Which PSI range defines the rupture point for safety burst discs in this context?

• A. 2650-3000 psi
• B. 2500-2600 psi
• C. 2000-2100 psi
• D. 3000-3200 psi

Answer: (A)

Burst discs are safety devices that relieve pressure once the system reaches a predetermined rupture pressure. That rupture pressure must be higher than normal operating pressure but well below the vessel’s maximum safe pressure, so relief happens in time to prevent damage. In this context, a rupture range of about 2,650 to 3,000 psi provides the needed margin: it stays intact during normal operation, yet will open before the system reaches dangerous levels. The other ranges either sit too low and would vent during ordinary use, or push the relief too far up, risking overpressure before relief occurs.
