Introduction of In-Line Inspection Technology in KOGAS

This paper focuses on the introduction of the development of in-line inspection technology in Korea Gas Corporation to keep maintaining the integrity of pipeline facilities. There are pipeline systems in oil and gas industry with various installations such as valves, tees, miters and bends as well as many operating condition such as operational pressure, flow-rate and temperature which result in piggable and un-piggable. This paper introduces results of research and development of in-line inspection technology for verifying the integrity of piggable and un-piggable pipeline in KOREA. KOGAS has produced results with values in the development of robotic inspection technology equipped with NDE (Non-Destructive Evaluation) for un-piggable pipeline and as well as the development of conventional in-line inspection technology for piggable pipeline since 2000.
