Magnetic Flux Leakage (MFL)

Magnetic flux leakage (MFL) is a magnetic method of non-destructive testing that is used to detect corrosion, pitting and wall loss in steel structures.

Magnetic flux leakage (MFL) is commonly used for inspecting tank floors in the petrochemical industry. Corrosion of the tank floor can lead to the loss of product and cause damage to the environment. Therefore, it is vital that tank floor inspections are carried out in order to prevent the occurrence of such problems.

The method uses permanent or electromagnets to magnetise the tank floor and the resulting magnetic field changes are recorded and analysed. If there is corrosion, pitting or wall loss, the magnetic field ‘leaks’ and the ‘leakage’ is analysed to determine the location and severity of the defect of the tank floor – both near and far surface.
