Magnetic Flux Leakage (MFL)Magnetic flux leakage (MFL) is an electromagnetic non-destructive testing technique used to detect corrosion and pitting.DetailsHow it Works MFL uses a powerful magnet to magnetize the conductive material under test (usually steel). Where there are defects — corrosion or...
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.Magnetic flux leakage...
Magnetic flux leakage (MFL) is commonly used for inspecting tank floors in the petrochemical industry. Corrosion of the tank floor can lead to the loss of product and cause damage to the environment. Therefore, it is vital that tank floor inspections are carried out in order to prevent the ...
Magnetic Flux Leakage (MFL) is an NDT technique commonly used to inspect for wall loss and sharp defects such as pitting, grooving, and circumferential cracks.
We consider the application of the magnetic flux leakage (MFL) method to the detection of defects in ferromagnetic (steel) tubulars. The problem setup corresponds to the cases where the distance from the casing and the point where the magnetic field is measured is small compared to the curvature...
A magnetic field is induced in a steel plate from the magnetic poles of the yoke (i) and is tuned to a strength where the magnetic flux (ii) saturates a steel plate of uniform thickness (iii). The presence of material loss (simply referred to here as ‘defect’) (iv) produces a mag...
1.1 Magnetic Flux Leakage (MFL) technology has been used in the monitoring of Underfloor or Far Side (FS) corrosion for about 11 years. Silverwing (UK) Ltd entered the field ten years ago, in 1991. As with all Non Destructive Testing methods, MFL has both advantages and disadvantages,...

The magnetic flux leakage (MFL) measurement method is a non-destructive and contactless method for the inspection of the tendons of pre-stressed concrete structures. This chapter describes the basics of the MFL as well as the procedures of the signal analysis. Examples of on-site investigations ...
7.4 Magnetic flux leakage (MFL) pigs MFL pigs were first introduced in the mid 1960s. Since then, in-line inspection capabilities have evolved, and they continue to evolve today. MFL is the oldest and most commonly used inspection method for pipelines. It can reliably detect metal loss due ...
