What type of intermodal tank is designed for working pressures of 100 to 500 psig and used for transporting liquefied gases?

• A. IMO Type 5
• B. IMO Type 1
• C. IMO Type 2
• D. IMO Type 3

Answer: (A)

The correct answer is based on the specific design features and intended use of the different tank types. An intermodal tank classified as IMO Type 5 is specifically designed to handle the transportation of liquefied gases under higher pressures ranging from 100 to 500 psig. This type of tank is optimized for these pressures, making it suitable for transporting substances such as propane and butane, which are typically found in a liquefied state under pressure.

IMO Type 5 tanks are constructed to ensure safety and integrity while carrying these types of hazardous materials. The ability to withstand high pressures is a critical characteristic that distinguishes it from the other tank types, as they have varying pressure ratings and design functionalities. For instance, types 1, 2, and 3 handle a range of bulk liquids and gases but are not specifically tailored for the same high-pressure conditions as Type 5. Therefore, its unique capabilities for liquefied gases at elevated pressures make Type 5 the appropriate choice for this application.
