Magnetic Flux Leakage (MFL) technology has been widely used for pipeline inspection due to its reliability in detecting metal loss. However, unidirectional axial (MFL-A) and circumferential (MFL-C) tools have inherent limitations in detecting and sizing complex corrosion anomalies. These limitations often result in conservative reporting, increased...

Calculation of a laser-scan-like 3D defect profile from conventional MFL data – For more-accur ate defect assessment and prediction of safe operating pressure. Reliable pipeline safe pressure prediction is increasingly required. Complex shaped volumetric metal loss is a challenge in this regard. Methodological In-line Inspection (ILI) restrictions...
