What are they?

Bursting discs, also known as rupture disks, pressure safety discs or burst diaphragms is a critical safety component found worldwide in processes involving pressure and/or vacuum. A disc, typically paired with a holder is designed to burst/rupture at a predetermined pressure or vacuum.
Bursting discs are fundamentally engineered weak points; designed to fail before a process can reach its maximum design limits and are therefore vital in both preventing accidents and serious damage to process components A bursting disc relieves overpressure and are essential components across a broad range of applications from sanitary; ventilators, car airbags, emergency relief valve isolation, and much, much more.
