Pipelines play an important role in the national/international transportation of natural gas,
petroleum products, and other energy resources. Pipelines are set up in different …

Oil and gas pipelines are very important for fuel transportation, however leakages in them
may lead to life and property losses due to the release of the energy they contain. Reliable …

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 …

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

Shearography and thermography are optical techniques, both proven to be valuable tools
for material nondestructive evaluation. Papers on these topics, however, are scattered and …

Today's main energy sources; natural gas, petrol and petroleum products are transported via
pipelines that are safe at long distances. Most of these pipelines are buried and their …

Today, natural gas and oil, called main energy sources, are transported by pipelines at long
distances. Defects (corrosion, cracks, dents) in the buried pipelines can cause loss of life …

Nowadays, there is a strong demand for inspection systems integrating both high sensitivity
under various testing conditions and advanced processing allowing automatic identification …

This paper investigates two non-destructive evaluation methods, magnetic flux leakage
(MFL) and eddy current pulsed thermography (ECPT), for both artificial and natural multiple …

The investigation described in this paper focuses on the velocity effect of dynamic
magnetization and magnetic hysteresis due to rapid relative motion between magnetizer …
