Intelligent defect recognition from magnetic flux leakage inspection
THIS paper presents a new approach for detection of oil-gas pipeline corrosion defects in which pipeline magnetic flux leakage (MFL) detection system is adopted. To test the new approach, some artificial defects are simulated mathematically on the surface of oil-gas pipes to simulate different defects happening in practice. The interference eliminating method is introduced for compensation of d...
متن کاملInfluence of Slot Defect Length on Magnetic Flux Leakage
(1) A mathematical model of weldpool surface deformation and keyhole formation in PAW+TIG DSAW process is developed on the basis of magnetohydrodynamic theory and calculus of variations with considering all kinds of dynamic factors acting on the weldpool. (2) Welding current of PAW+TIG DSAW process flows in from the TIG bottom side of workpiece, along the keyhole and metal neighborhood and away...
متن کاملTheory and Application of Magnetic Flux Leakage Pipeline Detection
Magnetic flux leakage (MFL) detection is one of the most popular methods of pipeline inspection. It is a nondestructive testing technique which uses magnetic sensitive sensors to detect the magnetic leakage field of defects on both the internal and external surfaces of pipelines. This paper introduces the main principles, measurement and processing of MFL data. As the key point of a quantitativ...
متن کاملDetection of Mechanical Damage Using the Magnetic Flux Leakage Technique
Since magnetism is strongly stress dependent, Magnetic Flux Leakage (MFL) inspection tools have the potential to locate and characterize mechanical damage in pipelines. However, MFL application to mechanical damage detection faces hurdles which make signal interpretation problematic: 1) the MFL signal is a superposition of geometrical and stress effects, 2) the stress distribution around a mech...
متن کاملResidual Magnetic Field Sensing for Stress Measurement and Defect Detection
The evaluation of both applied and residual stresses in engineering structures to provide early indications of stress status and eventual failure is a fast growing area in non-destructive testing. Much work has been done in recent years in the development of magnetic stress measurement techniques for ferromagnetic materials using applied magnetic fields to monitor changes in the magnetic proper...
