Rupture disks have been the go-to system for protecting vessels from over-pressurization. Miniaturization of these rupture disks has brought new setbacks in materials and designs.
Burst disks are widely chosen over safety valves due to their quick response and evacuation of the vessel. These disks are produced to “fail” at a predetermined pressure difference between both faces of the disk. It is when they fail at that pressure that they protect the vessel from failing in a more disastrous manner.
As rupture disks are made smaller and smaller, low rated disks must use paper-thin metals easily broken during handling, assembly, and operation. It is recommended to use these disks when operation pressures are 75% or less of the rated burst pressure.
