To advance the capability of nondestructive internal pipeline inspection devices, commonly called inspection pigs, two test bed vehicles have been built as test platforms for use in the GRI Pipeline Simulation Facility. This report describes the magnetic flux leakage test bed vehicle. Magnetic flux leakage was selected for a specific test bed vehicle implementation because it is the most commonly used in-line inspection technology for the detection of metal loss defects in gas-transmission pipelines. The other test bed vehicle is called the advanced sensor test bed vehicle, which can be used for experiments involving ultrasonics, eddy currents, electromagnetic acoustic transducers, or hybrid techniques (multiple inspection technologies). The magnetic flux leakage test bed vehicle was designed to simulate magnetic flux leakage technology, as well as advance the state of the art of the technology.
