What is the name of the specialized intermodal container that transports gases in high-pressure cylinders (3000-5000 psi)?

• A. Tube module
• B. Compressed gas tube trailer
• C. IMO Type 5
• D. Cryogenic liquid tank

Answer: (A)

High-pressure gas shipments are kept in a rigid, multi-cylinder containment that is specifically built to move between trucks, trains, and ships. This intermodal container is called a tube module. It is designed to hold cylinders pressurized in the 3,000–5,000 psi range, providing a secure frame, cylinder separation, venting provisions, and compatibility with standard intermodal handling. The other options describe different types of equipment or packaging: a cryogenic liquid tank is for ultra-cold liquids, not high-pressure gases; IMO Type 5 refers to a separate packaging category not used for this intermodal container; a compressed gas tube trailer is a road trailer used for transporting tubes but not an intermodal container that can seamlessly move across modes. So the tube module is the specialized intermodal container designed for high-pressure gas cylinders.
