MFL - Truflux Series

---

Magnetic flux leakage (MFL) is a magnetic method of non-destructive testing that is used to detect corrosion and pitting in steel structures, mainly in storage tanks and pipelines.

The basic principle is that a powerful magnet is used to magnetise the steel, where there are defects, the magnetic field "leaks" from the “damaged” steel areas and this “leakage can be measured.

Baugh and Weedon design and manufacture MFL Tank Floor Scanners, the TruFlux series, which are commonly used for the inspection of tank floors in the petrochemical industry. This is a critical point in asset management across the globe and the corrosion of tank floors can lead to the loss of “contained product”, which often has toxic or hazardous properties, causing damage to the environment.

Inspection data from MFL scanners can be analysed to see new and developing corrosion, pitting or wall loss, both in near and far surfaces, enabling predictive asset management and planned maintenance strategies.
