Under the sponsorship of the Gas Research Institute (GRI), of Chicago, Illinois; INVOCON, Inc. (IVC) and Maurer Engineering, Inc. (MEI) are developing a unique, cost-efficient pipe inspection method employing ultrasonic technology. This article examines the gas industry's need for improved methods of inspection and the role that this new method can play in the satisfaction of that need. Subsequently, the article describes the system being developed. The narrative is supported by drawings of the engineering prototype. The system focuses on inspection of the three most common materials used in natural gas distribution systems: cast iron, steel, and plastic.
