Tank containers are modular, portable vessels designed for the transportation of liquid and gaseous cargoes. They feature a cylindrical tank structure, often made from materials like stainless steel, aluminum, or specialized polymers, depending on the cargo's requirements. These containers are standardized in size and configuration, conforming to international shipping norms, which allows for seamless transfer between different transportation modes, such as trucks, trains, and ships. Tank containers are equipped with valves, fittings, and safety devices to ensure secure loading, unloading, and transit of goods. They are widely used in industries such as petrochemicals, food and beverage, and chemicals, providing a reliable and efficient solution for transporting diverse products across global supply chains.
