Quantification of Complex Defects in Magnetic Flux Leakage (MFL) Testing Using Gradient Gray Level Analysis Based on Least Square Approximation

2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019
Knowing that realistic defects in materials are not simple but complex which influence inspection results, it is most important that the NDT/E of materials provide quantitative information of defects such as size, length, depth and orientation so as to accurately and efficiency predict a structures integrity and lifespan.

Testing of a Dual Field Magnetic Flux Leakage (MFL) Inspection Tool for Detecting and Characterizing Mechanical Damage Features

2008 7th International Pipeline Conference, Volume 2, 2008
Battelle has developed dual field magnetic flux leakage (MFL) technology for the detection and characterization of mechanical damage to pipelines. The basic principle involves the use of a high magnetic field between 140 and 180 Oersted (11.1 to 14.3 kA/m) and the use of a low magnetic field between 50 and 70 Oersted (4 to 5.6 kA/m).

Simulation Analysis of Magnetic Flux Leakage (MFL) Testing for Wire Rope Based on Multilayer Helical Structure

Using finite element simulation analysis, different wire rope structures with the same diameter and damage models were created for analyzing the principle of magnetic flux leakage (MFL) wire rope inspection. As a result, different wire rope modelling structures result in different distributions of the internal magnetic field within the wire rope as ...
