Which type of intermodal tank is typically used to transport materials with high-pressure requirements?

The tube module/trailer is the type of intermodal tank specifically designed for transporting materials that require high-pressure conditions. This design typically features reinforced structures that can withstand the significant stresses associated with pressurized cargo, making it suitable for gases or liquids that must be kept at elevated pressures during transport.

In contrast, the other options typically serve different functions or are designed for different types of materials. For instance, IM 102 and IM 103 intermodal tanks are used for the transport of liquids, but they are not primarily constructed for high-pressure requirements; they focus more on moderate pressure conditions. Nonregulated tank containers are not suitable for transporting hazardous materials that require high pressure, as they do not meet the standards necessary for such applications. Thus, the tube module/trailer stands out for its specific design intended to handle high-pressure transport securely and efficiently.
