ISO tank containers are the backbone of bulk chemical logistics, ensuring the efficient transport of hazardous chemicals, gases, or liquids. Understanding the lifecycle stages of these containers is crucial for appreciating their sustainability and vital role in global logistics.
An ISO tank container is a container designed for transporting liquids or gases. These versatile containers can be used on ships, roads, railways, and in air logistics, making them integral to combined transport operations. Standardised in size and composition according to the ISO 668 standard set by the International Maritime Organisation, these containers are often referred to as ISO tanks or intermodal tanks.
The development of ISO tank containers has been significantly shaped by the requirements of the chemical and food industries. These containers can be customised to meet specific transport needs, making them versatile tools for transporting various types of cargo, including gases, liquids, foodstuffs, and dangerous goods.
Producing ISO tank containers requires extensive experience and specialised knowledge. Strict safety regulations and cargo-specific requirements influence the choice of materials, insulation thickness, baffles, and the design of valves and connections. The manufacturing process includes rigorous quality controls and a series of tests, such as leakage and hydrostatic pressure tests. Once a tank container passes these tests, it receives the necessary certifications for commercial use.
The choice of an ISO tank container depends on the characteristics of the transported goods, such as weight, density, and reactions with other substances. The dimensions of these containers align with those of standard ISO containers, facilitating their use in combined transport systems. Additional measures, such as specific documentation, cleaning methods, and handling procedures, may be required based on the cargo.
Post-transport, ISO tank containers undergo thorough cleaning and comprehensive inspections to detect and address any damage. For dangerous goods, mandatory air pressure tests every two and a half years and water pressure and water tightness tests every five years ensure functional safety. With proper maintenance, a tank container can last between 20 to 30 years. Refurbishment or overhauling may extend their lifespan further, involving the replacement or renewal of various components.
When a tank container is no longer safe or economically viable, it can be recycled. This involves thorough cleaning to remove hazardous residues, followed by recycling processes handled by specialists. Made predominantly of high-quality stainless steel, these containers are 90 percent recyclable through established metal recovery processes.
ISO tank containers are essential to the logistics industry, offering a sustainable solution for the transport of bulk chemicals and other goods. Their lifecycle, from production to recycling, reflects the industry’s commitment to efficiency, safety, and environmental responsibility.
