Tank systems are structures designed to store liquids or gases. They can be found in various industries, including petroleum, water treatment, and chemical manufacturing. These systems often consist of a tank, piping, and valves, allowing for the safe containment and transfer of materials. Tank systems can vary in size and shape, depending on their purpose. For example, above-ground tanks are commonly used for storing fuel, while underground tanks are often utilized for water storage. Proper maintenance and monitoring are essential to ensure the integrity and safety of these systems, preventing leaks and environmental contamination.
