dataset with a reference dataset containing data indicative of selective seam weld corrosion, and
- b) determine whether aspects of the dataset are within parameters indicative of selective seam weld corrosion;
- and
- generate an alert status corresponding to the anomaly, wherein the alert status is indicative of potential selective seam weld corrosion within the portion of the conduit and is determined by results from the analysis of the anomaly.
A system for detecting selective seam weld corrosion in a conduit, comprising one or more predictor processors in communication with one or more memory devices, the one or more memory devices containing computer-readable instructions that, when executed by the one or more predictor processors, can operate to:

- b) determine whether aspects of the dataset are within parameters indicative of selective seam weld corrosion;
- and
- generate an alert status corresponding to the anomaly, wherein the alert status is indicative of potential selective seam weld corrosion within the portion of the conduit and is determined by results from the analysis of the anomaly.
A computer-implemented method for systematically detecting selective seam weld corrosion in a conduit, comprising,
- receiving a dataset, the dataset containing information obtained from a probe traversing at least a segment of the interior of the conduit and detecting at least one of an electromagnetic, magnetic and sound-related occurrence from an area of the conduit in proximity to a conduit seam;
- identifying, from the dataset, a portion of the conduit containing an anomaly;
- analyzing the anomaly to determine the presence of selective seam weld corrosion by at least one of:
- a) comparing the dataset with a reference dataset containing data indicative of selective seam weld corrosion, and
- b) determining whether aspects of the dataset are within parameters indicative of selective seam weld corrosion;
- and
- generating an alert status corresponding to the anomaly, wherein the alert status is indicative of potential selective seam weld corrosion within the portion of the conduit and is determined by results from the step of analyzing.
