Rupture Discs - Failure is Definitely an Option

Rupture discs are designed to fail. That's their job. 

These sacrificial parts are designed to burst when pressure within production equipment exceeds a certain threshold by breaking down, stopping the process to prevent or mitigate hazardous events. Rupture discs are critical instruments utilized so that companies can ensure process safety as set forth by the International Safety Standards (IEC 61508/61511). These devices prove most effective when they fail according to pre-established specifications. Inferior rupture discs often cause unnecessary and expensive production shutdowns due to the lack of quality testing and expertise in manufacturing.

A rupture disc (pressure safety disc, burst disc, bursting disc) is a “one and done” pressure relief device most often used to protect a vessel, pipe, or container from over pressurization. As opposed to pressure relief valves, rupture discs are designed to function only one time by providing an instantaneous response to an over-pressure condition.

Rupture discs are commonly used in chemical, petrochemical, nuclear, aerospace, medical, railroad, pharmaceutical, food processing and gas & oil applications. They provide primary or backup protection. Very often rupture discs are used in tandem with safety relief valves, protecting them from the process media and extending the life of the relief valve.
