What is the maximum working pressure for a cryogenic rail car?

The maximum working pressure for a cryogenic rail car is 25 psi. This pressure is crucial for safely transporting liquefied gases at very low temperatures, and it ensures that the contents remain in a liquid state and do not vaporize. Cryogenic materials require specialized equipment designed to handle the unique characteristics of these substances, including extremely low temperatures and the potential for pressure buildup during transport.

At higher pressures, there is an increased risk of leaks or ruptures, which can be dangerous due to the volatile nature of cryogenic materials. Understanding and adhering to the maximum working pressure is essential for the safety of personnel, equipment, and the environment during the handling and transportation of these materials. By adhering to the specified standards of 25 psi, operators can maintain control and mitigate hazards associated with cryogenic transport.
