What is the minimum rated working pressure for container appurtenances?

The minimum rated working pressure for container appurtenances is 250 psig. This specification is crucial for ensuring safety and reliability in propane handling systems. The higher pressure rating helps ensure that the appurtenances can withstand the operational pressures encountered in propane service without failure, which is critical for maintaining system integrity and preventing hazardous situations.

In the context of propane systems, container appurtenances are integral components such as valves, pressure regulators, and fittings that are directly connected to the propane container. Given the variability in temperature and external conditions, the appurtenances must be capable of enduring pressures that can be significantly influenced by these factors.

A minimum rating of 250 psig provides a buffer that accommodates fluctuations in pressure and ensures that even in extreme situations, the appurtenances will perform safely. It reflects industry standards that prioritize safety and function, thus preventing leaks or ruptures that could lead to dangerous incidents.
