The NDE laboratory consists of three elements, the linear test rig, electromagnetic finite element modeling capability, and the experimental field measurement system. The linear test rig is the centerpiece of the NDE Laboratory. The linear test rig can be used to simulate in-line inspection conditions in a laboratory environment for the evaluation and development of new technologies. The electromagnetic finite element modeling capability is used to calculate magnetic flux leakage fields and signals from metal loss defects under static and dynamic conditions and examine magnetization methods. Finally, an experimental magnetic field mapping system provides precise sensor positioning and data recording for sensor and inspecion technology development. The finite element modeling and experimental field mapping systems can be used to develop in-line inspection technology. The linear test rig facilitates the implementation of technology from the laboratory to the pull rig, flow loop, and eventually in-line inspection tools.
