There’s a lot less to think about when products are shipped via a dry trailer versus bulk liquid tanks. The liquid bulk tank can come in many different types, each to serve a particular purpose. In fact, bulk liquid storage isn’t all the same. In this article, we evaluate the different types of bulk liquid storage tanks and show you what’s important about each.

ISO Tanks

The ISO Tank is one of the most standard bulk liquid tanks. It’s one of the most common used for liquid transportation. Each container is constructed from a stainless steel hull with an inner layer that contains protective material layers to prevent corrosion. With this construction, the container can easily store and transport hazardous and non-hazardous products. It is even used for transporting flammable materials.

ISO tanks get their name from the International Organization for Standardization, the company that is responsible for setting parameters on the container itself. Most ISO tanks look like a cylinder containing a hole in the top with a valve at the end of unloading. ISO tanks often carry juice, milk, alcohol, vegetable oil, gasoline, liquid petroleum gas, hazardous chemicals and more. As the most popular bulk liquid tanker carriers, the tanks can usually hold between 5,000 and 11,000 gallons.

Flexitanks

The flexitanks are collapsible bulk liquid trailers that are constructed from polyethylene layers and a reinforced wall for the outer layer that contains an interwoven polyethylene material. Due to it being collapsible, it can be used in a 20-foot container to carry non-hazardous liquids. It fits perfectly in a standard shipping container where it can be filled and emptied.

Inside the shipping container, more support is given to the flexitank without making expensive changes to the truck. Most flexitanks are constructed to hold 4,000 to 6,300 gallons of liquid transportation, so they aren’t designed for regular use on a larger scale like the ISO tanks are. However, these bulk liquid trailers make it easy to transport fluids without changing the trucking lineup.

Characteristics of Bulk Liquid Tanks

The characteristics of the tank truck’s bulk liquid transfer solutions depend on what is used.

  • Material: Most tanks are made from a stainless steel material with protective properties that prevent corrosion. However, the flexitank is constructed from polyethylene that can be collapsed.
  • Insulation: Bulk liquid tanks can be insulated or non-insulated, depending on the needs. Insulation can keep the warm liquids warm and the cold products cold.
  • Volume: The ISO tanks can hold much more than flexitanks and are used for everyday operation.
  • Loading/Unloading: It’s much easier to load and unload an ISO tank, but the flexitank isn’t difficult to use.
