Analysis of Magnetic-Flux Leakage (MFL) Data for Pipeline Corrosion Assessment

IEEE Transactions on Magnetics, 2020
Oil and gas pipelines transport and distribute large quantities of oil products and natural gas to industrial and residential customers over a long distance. However, pipeline failures could lead to enormous hazards and safety issues. Metal loss, due to corrosion, is a significant cause for pipeline failures.

Simulation of magnetic flux leakage (MFL) analysis using FEMM software

2010 IEEE Symposium on Industrial Electronics and Applications (ISIEA), 2010
Magnetic 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.

Study on the Magnetic Flux Leakage (MFL) for Fillet Weld

Advanced Materials Research, 2012
The magnetic flux leakage (MFL) technique is widely used as a Non-Destructive Testing (NDT) method for welds [1]. Because of the specialty of fillet weld structure, the defect may not be in the location suitably detected, which is normally at the center of yoke poles, and the rate of detect-ability would decline.

The interaction of multiple magnetic circuits in magnetic flux leakage (MFL) inspection

2014 IEEE Far East Forum on Nondestructive Evaluation/Testing, 2014
In this paper, a multi-magnetizer comprise of three units was introduced, of this multi-magnetizer, permanent magnet, poke, brush, and pipeline form a closed magnetic circuit in each unit, and each unite can be adjusted relative angle to meet the requirement for detection of pipes with different size. The investigation focuses on the interaction due to

A Defect Evaluation Methodology Based on Multiple Magnetic Flux Leakage (MFL) Testing Signal Eigenvalues

Research in Nondestructive Evaluation, 2015
This article is based on the associated linearity of magnetic flux leakage signal eigenvalues and detection status information, proposing a methodology that applies multiple magnetic flux leakage signal eigenvalues to evaluate defects and goes a step further in conforming the limitation of the traditional evaluation system, which merely uses signal ...

Enhancing Results of Ultra-High-Resolution Axial Magnetic Flux Leakage (MFL-A Ultra) Inspection Data Utilizing Finite-Element Modeling (FEM) Simulations

Volume 2: Pipeline and Facilities Integrity, 2022
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.
