Inspection of Unpiggable Natural Gas Pipelines Using In-Pipe Robot

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.
