A rupture disk or rupture disc is a type of sacrificial part intentionally engineered to fail under excess pressure, either positive or vacuum. The membrane is usually made out of metal, but nearly any material (or different materials in layers) can be used to suit a particular application. The pressure relief valve provides instant response (within milliseconds or microseconds in very small sizes) to an increase or decrease in system pressure, but once the disk has ruptured it will not reseal. Major advantages of the application of rupture disks compared to using pressure relief valves include leak-tightness, cost, response time, size constraints, and ease of maintenance.

In Coestan, we manufacture made to order rupture discs in different materials, according to our clients’ requirements also Fike and Lamot.
