Service • Magnetic Flux Leakage (MFL)
Magnetic Flux Leakage (MFL) Testing
MFL is a fast, reliable screening method for detecting metal loss and surface-breaking defects in ferromagnetic components such as pipelines, storage tanks, and steel structures—supporting safer operations and better maintenance decisions.
What MFL detects (and why it matters)
MFL magnetises the test object and measures leakage fields caused by discontinuities. It is commonly used to identify corrosion/metal loss, pitting, and surface-breaking flaws on ferromagnetic materials.
Our team supports on-site deployment across Singapore, Malaysia, and the wider SEA region—helping you screen large areas efficiently and prioritise follow-up inspection where needed.
Where MFL is commonly applied
MFL is well-suited for rapid screening of ferromagnetic assets where metal loss and surface defects are key concerns. Typical applications include:
Pipelines & flowlines
Screen for corrosion, pitting, and external damage to help plan maintenance and integrity actions.
Storage tanks & vessels
Identify areas of metal loss on accessible surfaces to support repair planning and shutdown scope.
Steel structures
Detect surface-breaking defects and localised loss on ferromagnetic structural members.
Fabrication & QA screening
Support quality checks and condition assessment where fast coverage is required.
How we work
Our MFL inspection workflow
A practical, site-ready process designed to minimise disruption while delivering clear findings for decision-making.
1) Scope & access planning
Confirm asset type, material (ferromagnetic), surface condition, access constraints, and inspection objectives (screening vs targeted).
2) Setup & calibration
Select suitable MFL equipment and verify sensitivity using reference standards or agreed verification checks.
3) Scanning & data capture
Perform systematic scanning with controlled coverage to identify indications associated with metal loss or surface-breaking defects.
4) Review, verification & reporting
Interpret results, recommend follow-up methods where needed (e.g., UT thickness gauging), and issue a clear report with locations and prioritised observations.
