In recent articles in LM, we shared an in-depth look at the pros, cons and ideal uses of flexibags. This week, we continue our research by taking a closer look at another staple of liquid bulk transport: ISO tank containers. The first tank container was invented in 1964, but it wasn’t until 1966 that they began to be mass-produced and built according to ISO standards. Since then, the ISO tank has been a crucial tool for chemical transport.
Whereas flexibags make a great solution for food products and non-hazardous chemicals, ISO tank containers can handle a wider variety of cargo. Built to ISO standards and made of stainless steel, these containers can handle both hazardous and non-hazardous materials – in liquid, gas and powder form. One ISO tank can carry 20,000 – 26,000 liters of material, depending on the cargo. With a 20-foot frame, ISO tanks are perfect for intermodal transport solutions, as they’re suitable for container ships, trucks and rail.
ISO tank containers are also designed to be reused, meaning they offer environmental and cost benefits as well. Because they can be reused again and again for years, ISO tanks make a very good investment. And because they aren’t disposed of after just one or a few uses, they contribute a smaller carbon footprint.
Of course, in order to extend the working life of your ISO tank, it’s necessary to keep up with proper maintenance, including cleaning and repair. Cleaning is especially important after the tank has carried a shipment of hazardous chemicals. It’s also vital to select a responsible service provider that disposes of cleaning waste water in an environmentally friendly manner, ensuring that neighboring communities are not being polluted. When it comes to repair, it’s incredibly crucial to perform thorough inspections of each tank. If any damage, no matter how minor, is left unattended, it could potentially lead to even greater problems in the future, like leakage.
From flexibags to ISO tanks to drums, there are a lot of options for transporting liquids in bulk. Here at LM, we hope that our articles can help shed a little light on these products’ unique advantages and drawbacks.
