What is a ruptured disc?

Basically the rupture disc is a device used to prevent the vessel from breaking due to increased pressure. It consists of a thin metal diaphragm that explodes when the vessel's pressure rises. Rupture discs are usually designed to reduce to 1.5 times the vessel's maximum allowable working pressure. A disc assembly consists of a thin, circular membrane usually made of metal, plastic, or graphite that is firmly clamped into a disc holder. It works on the pressure relief principle. Rupture discs are actuated by inlet static pressure and are designed to function by bursting a pressure-loaded disc. The disc may be made of metal or carbon graphite and placed in a suitable holder..
