| Abstract: | Corrosion mechanism and corrosive conditions of oil tank inner wall were narrated,combined protective countermeasure of coating and sacrificed anode and its application at 10~5 m~3 oil storage tanks bottom plates in a seaport in Dalian were introduced.The result show that protective potential of oil tank bottom plates inner wall was more lower than-0 85 V(Cu/CuSO 4)after cathodic protection.It indicated that cathodic protection system was stable after implement of sacrificed anode protection in bottom plates inner wall of oil tank.the working potential of the anode maintained the lower value.It resulted in inner wall of oil tank bottom plates being protected entirely.And it reached designed technique target. |
