A rupture disc, also known as a bursting disc, is a pressure relief device used to protect equipment and personnel from the consequences of overpressure or vacuum conditions. It is designed to burst or rupture at a specific pressure, allowing the pressurized fluid or gas to escape from the system and relieving the pressure.
Rupture discs are typically made of metal, plastic or graphite, and can be installed in a variety of applications, including pipelines, pressure vessels, tanks, and other pressure-containing equipment. They can be designed to operate in a variety of environments, such as high or low temperatures, corrosive or abrasive fluids, and hazardous or explosive atmospheres.
One of the advantages of using rupture discs over other pressure relief devices such as relief valves is that they have no moving parts and do not require any external power source. This makes them reliable and easy to maintain. Rupture discs are also used in combination with relief valves for added safety and redundancy.
Rupture discs are used in a variety of applications where pressure relief is necessary to protect equipment and personnel from overpressure or vacuum conditions. Some of the common uses of rupture discs include:
Overall, rupture discs are a critical component in pressure relief systems used to ensure the safe and reliable operation of various industrial processes and equipment.

A rupture disc is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from over pressurization or potentially damaging vacuum conditions.
Rupture discs are commonly used in railroad, nuclear, chemical, pharmaceutical, food processing, petrochemical, medical, petrochemical, aerospace, aviation, defense, and oil field applications.
Rupture discs are widely accepted throughout industry and specified in most global pressure equipment design codes (American Society of Mechanical Engineers (ASME), Pressure Equipment Directive (PED), etc.). Rupture discs can be used to specifically protect installations against unacceptably high pressures or can be designed to act as one-time valves or triggering devices to initiate with high reliability and speed a sequence of actions required.
A rupture disc usually is designed to relieve at 1.5 times the maximum allowable working pressure of the vessel. In determining the size of a disc, three important effects must be evaluated: low rupture pressure, elevated temperatures, and corrosion. Manufacturers can supply discs that are guaranteed to burst at ±5% of their rated pressures. The corrosive effects of a system determine the type of material used in a disc. Even a slight amount of corrosion can drastically shorten disc life. Discs are available with plastic linings, or they can be made from pure carbon materials.
A stand-alone rupture disk can be used in preference to a pressure relief valve in the following circumstances:
