How many pressure relief devices must ASME containers be equipped with at a minimum?

ASME containers, which are designed to store pressurized gases or liquids such as propane, are required to have a minimum of one pressure relief device. This requirement is crucial for safety, as pressure relief devices (PRDs) help to prevent overpressure situations that can lead to catastrophic failures or explosions. The PRD is essential for maintaining safe operational pressures within the container, allowing any excess pressure to escape safely and thus protecting the integrity of the container and the safety of individuals nearby.

Having at least one pressure relief device ensures that there is a mechanism in place to relieve pressure efficiently in case of an increase due to thermal expansion or other factors. This safety feature is a critical component of any ASME container design, reflecting the importance of adhering to safety standards to mitigate risks associated with handling and storing propane and other pressurized substances.
