What Is a Rupture Disc?
A rupture disc is a pressure safety device used in chemical and nuclear plants to manage pressure levels. It activates when the pressure within a system exceeds a predetermined safe limit.
Constructed from thin metal, the rupture disc is designed to burst open once the pressure of the contained fluid or gas surpasses the set threshold. This action rapidly releases excess pressure, bringing it back to a safe range. Such a mechanism is vital for protecting the equipment from damage and ensuring the safety of both the environment and the operators.
While similar in function to a safety valve, a rupture disc offers a more effective solution for preventing leaks of flammable, toxic, or expensive gases, as well as radioactive liquids. Its quick response in releasing pressure makes it a preferred choice in critical safety applications.
