What is the typical design burst pressure for a rupture disc?

The typical design burst pressure for a rupture disc is commonly set at 15 PSIG (pounds per square inch gauge). Rupture discs are safety devices used to protect equipment and systems from overpressure conditions by providing a predetermined pressure relief point.

In designing these rupture discs, engineers typically select a burst pressure that is appropriate for the specific application they are intended for. The 15 PSIG benchmark often serves as a standard because it allows for safe operation of many systems while ensuring that if pressure exceeds this level, the disc will rupture and release the pressure before catastrophic failure of the system occurs.

Choosing a burst pressure that's too low might lead to unnecessary ruptures during normal operation, while a burst pressure that's too high could result in equipment damage and unsafe conditions if the overpressure situation is not mitigated in time. Therefore, the designation of 15 PSIG is a well-established option for various industrial applications, enhancing safety while managing operational pressures effectively.
