The pressure intermodal tank is specifically designed to hold high-pressure gases at 20,684 KPa (3000 psi) or higher. These tanks are built to withstand the considerable forces exerted by gases under high pressure, making them suitable for transporting compressed gases such as propane, butane, and other industrial gases.

The design and construction of pressure intermodal tanks include robust materials and structures that can handle the intense internal pressure, ensuring safety during transportation and storage. They often incorporate pressure relief mechanisms to mitigate any risk of rupture or explosion.

In contrast, a standard intermodal tank is intended for non-pressurized bulk liquids, while a flexible tank is usually utilized for storing liquids and does not meet the stringent requirements for high-pressure gas containment. A refrigerated intermodal tank is designed for maintaining specific temperature conditions for materials that require refrigeration rather than pressure containment. Thus, the pressure intermodal tank is the appropriate choice for high-pressure gas storage and transport.
