Reduce hidden dangers of double-layer oil storage tanks

1.the importance of cleaning double-layer oil storage tanks
The cleanliness of the double-layer oil storage tank will directly affect the oil quality. Untreated oil tanks will have pipeline blockage, scaling, and corrosion, resulting in low-quality oil. The service life of petroleum storage tanks is generally long. After a period of use, impurities in crude oil will be deposited on the bottom of the tank and the wall of the tank, resulting in a decrease in the effective capacity of the storage tank and affecting the efficiency of the storage tank. The long-term use of oil storage tanks will cause corrosion and leakage. If inspection of oil storage tanks is ignored, it will bring us serious safety risks and threaten the surrounding environment and the safety of oil storage tank areas.

2. the safe placement of double-layer oil storage tanks
Double-layer oil storage tanks are more stringent in terms of choosing where to place them. Many explosion accidents in oil storage tanks are caused by placing a lot of flammable and explosive materials around the pressure vessel, which increases the danger of oil storage tanks. There are many aspects to consider when selecting the location of oil storage tanks. First, the storage site must undergo quantitative risk analysis and cannot affect surrounding enterprises, factories, mines, and residential areas. The safety distance and risk must ensure that the impact on the surrounding area is within the standard allowable range and reasonable. The placement of oil storage tanks is the key to the safe and efficient use of equipment. 3. Lightning protection measures for double-layer oil storage tanks
In rainy weather, it is not suitable to send and receive oil. It is necessary to carry out operations in strict accordance with safety operating procedures to avoid a large number of flammable and explosive mixtures formed inside and outside the double-layer oil storage tank and lightning strikes. The lightning protection facilities of pressure vessels shall be inspected regularly to ensure their integrity and effectiveness. When installing lightning protection facilities, all metal components, electrical equipment, pipelines, etc. around the oil storage tank should be uniformly and comprehensively considered, while avoiding discharge sparks and introducing lightning waves.
