腐食検知システム
Document Type and Number:
Japanese Patent JP7287879
Kind Code:
B2
Abstract:
To propose a corrosion detection system capable of predicting an area where corrosion occurs on the outer surface of piping/equipment and a corrosion failure risk.SOLUTION: A corrosion detection system 100 is provided with a processing device 10 and a display device 32. The processing device 10 includes: a water movement behavior calculation unit 11 that determines a position of water intrusion into a coating material from the outside and a water movement direction/region inside the coating material based on coating material information obtained from the outside or held in a storage device 20 of its own system, exterior plate information, and piping/device geometry information related to an inclination of the piping/device, and a structure and an arrangement of piping/device, determines a water movement path in the coating material based on a result of the determination, determines whether an inspection target portion is a water retention portion based on an assumption of a corrosion occurrence area when the inspection target portion is in the water movement path, and determines a corrosion failure risk of the inspection target portion based on a result of the determination as to whether the inspection target portion includes the corrosion area and the water retention portion; and a display processing unit 12 that outputs inspection contents to the display device based on a result of the determination of the corrosion failure risk.SELECTED DRAWING: Figure 1
