A rupture disc is a safety device used in various industries to protect equipment from overpressure. It consists of a thin, fragile membrane that bursts when a specific pressure is exceeded, allowing the excess pressure to escape. This helps prevent potential damage to vessels, pipes, and other systems. Rupture discs are commonly found in systems involving steam, gas, or liquids. They are often used in conjunction with other safety devices, such as pressure relief valves, to ensure a comprehensive safety approach. Proper selection and installation of rupture discs are crucial for effective pressure management.
