What is an ISO Tank?
|
An ISO Tank is a tank container which is built to the ISO standard (International Organisation for Standardisation). ISO tanks are designed to carry liquids in bulk, both hazardous and non-hazardous. The tank is made of stainless steel and is surrounded by various types of protective layers. Different skins can be used with an ISO tank depending on the type of bulk cargo it is carrying.
It has a manhole on the top along with at least one valve and another valve on the bottom. They are shaped like a cylinder. Tanks are classified according to the specification of the tank shell and fittings. It is the classification which determines what type of product maybe carried. Although tank containers have a fairly uniform external appearance, the construction materials, linings, and fittings vary.

Advantages of an ISO Tank
|
| ISO tanks are designed to meet specific criteria according to the substance they will be carrying. They are very reliable and can withstand extreme pressure and damage. They are highly unlikely to leak, do not require additional packaging materials for the cargo, can maintain a specific temperature for temperature sensitive cargo and they can be transported by road, rail or boat.

The ISO Tank
Potential Pitfalls
|
|
|
lack of tank handling expertise can
lead to damages, loss of product,
contamination & accidents
|
|
|
|
|
|
|
shipper-owned iso tank containers with
hazardous chemicals first to be shut out
(in full ship scenario)
|
|
|
|
|
loading tank container over 95%
can lead to leakage
|
|
|
|
|
|
|
