A tank container

A tank container or tanktainer is an intermodal container for the transport of liquids,
gases and powders as bulk cargo.

A tank container is built to the ISO Standard, making it suitable for different modes of
transportation. Both hazardous and non-hazardous products can be transported in tank
containers.

A tank container is a vessel of stainless steel surrounded by an insulation and
protective layer of usually Polyurethane and aluminum. The vessel is in the middle of a
steel frame. The frame is made according to ISO standards and is 19.8556 feet (6.05
meters) long, 7.874 feet (2.40 meters) wide and 7.874 feet (2.40 meters) or 8.374 feet
(2.55 meters) high. The contents of the tank ranges from 27,000 to 40,000 liters (5,900
to 8,800 imp gal; 7,100 to 10,600 U.S. gal). There are both smaller and larger tank
containers, which usually have a size different from the ISO standard sizes. The trade
organization @TCO estimates that at the end of 2012 the global fleet of tank containers
is between 340,000 and 380,000.[1] Most of these tank containers are owned by operators
and leasing companies.
