Pipelines carrying energy products play vital roles in economic wealth and public safety, but
incidents continue occurring. Condition assessment of pipelines is essential to identify …

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 …

Magnetic particle inspection (MPI) is a highly sensitive and user-friendly nondestructive
technique that remains essential for detecting surface and near-surface defects in …

In most current nondestructive testing systems, a magnetic flux leakage (MFL) method is
widely used in various industry fields, where the structural integrity of specimens is of vital …

This paper proposes an injurious or noninjurious defect identification method from magnetic
flux leakage (MFL) images based on convolutional neural network. Different from previous …

Magnetic flux leakage testing (MFL) is the most widely used nondestructive testing
technology in the safety inspection of oil and gas pipelines. The analysis of MFL test data is …

The magnetic flux leakage (MFL) defect detection of oil and gas pipelines faces two tasks,
defect type identification and defect size and shape estimation. However, there are few …

Signals collected from the magnetic scans of metal-loss defects have distinct patterns.
Experienced pipeline engineers are able to recognize those patterns in magnetic flux …

The magnetic flux leakage (MFL) internal detection is one of the most effective methods for
assessment of long-distance oil and gas pipelines. To quantify the outer surface defect …

Cracks that may cause pipeline cracking and leakage become the main risk of in-service
pipelines after conventional metal loss defects have been detected. Therefore, it is …
