ISO Tank containerss in the USA are typically 20 ft. long x 8 ft. 6 in high x 8 ft. wide. They come in a variety of capacities largely suited for the cargo they carry (12,000L, 14,500L, 21,000L, 24,000L etc.). The tank itself is manufactured out of stainless steel, namely 316L. The frame dimensions are ISO standards also to allow for the tank to be easily mounted on ship, train, or chassis. T11 ISO Tank containers have an 8 ft. tall ladder along the sides that allow access to the top of the container. Due to the cylindrical shape of the tank, they are outfitted with aluminum catwalks so that operators can access the different valves. Most tanks have a 20” manlid for filling with product and a bottom discharge valve to best use gravity feed. Tanks can be outfitted with cladding and insulation and steam heat systems to keep their products heated to a certain degree. Most T11 tanks are chemical tanks or hazmat tank containers for bulk liquid loads. Other specialty ISO tanks are outfitted with cooling systems and insulation to keep certain chemicals or food products such as milk in a refrigerated state, these are called Food Grade ISO Tank Containers. Please see some examples below.
