What is the designed operating pressure for ASME propane containers?

The designed operating pressure for ASME (American Society of Mechanical Engineers) propane containers is indeed 312.5 PSI. This pressure is a standard established to ensure safe operation within the design limits of the containers used for storing and dispensing propane. It is essential for the integrity of the container and the safety of the propane systems that this operating pressure is maintained and adhered to during usage.

ASME containers are constructed to specific guidelines, including the ability to withstand this pressure safely. This compliance is part of regulations that govern the safe design, manufacture, and testing of pressure vessels used in the industry. The designation of 312.5 PSI allows for effective operation while also offering a safety margin to accommodate fluctuations in pressure and temperature, ensuring the safety and reliability of propane storage systems.

Higher pressures, such as those indicated in some incorrect options, exceed the standard for most ASME containers and could lead to safety hazards if not properly accounted for in container and system design. Each of those pressures would result in containers needing different materials or construction methods to ensure safety and compliance. Thus, 312.5 PSI stands as the correct and widely accepted operating pressure in the industry for ASME propane containers.
