Oil tanks are widely used in the industrial sector. As they are utilized, it is also crucial to pay attention to tank cleaning. Inadequate cleaning can lead to pipe blockages, scaling, corrosion, and low-quality oil, such as leaks and contamination due to corrosion in oil tanks. Petroleum storage tanks are typically used for extended periods. After some time, impurities will settle at the bottom and sides of the tank, reducing the tank's usable capacity and affecting its efficiency. Long-term use of oil tanks can cause corrosion and leaks. Neglecting tank inspections can pose severe safety hazards, threatening the surrounding environment and the safety of the tank area.
