OSTI ID:377481
The objective of the project was to assess the feasibility of using the magnetic flux leakage (MFL) technique to detect mechanical damage defects in natural gas pipelines and, if viable, begin to quantify its potential. Having an in-line inspection technique to detect and characterize mechanical damage defects, especially those defects which may lead to delayed failure, is important. Mechanical damage components were classified as removed metal, simple gouges, and simple dents. For each of these primary components, the defect will generally consist of geometric deformation and cold working of the pipe material. Both must be known to determine defect severity.
