What internal working pressure range do pressure tank cars operate within?

Pressure tank cars are specifically designed to transport hazardous materials in a pressurized environment, which allows for the safe transport of gases and certain liquids that need to be kept under pressure to remain in a liquid state. The internal working pressure for these types of tank cars typically ranges from 100 to 600 psi. This pressure range is established to ensure that the materials being transported are contained properly and to mitigate the risks of leaks or ruptures, which can occur if the pressure exceeds safe limits.

In contrast, other pressure ranges, such as 0 to 25 psi or 25 to 50 psi, are too low for most hazardous materials that require pressure tank cars. Similarly, while 50 to 100 psi is feasible for some applications, it does not encompass the full capability of pressure tank cars, which are engineered to handle much higher pressures. Therefore, the range of 100 to 600 psi accurately reflects the operational standards required to maintain safety and functionality in the transportation of hazardous materials.
