Application of Reticular Anode Cathodic Protection System on Outside Bottom Plate of Oil Tanks

Taking two 50000 m³ oil tanks ' commissioning in Alashankou Pumping Station for example, monitoring and analysis are carried out to the cathodic protection system with reticular anodes at outside bottom plate of oil tanks. It is pointed out that utilizing the reticular anodes to protect the bottom plate can make the protective current uniformly distributed, shielding free and without interference, the protective potential at all positions being basically equal, and the reticular anodes be near-range installed. Field debugging is conducted to deal with the issues to be regarded in design and construction, and relevant improving suggestion is put forward.
