Abstract
The increasingly popular Remote Field Electromagnetic Technique(RFET) is being utilized for larger diameter piping. This is particularly useful for the inspection of Underground Gas Distribution Lines. The Proof-of-Principle of the method including the sensitivity and limits of detection for both pitting and wall thinning is presented in this paper.
