【漏磁】漏磁检测技术(MFL)的英文全称是什么?

网友回答

【答案】 MFL=Magnetic Flux Leakage:
　　英文说明:
　　Magnetic flux leakage (MFL) is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures,most monly pipelines and storage tanks.The basic principle is that a powerful magnet is used to magnetize the steel.At areas where there is corrosion or missing metal,the magnetic field leaks from the steel.In an MFL tool,a magnetic detector is placed between the poles of the magnet to detect the leakage field.Analysts interpret the chart recording of the leakage field to identify damaged areas and hopefully to estimate the depth of metal loss.This article currently focuses mainly on the pipeline application of MFL,but links to tank floor examination are provided at the end.
