Tank Floor Mapping (MFL)

Overview

Tank Floor Mapping (MFL)

Tank Floor MFL scanning is a non-destructive examination method which uses a magnetic field to detect corrosion and pitting. A powerful magnet is scanned close to the surface to ‘saturate’ the steel with the magnetic field. The scanner is moved over the entire tank bottom surface to provide the required inspection coverage. Technicians interpret the scanner display to identify damaged areas and in some cases, estimate the amount of metal loss. Thickness losses detected by ultrasound are reported and mapped in a CAD rendering of the floor.

Advantages:

  • Fast method for inspecting large areas
  • Minimal set-up time
  • Yields reliable and economic qualitative tank floor assessments. High sensitivity: acceptable sensitivity can be obtained through up to 0.500” of combined steel and coating thickness
  • Requires access to only one side of the material
