The storage tank is affected by internal and external environment media for a long time, and the corrosion is easily generated on a bottom plate, an exposed edge plate, a bottom ring wall plate and a top plate of the storage tank. For the interior of the oil storage tank, the corrosion of the tank top is generally far stronger than that of the tank bottom, and corrosive gas in the crude oil storage tank rises to the tank top area in the tank and is deposited after meeting an aqueous medium on the surface of an accessory, so that chemical corrosion occurs. The main corrosion factors are carbon dioxide corrosion, sulfur corrosion, and the like. The tank top may cause the steel plate to become thinner and deform due to long-time corrosion, perforation is generated, the service life of the oil tank is shortened, and serious environmental pollution problems can be caused once crude oil leaks due to corrosion perforation, and serious fire and explosion accidents can be caused.
