    Back to the Basics: Tank Floor MFL Testing | Technical Guide
    Manual Magnetic Flux Leakage (MFL) scanning is a non-destructive testing method using handheld, magnet-based devices to detect corrosion and pitting on steel surfaces, specifically storage tank floors and pipelines. Operators, like with the MFE Mark IV or Silverwing Handscan, push the scanner to identify metal loss, often relying on alarms for real-time detection in hard-to-reach areas. 
    Key Aspects of MFL Manual Scanning: 
    • Technology: Uses strong magnets to saturate steel with magnetic fields. Corrosion or metal loss disrupts this field, which is detected by sensors.
    • Application: Ideal for inspecting tank floors, welds, joints, and pipes.
    • Operation: The scanner is manually moved across the surface. Devices like the MFE HandScan often feature real-time displays that alert the user to potential defects via audio/visual alarms.
    • Data Analysis: Manual scanners can display signals in real-time, often highlighting channels (e.g., 1-12) to pinpoint corrosion, according to MFE Enterprise and Troy-Met.
    • Verification: Identified defects are typically marked and further analyzed using secondary methods such as Ultrasonic Testing (UT).
    • Equipment Examples:
      • MFE Mark IV/Mark III: Known for high maneuverability, 12-inch scan width, and fast, accurate results.
      • Silverwing HandScan: Specialized for small-scale, localized, or "dead" areas in tanks. 
    Benefits: 
    • Fast Inspection: Allows for quick, efficient, and cost-effective scanning of large areas.
    • No Surface Preparation: Requires minimal, if any, cleaning or coating removal.
    • High Sensitivity: Capable of detecting bottom-side corrosion that is not visible from the top.

    What is the difference between MFL and UT?
    MFL pigs are particularly useful in detecting volumetric metal loss and are less sensitive to contaminants inside the pipe. Ultrasonic pipeline inspection, on the other hand, provides more precise measurements of wall thickness but requires a liquid coupling medium, such as oil or water, to transmit sound waves.Aug 7, 2025

    What is the MFL procedure?
    To magnetize the steel, a powerful magnet is used. In an MFL (or Magnetic Flux Leakage) tool, a magnetic detector is placed between the poles of the magnet to detect the leakage field. Analysts interpret the chart recording of the leakage field to identify damaged areas and to estimate the depth of metal loss.
