A company has a gasoline tank with a capacity of 3,000 m3; its inner walls are coated with titanium nanocoating to prevent corrosion. It has been in use for over 10 years, and the anti-corrosion coating has shown no signs of failure. Since the tank area is to be integrated for storing aviation kerosene, we know that the anti-corrosion coating used on tanks for storing aviation kerosene must come with an inspection report issued by the relevant authorities; in other words, such coating must not contaminate the oil and be suitable for use on tanks designed to store aviation kerosene. This tank is an old one and does not have such a test report; therefore, the existing anti-corrosion coating has to be removed. Mechanical sandblasting was used to achieve a Sa2.5 grade for removal, but unexpectedly, the coating layer was very difficult to remove. For example, when the metal surface treatment reaches Sa2.5 level and is considered a value of 1, spraying a coating layer can result in a value of 2–3 (in terms of spraying time), and such coatings are difficult to remove. The main feature is that when a corrosion-resistant coating is applied, the coating possesses a hardness similar to that of metal, as well as a certain degree of toughness. Quartz sand sprayed onto the coating surface has a certain elasticity. Therefore, this type of coating can provide long-term corrosion protection for the inner walls of oil storage tanks. In particular, gasoline tanks and naphtha tanks, which suffer severe corrosion in oil storage tanks, exhibit advantages at temperatures below 100°C over other anti-corrosion materials used in such tanks, allowing for a longer service life.
