Abstract	The report is one of a series of four topical reports published by the Gas Research Institute (GRI) on the methods being used by pipeline operators to assure the integrity and safe operation of the domestic natural gas transmission system. The pipeline system in the United States has been constructed over the past half century. Assuring the integrity of the system will provide long-term serviceability to meet the future demands for natural gas. The topical report summarizes the current state of the most commonly used in-line inspection method, magnetic flux leakage (MFL). Not everything about MFL technology is known. Rather, the report presents current information on MFL techniques for pipeline inspection as they are understood by the authors. MFL is an in-line inspection method used to inspect gas-transmission pipelines. MFL inspection tools are completely self-contained units that move through pipelines at 2 to 6 miles per hour. All MFL tools have systems for magnetizing, sensing, data recording, and power. MFL tool performance is affected by many design and operational parameters. On-going research efforts are aimed at more fully understanding these parameters. MFL can generally detect metal-loss corrosion in pipelines. However, MFL cannot reliably detect all types of anomalies.
