Modeling of Magnetic Flux Leakage Measurements of Steel Pipes

摘要

Using commercially available magnetic modeling software we have modeled the signal of Magnetic Flux Leakage (MFL) testing of steel pipes with different types of defects, including inside, outside and tilted notches in 2D. The results presented here show interesting dependencies of signal amplitude and width on the defect geometry, which may be useful for defect separation. The implemented method can easily be adopted for different testing geometries and pipe materials.
