Effect of Lift-off on Pipeline Magnetic Flux Leakage Inspection
On pipeline magnetic flux leakage (MFL) inspection, welds and debris are present in all pipelines and cause lift-off of the sensors and/or the magnetizer of the magnetic flux leakage inspection tool, and have the potential to affect the acquired magnetic flux leakage data. By adopting ANSYS software to simulate the effect of lift-off on the MFL signal. The results of this research indicate that...
متن کاملIntelligent 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 کاملAdaptive noise cancellation schemes for magnetic flux leakage signals obtained from gas pipeline inspection
Nondestructive evaluation of the gas pipeline system is most commonly performed using magnetic flux leakage (MF L) techniques. A major segment of this network employs seamless pipes. The data obtained from MFL inspection of seamless pipes is contaminated by various sources of noise; including seamless pipe noise due to material properties of the pipe, lift -off varia tion of MFL sensor due to m...
متن کاملAdapted GMR Array used in Magnetic Flux Leakage Inspection
GMR sensors are increasingly used for magnetic surface inspection due to their high sensitivity and high spatial resolution. In case of simple planar or cylindrical shaped components, the GMR-based inspection procedure can be automated easily. In order to reduce the inspection time we present a GMR-based NDT-system consisting of a yoke and a coil as a local magnetization unit. This way the glob...
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...
