What is the pressure range associated with low-pressure tank cars?

The pressure range associated with low-pressure tank cars is defined as being below 25 PSI. Low-pressure tank cars are designed for the transportation of liquids that do not require high pressures for safe containment. Typically, these are used to transport materials that can include chemicals, fuel oils, and other substances that are stable at low-pressure conditions.

The correct choice falls below the thresholds associated with higher-pressure tank cars, which operate at pressures above 25 PSI. Therefore, while low-pressure tanks may not exceed 25 PSI, high-pressure systems would fall within ranges starting from 25 PSI and extending upwards, highlighting the significance of understanding these specifications for proper handling and safety during transport of hazardous materials.
