Tank cleaning, oil storage tank cleaning, diesel tank cleaning, heavy oil tank cleaning, and the significance and necessity of petroleum storage tank cleaning: The cleanliness of oil storage tanks affects the quality of the oil, and the health condition of the tanks threatens the surrounding environment and the safety of the tank area. Maintaining tank cleanliness and scientifically controlling tank wall corrosion is crucial for oil companies.

Maintain the cleanliness of the internal tank to minimize contamination of the oil products.
     Various metals and rust can induce the oxidation and deterioration of oil products. Applying an anti-rust coating to the inner wall of oil tanks can effectively prevent the catalytic effect of metals on the oxidation of oil products. The sediment at the bottom of gasoline and diesel storage tanks is mainly rust. During the oil unloading process from the tank, the sediment at the bottom is stirred up, and the powdered rust can dissolve into the oil. If vehicles are fueled with such oil products, it can cause significant harm to the vehicles themselves. After five years of accumulation of sediment at the bottom of a diesel storage tank, the thick sludge at the bottom will reach 15 Approximately centimeters. Regularly cleaning oil storage tanks and applying anti-corrosion coatings on the interior tank walls is an effective measure to prevent metal oxidation and rust, as well as to slow down the deterioration of oil quality.
Secondly, the contamination of oil tank products by water and impurities should not be overlooked. Water impurities in oil tank products are predominantly introduced during transportation, loading, unloading, and storage processes. Long-term storage of oil tank products can also cause the separation of water that has dissolved into the oil, leading to the formation of an acidic water layer at the bottom of the storage tank. Among all oil products that have deteriorated due to storage, a significant majority are found to be of substandard quality due to the admixture of water impurities. Various mechanical impurities mixed into the oil products not only block filters and oil passages, causing supply failures, but also increase wear on components and may lead to adverse consequences such as scratches on friction surfaces. The water mixed into the oil products can corrode machinery (water can freeze in low temperatures, blocking oil passages); the presence of water can cause some additives like detergents, antioxidants, and anti-knock agents to decompose and precipitate, rendering them ineffective; and the presence of water accelerates the oxidation rate of oil products within the tank, increasing the formation of gums. Additionally, the acidic water layer that accumulates at the bottom of the tank accelerates the corrosion of the oil storage tank, potentially thinning the tank walls and causing leaks.
