Rupture disk

From GAWDAwiki

A rupture disk or bursting disk is a device used to protect pressure vessels and systems from overpressure, which can result in equipment failure or injury to operators. It has the same purpose as a relief valve, but can reacts more quickly to high pressure. A rupture disk is destroyed when it is used, making it one-time use part.^[1]
