With the rising demand for liquid chemicals and energy logistics worldwide, ISO tank containers are becoming increasingly popular due to their safety, standardization, and suitability for intermodal transport. Depending on their working pressure, ISO tanks are generally categorized as follows:
4 bar tanks (T11 type): Used for food-grade liquids and general chemicals such as alcohol, glycols, and juice concentrates. Suitable for low vapor pressure products.
6–8 bar tanks (T14/T20 type): Designed for more hazardous or corrosive chemicals such as nitric acid and phosphoric acid, often requiring corrosion-resistant materials.
17–24 bar tanks (T50 type): Mainly for high-pressure liquefied gases, including LPG, ammonia, and refrigerants.
22 bar and above, vacuum-insulated tanks (T75 type): Specifically designed for cryogenic liquefied gases such as LNG, liquid oxygen, nitrogen, and argon.
Industry experts note that different pressure levels correspond to different storage and transport requirements. With the global push toward clean energy, the demand for cryogenic tanks (T75 type) is expected to continue growing.
