Tank trucks are specialized vehicles designed for the transportation of liquids and gases. They consist of a chassis and an attached tank, which can vary in size and capacity depending on the intended use. The tanks are constructed from materials such as steel, stainless steel, aluminum, or composite materials, selected based on the nature of the cargo, such as its corrosiveness, flammability, or toxicity. Tank trucks are equipped with pumping systems, valves, and hoses for loading, transporting, and dispensing the cargo. Safety features, including double - walled tanks, emergency shut - off valves, and leak - detection systems, are standard to prevent spills and ensure the safe transit of hazardous or non - hazardous liquids and gases. These trucks are widely used in industries such as oil and gas, chemicals, food and beverage, and water treatment for the efficient movement of bulk fluids.
