What pressure is a rupture disc designed to burst at?

• A. 3200 psi
• B. 2600 psi
• C. 400 psi
• D. 5000 psi

Answer: (A)

A rupture disc is a safety device that stays sealed during normal operation and is designed to open at a specific bursting pressure to relieve excess system pressure before equipment is overstressed. That chosen pressure must be high enough to avoid nuisance ruptures but low enough to protect the vessel. In this scenario, 3200 psi hits a sensible balance: it’s high enough to avoid opening during regular operation, yet low enough to relieve pressure before the equipment’s limits are exceeded. The other numbers would either vent too early (400 psi) or be too close to or exceed typical operating conditions (2600 psi or 5000 psi), making them less appropriate for reliable protection.
