Abstract
In order to overcome the unpiggable gas pipeline inspection problem which has been arisen as the most important issues to be solved in the gas industry, KOGAS has developed since 2011 a self-propelled In-pipe robot, which is capable of inspecting unpiggable pipelines with NDT (Non-Destructive Testing) devices such as MFL (Magnetic Flux Leakage) system or RFECT (Remote Field Eddy Current Testing) system.
This paper proposes the strategy of the development of the In-pipe robot able to be operated in the high pressure of natural gas and work together with various NDT systems according to the inspection purpose and the condition of pipelines. The safety and performance of the developed In-pipe robot was verified through the deployment into the unpiggable gas pipeline in governor station of KOGAS.
