What is the method?
Tank Bottom Testing using Magnetic Flux Leakage (MFL) is a scanning method used to inspect ferromagnetic storage tank bottom plates for corrosion-related metal loss.
Application
Tank Bottom Testing using Magnetic Flux Leakage (MFL) is a scanning method used to inspect ferromagnetic storage tank bottom plates for corrosion-related metal loss.
Key Benefits
- Rapid scanning of large tank floor areas.
- Effective for locating corrosion-prone regions.
- Supports repair planning and outage optimisation.
- Useful for baseline and repeat monitoring.
Inspection Capabilities
- Specifically designed for efficient inspection of large tank floor areas.
- Particularly good at locating corrosion patterns, pitting clusters, and underside floor deterioration.
- Helps direct targeted UT verification and repair planning during tank turnarounds.
- Strongly supports storage tank integrity programmes (API 653) and floor condition screening.
Limitations
- Primarily a screening and mapping tool.
- UT verification is generally required for remaining thickness confirmation.
- Limited to ferromagnetic tank floors.
- Surface condition and welds can affect data quality.
