Abstract

Natural gas is one of the cheapest forms of energy and is the source of more than 30% of the energy produced in the USA [1]. 280,000 miles of gas transmission lines, 90,000 miles of gathering lines and 835,000 miles of distribution lines form a vast network across the country. It is imperative to assure the integrity of this vast network, for safe and economical transport of gas.
