Magnetic flux leakage (MFL) is an electromagnetic non-destructive testing technique used to detect corrosion and pitting.

Magnetic flux leakage (MFL) is commonly used for inspecting tank floors and Ferromagnetic tubes in the petrochemical industry.

Magnetic Flux leakage technology operates in a principle that a powerful magnet is used to magnetize the steel and the magnetic detector detects the corrosion or material loss which leaks the magnetic field from the steel and then further analyzed to determine the location and severity of the defect. In an MFL tool, a magnetic detector is placed between the poles of the magnet to detect the leakage field.

InterTech offers both tube and tank inspection by Magnetic Flux Leakage Technique with renowned state-of-the art equipment.
