Analysis of Corrosion Causes and Research on Protective Measures for Large Crude Oil Storage Tanks
By investigating the composition of corrosive substances in the sediment water on the bottom plate of large crude oil storage tanks,soil resistivity,etc.,the causes of tank corrosion are analyzed,and corresponding joint protection measures of coating corrosion prevention and cathodic protection are proposed.A new cathodic protection method is adopted,and the anti-corrosion effect is tested.The results showed that the cathodic protection effect of the tank using the new intelligent synchronous constant breaking potential meter anti-corrosion measures was significant,effectively reducing the corrosion rate of the tank bottom plate and lowering maintenance costs.
