Magnetic Flux Leakage (MFL)
Magnetic Flux Leakage (MFL) is a nondestructive examination technique that uses electromagnetism to inspect for flaws or material degradation in steel structures. In the oil and gas industry, it is often used to search for flaws in piping and pipelines, as well as aboveground storage tank floors. MFL uses magnets to temporarily magnetize the structure. If there are flaws present, the magnetic field created will show distortions, signaling the presence of things like corrosion, pitting, and wall loss.

The development of advanced NDE techniques/tools is one of the reasons the inspection trade has taken significant steps forward in the last couple decades; and the advancements appear to be accelerating. One of the many ways to keep up with advancing NDE technology is to attend the semi-annual NDE task group meetings at the Spring and Fall API Refining and Equipment Standards Meetings. In fact, that T/G is planning to document many of the advanced NDE...
