Simulation of magnetic flux leakage (MFL) analysis using FEMM software
2010 IEEE Symposium on Industrial Electronics and Applications (ISIEA), 2010Magnetic flux leakage (MFL) is a method used in oil and gas piping systems which has potential in medical gas piping inspection, cleaning and gauging tasks without interrupting the pipeline transportation process. MFL is a magnetic method of nondestructive testing that applies a magnet to magnetize the steel.

Almost all pipelines need constant monitoring and frequent inspections. This paper presents the design of a magnetizer assembly and experimental simulation investigation of flux leakage. The simulations carried out in a well known multiphysics software to get insights for the designed magnetizer assembly based MFL tool.

Abstract The standard evaluation methods for MFL-A inspections are based on simple calibration approaches that lead to stable results as long as the corrosion tends to be isolated and shallow. This paper presents a method suitable for complex and deep corrosion that utilizes FEM simulations on ultra-high resolution MFL-A data.

The stripping defect of rail top surface seriously affects the safety. In order to predict the accurate size of the defect, firstly, a rail MFL car with 3D- Magnetic sensor is designed, and rectangular pit defects are artificially manufactured on the rail. Permanent magnets are used to excitation the detection area of the rail.

PR-244-12700-R01 Effects of Stress on Casing Magnetic Flux Leakage (MFL) Measurements
2018Pipeline Research Council International (PRCI) contracted C-FER Technologies (1999) Inc. ("C-FER") to conduct a laboratory testing program to determine the Effects of Stress on Casing Magnetic Flux Leakage (MFL) Measurements. Tubing joints with localized defect features were subjected to increments in axial tension to maximum stress levels beyond ...

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).
