What affects the service life of double-layer oil storage tanks? In recent years, with the continuous growth of human demand for energy, many ports and refineries in China have established a large number of oil storage tanks. The reliable operation of these facilities is directly related to production and environmental safety. The length of its service life also directly affects the economic benefits of refineries. The design life of the fuel tank is generally 20 years. However, oil stored in oil tanks typically contains corrosive chemicals such as hydrogen, sulfuric acid, organic and inorganic salts, as well as water. In addition, the outer wall of the fuel tank is affected by environmental factors, and the service life of the fuel tank can be shortened to about 5 years. Some cases of severe corrosion may lead to tank corrosion and perforation within about a year. If corrosion perforation occurs during non maintenance periods, the resulting losses will be greater. If metal oil tanks cannot be treated in a timely manner, they may cause surface corrosion and pollution to the oil, leading to an increase in viscosity, acidity, and salinity of the oil, and affecting the quality of the oil; Corrosion can lead to oil tank perforation and oil leakage, not only causing energy waste and environmental pollution, but also easily causing fires and explosions, and its danger can be imagined. The fatigue loss caused by corrosion directly affects the strength of oil tanks and is the main reason for reducing their service life.

Therefore, it is crucial to do a good job in anti-corrosion of double-layer oil storage tanks. If you want to learn more about oil storage tanks, please continue to follow Lu Qiang!
