NDT is an inspection or testing methods to evaluate properties, characteristics, quality or defects of a material, component or equipment in a system.

​

NDT methods are used in various industries such as oil and gas, automobile, nuclear, medical, aerospace...etc... NDT is applicable in both manufacturing and maintenance.

Magnetic flux leakage (MFL)

​

Magnetic flux leakage (MFL) is a magnetic method of nondestructive testing to detect corrosion and pitting in steel structures, for instance: pipelines and storage tanks. The basic principle is that the magnetic field "leaks" from the steel at areas where there is corrosion or missing metal. To magnetize the steel, a powerful magnet is used. 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 to estimate the depth of metal loss.
