Electro Magnetic Acoustic Transducer Sensor for Small Diameter and Unpiggable Pipes; Prototype and Testing DTPH5615T00018L


The project developed and then demonstrated the ability of the Electro Magnetic Acoustic Transducer (EMAT) crack tool to detect tight/closed cracks down to 2MM deep for 8” diameter pipes in traditionally difficult to inspect pipelines. The Intellectual Property from this research and from the prior research project under PHMSA contract # DTPH56-13-T-000007 evolved into a free-swimming tool that operates at 2 m/s, navigates 1.5 diameter bends, and can be pressurized to 2,200 psi. The EMAT Crack In Line Inspection tool is now being offered by Baker Hughes/Qi2 Elements.
