This paper will summarize the evolution of the EMAT technology since GE’s initial product launch in 2002. A key focus of this paper will be outlining several tool and analysis enhancements that result from the evaluation of over a 1000kms of EMAT tool pipeline inspection and 207 field confirmations. These tool and analysis enhancements are now incorporated in GE’s new 30 inch third generation EMAT I n-L ine I nspection (ILI) tool.
