Experiment and simulation study of 3D magnetic field sensing for magnetic flux leakage defect characterisation

, 2007
Magnetic flux leakage (MFL) testing is widely used to detect and characterise defects in pipelines, rail tracks and other structures. The measurement of the two field components perpendicular to the test surface and parallel to the applied field in MFL ...

Quantitative assessment of pipeline defects utilizing a dual-stage deep learning framework: Integration of pretrained YOLO network and multi-input parallel convolution architectures on magnetic flux leakage data

Journal of Pipeline Science and Engineering
As long-distance oil pipelines near the end of their operational tenure, the propensity for leakage due to localized defects markedly increases, necessitating the imperative for systematic inspection and sustained maintenance efforts.
