Final answer:
A rupture disc is a safety device that bursts to prevent dangerous levels of pressure in a system, which is true. It's a single-use component used in industrial pressure relief systems.
Step-by-step explanation:
A rupture disc is indeed a thin metal disc that is designed to burst as a safety mechanism before the pressure in a system reaches dangerous levels. This is true, and such devices are commonly used in various industrial applications as part of pressure relief systems to protect equipment from pressure-induced damage or explosions.
The rupturing of the disc occurs when the pressure on one side exceeds a predetermined level, at which point the disc fails and releases the pressure, preventing the potential hazards associated with overpressurization. Rupture discs are designed for one-time use, and once they have burst, they must be replaced to ensure the system remains safeguarded against future pressure build-ups.
