ASME containers installed in enclosed spaces of vehicles must have a maximum allowed working pressure of at least?

• A. 200 psig
• B. 250 psig
• C. 312 psig
• D. 350 psig

Answer: (C)

The correct answer is based on the standards set for ASME (American Society of Mechanical Engineers) containers used for liquefied petroleum gases (LP-Gas) in enclosed vehicle spaces. ASME containers are designed to operate safely under high pressure, and the pressure rating is a critical factor in ensuring the container can withstand the operational demands without risk of failure. In this context, the requirement for a maximum allowed working pressure of at least 312 psig ensures that the container is robust enough to handle typical LP-Gas applications while incorporating a factor of safety. This pressure rating accounts for various conditions, such as temperature fluctuations and the physical stresses that can occur when the vehicle is in operation. Choosing a pressure rating lower than 312 psig could potentially compromise safety and performance, making it less suitable for use in enclosed vehicle spaces where reliability is paramount.
