| Abstract: | Aimed at the corrosion feature of the air cooler fin tube for high pressure hydrogenation refining,the defects of the air cooler fin tube in service could be accurately detected by the remote field vortex detecting technique combined with the normal vortex one.The detecting method of the air cooler fin tube in service and our detecting results were compared with those from dissection were described.The results showed that the said detecting method is of comparatively higher accuracy and reliability. |
