Corrosion and Corrosion Control
an endless battle against nature
Principle of Magnetic Flux Leakage (MFL) A magnetic flux leakage (MFL) inspection is the type of in-line inspection technology in which a magnetic saturation is induced in the pipe wall between two poles of a permanent strong magnet. The pipe…
