Magnetic Flux Leakage (MFL)

Rapid Inspection of pipes and storage tank floors for the Detection of corrosion and Erosion. MFL technology is similar to Magnetic Particle Inspection (MPI) but without the ink or magnetic particle. The component is magnetised to a level at which the presence of a significant local reduction in material thickness causes sufficient distortion of the internal magnetic field to allow flux lines to break the test surface at the site of the Discontinuity. With MFL, suitable sensors are used to give an electrical signal at the leakage site. This signal may operate an audible or visual alarm to alert the inspector, or may store the Event for computer mapping of the area. The floor map inspection equipment utilises magnetic flux leakage to detect top and bottom surface corrosion pitting
