- Magnetic Flux Leakage (MFL) is an advanced nondestructive testing (NDT) technique commonly used in the oil & gas and chemical processing industries to inspect for wall loss and sharp defects such as pitting, grooving, and circumferential cracks in ferromagnetic materials (most commonly pipelines and storage tanks).
- Magnetic flux leakage is commonly used for inspecting pipelines and storage tanks in the oil & gas industry; however, the technique can be applied to assets in other industrial sectors. In fact, MFL is the oldest and most commonly used ILI technique for pipelines due to its ability for reliably detecting—while the pipelines are in service—internal and external metal loss due to corrosion. MFL is also widely used for detecting flaws and corrosion in above ground storage tank floors.
