Intermodal Tanks
Intermodal tanks are so called because of their ability to be transferred as
a regular container, between trucking, railroad, and marine vessels without
affecting its
contents.
Flexitank, Inc. operates
two types of 20' intermodal tanks:
1-
Rigid (ISO)
Due to their ability to safely handle a huge spectrum of products, from extremely
hazardous liquids to compressed liquified gases, the 20' ISO tank is the undisputed
workhorse in the intermodal tank industry.
There are several types of ISO tanks:
Strictly dedicated IMO 1 or IMO 2 tanks for compatible edible products are used
as food grade tanks. In addition, Flexitank
has designed special ISO tanks for specific services. Specially designed tanks
for aviation gasoline and Toluene Diisocyanate are two such examples. Most tanks
are also equipped with heating capabilities. ISO
tank barrels are typically constructed from stainless steel, except for the IMO
5's, which are all steel.
2-
Flexible
This equipment consists of a pillow type tank inside a 20' dry container, typically
in the 21,000/25,000 liter range, which could be constructed from a nylon/polyurethane
composite material (thermoplastic) or from rubber (elastomer). There are disposable
versions of the thermoplastic tank but generally they are extensively re-used.
Although they can
be washed, dedicated service is highly recommended.
Flexible tanks cannot be used to
transport hazardous materials.
Shippers are usually skeptical about using flexible tanks for permissible
products, especially if they are potentially deleterious to the environment.
Flexitank recommends flexible tanks for products sensitive to air exposure,
such as latex, and for long routes where the lower capital costs result in
substantial savings.
