Abstract
In oil refinery and chemical industry, electric -power industry, etc., aged facilities have been a serious problem. Especially, large-sized facilities, the solution is difficult. In order to solve this problem, we need two diagnostic technologies. One is the high-speed inspection technology of securing safety in the wide area, and another is the precise diagnostic technology of grasping a damage grade and a size correctly. The engineer belonging to facility management shall be utilized such technology well. Based on such an idea, the high-speed corrosion inspection technology that we are developing recently for a tank, a pressure vessel, etc. is reported.
