Magnetic Flux Leakage (MFL) Testing

What is Magnetic Flux Leakage Testing? 

Magnetic Flux Leakage (MFL) Testing is an advanced non-destructive testing (NDT) technique used to detect corrosion, pitting, and other defects in ferromagnetic materials. This method relies on powerful magnets to induce a magnetic field in the tested component. When flaws are present, they cause distortions in the magnetic field, which are detected by highly sensitive sensors. These signals are interpreted to provide an assessment of the material’s defects. 

Industries such as oil and gas, petrochemicals, power generation, and transportation depend on magnetic flux leakage testing to evaluate pipelines, storage tanks, and pressure vessels. Dexon Technology’s cutting-edge MFL solutions help operators maintain asset integrity, prevent failures, and comply with industry standards. 

Common Problems and How Magnetic Flux Leakage Testing Provides Solutions 

Ferromagnetic material degradation can result in significant operational and safety concerns, including: 

• Undetected Corrosion and Wall Loss: Gradual metal loss can weaken structures, leading to potential failures. 

• Pipeline and Tank Integrity Risks: Corrosion and pitting can compromise containment systems, leading to leaks or catastrophic failures. 

• Limited Detection Capabilities of Conventional Methods: Some traditional NDT techniques may miss subsurface flaws or small pits. 

• Regulatory Non-Compliance: Industries require periodic integrity assessments to meet ASME, API, and ISO standards. 

Magnetic flux leakage testing addresses these challenges by: 

• Detecting Subsurface and Surface Defects: Provides a highly sensitive assessment of wall thinning and corrosion. 

• Increasing Inspection Speed: Allows for rapid, large-scale assessments of pipelines and tanks. 

• Enhancing Defect Characterization: Differentiates between localized corrosion, pitting, and general material loss. 

• Supporting Preventative Maintenance Programs: Enables early detection of defects, reducing unplanned repairs and operational downtime. 

By incorporating magnetic flux leakage testing into routine maintenance and integrity programs, Dexon Technology helps clients optimize performance, improve safety, and extend the lifespan of assets.
