What is the minimum design pressure required for ASME containers installed in enclosed spaces on vehicles?

The minimum design pressure required for ASME containers installed in enclosed spaces on vehicles is set at 312 psig. This specification is crucial because it ensures that the containers can safely operate under the pressures encountered in vehicular applications. The design pressure must accommodate potential pressure increases due to factors such as temperature fluctuations and the additional forces that can act on containers in transit.

The requirement for 312 psig is derived from safety standards and regulations that aim to minimize the risk of failure or leaks, which could lead to hazardous situations, especially in enclosed spaces where propane gas is stored. By ensuring that the containers are built to withstand pressures significantly higher than typical operating conditions, safety is enhanced not only for the vehicle occupants but also for others in the proximity.

Understanding this pressure ensures proper design and installation practices in line with established standards that govern the use of propane in various applications, particularly in mobile setups where environmental and operational stresses can increase the likelihood of failure.
