Main Objective
Developing a non-contact Magnetic Barkhausen Noise (MBN) technique for measuring stress in pipelines. MBN is the result of discrete jumps in magnetization of the material as domains align, and in Phase II, we demonstrated these jumps are strongly correlated to the stress state of a pipe. Our approach focuses on refining the sensor first for in-the-ditch measurement prior to development of an inline inspection tool. Our Phase IIB aims to address the technical and commercial challenges associated with developing, implementing, and commercializing pipeline inspection hardware.
