FOOD-GRADE TANK CONTAINERS
Different ISO Tank Containers
UN portable ISO tank containers have uniform external appearance, and the construction materials, linings, and fittings vary. Tank containers are classified according to the products carried and are commonly grouped in categories and referred to among other types as CHEMICAL, FOOD GRADE, BITUMEN, GAS, and LPG tanks.
The tank container is a pressure vessel mounted in a frame. Frame dimensions comply with the International Standard Organization (ISO) guidelines and are constructed following uniform international regulations for the carriage of bulk cargoes by truck, train, or ship.
Standard exterior frame dimensions on all ISO tank containers are 20’ long by 8’ wide by 8’6’ high (609 cm x 259 cm x 243 cm). Corner castings are in each of the 8 corners, similar to standard cargo containers.
Tank containers range in size from the older size of 15,000 (3,962 US gallons) to the current sizes from 21,000 liters (5,548 US gallons) to 26,000 liters (6,868 US gallons). They are available as either insulated or non-insulated with or without steam-heat capability. There are many variations on these themes, such as the Swab Tank container mainly utilized in domestic European trade lanes in sizes up to 36,000 liters and special tanks for carriage of Bitumen and various gasses.
