Heavy oil tanks / API standard 650 liquid storage tanks mainly include crude oil tanks, waste oil tanks, various special lubricating oils tanks, special fuel tanks, etc. The corrosion of API standard 650 liquid storage tanks is mainly due to the corrosion of iron and steel caused by inorganic salts, acids and sulfides in heavy oil.
The bottom part of such large oil storage tank is seriously corroded. Because the tank bottom water contains anaerobic bacteria (sulfate reducing bacteria), organic matter, sulfate and oxygen, and the solubility in these oil products is very low, and the tank bottom water is in an anoxic state, which is just a suitable environment for sulfate reducing bacteria to survive. Therefore, the internal corrosion of the tank bottom of API standard 650 liquid storage tanks is mainly pitting corrosion caused by acid corrosion and sulfate reducing bacteria. The second is the corrosion of water and oil interface, the corrosion of oil and gas interface is also more serious, and the gas phase corrosion at the top is less.
