A Rupture Disc, which is also known as a bursting disc, is a non-reclosing safety device used to protect piping, vessels, and equipment from excessive pressure or vacuum conditions. It has a thin slice of metal that is scored to rupture at a predetermined pressure, allowing for the immediate release of pressure to prevent injury or damage. Once a rupture disc has activated and ruptured, it is non-reusable and requires replacement.
Bursting discs are used to protect extinguishing tanks against excessive pressure as well as quick-opening systems. Propellant cartridges (CO2 pressure tanks) are also securing with bursting discs. A rupture disc needs to be replaced once it has split. Although they can be used independently, they are more often used along with a safety valve. They can be used as a backup plan if the process medium becomes too harsh. Another use is to isolate the safety valve from the process medium.

What is a Rupture Disc?
A Rupture disc is an emergency relief device made of a thin metal diaphragm that is meticulously engineered to break at a predetermined pressure. The obvious distinction between a relief or safety valve and a rupture disc is that the valve reseats, but the disc does not. Rupture discs can be fitted in parallel or in series with a relief valve. To avoid an erroneous pressure differential from forming, keep the space between the disc and the valve at atmospheric pressure. A rupture disc is typically intended to release 1.5 times the vessel’s maximum permissible working pressure. When deciding the size of a disc, three critical factors must be considered: low rupture pressure, high temperatures, and corrosion.
The discharge pipework for relief and safety valves, as well as rupture discs, should include a minimum of fittings and bends. The valve should be loaded to a minimum, and plumbing should include suitable supports and expansion joints. To avoid liquid collection in the pipework and valves, appropriate drains should be installed.
Benefits of Using Rupture Discs: Safety Devices for Overpressure Protection
- Enhanced Safety: Rupture discs provide enhanced safety by protecting persons and equipment from overpressure, preventing accidents and assuring compliance with standards.
- Cost-Effective: In operations where maintenance access is restricted, rupture discs offer simple and affordable alternative for pressure reduction.
- Cost-effective: Rupture discs are a simple and cost-effective alternative for pressure relief, especially in operations with limited maintenance access.
- Compatibility: They can be used alone or in conjunction with safety relief valves for enhanced protection, especially in demanding or corrosive settings.
Types of Rupture Discs
Rupture discs come in various types, each designed for specific applications based on the pressure, temperature, and environment they operate in. Here are some common types of rupture discs:
1. Forward-Acting Rupture Disc: A forward-acting rupture disc is convex on the pressure side, with an outward-facing curve where pressure builds up. It bursts when pressure from the concave, inner side exceeds the disc’s rated burst pressure, providing quick pressure relief. These discs are commonly used in systems experiencing static or slight pulsating pressures, ensuring safety and reliable performance.
2. Reverse-Acting Rupture Disc: A reverse-acting rupture disc is concave on the pressure side. It is designed to buckle inward when pressure exceeds a certain limit, at which point it bursts to release excess pressure. This type of disc is ideal for systems with higher pressures or rapid pressure fluctuations, offering enhanced protection in dynamic environments.
3. Composite Rupture Disc: A composite rupture disc is constructed from multiple layers of material, typically including a sealing layer and a perforated metal support. This design allows for controlled bursts at precise pressure points, making it suitable for applications that require high precision and accuracy in pressure relief.
4. Graphite Rupture Disc: Graphite rupture discs are made from corrosion-resistant graphite material, making them particularly effective in harsh environments. These discs are designed to withstand extreme temperatures and corrosive chemicals, making them ideal for industries such as chemical processing and the oil and gas sectors, where resilience to harsh conditions is critical.
5. Sanitary Rupture Disc: Sanitary rupture discs are specially designed for use in clean, hygienic environments. Made from non-contaminating materials, they ensure cleanliness and prevent contamination during operation. These discs are commonly used in the food, pharmaceutical, and biotech industries, where maintaining sanitary conditions is essential.
6. Vacuum-Support Rupture Disc: Vacuum-support rupture discs are equipped with a support structure that prevents the disc from collapsing under vacuum conditions. This feature ensures that the disc performs reliably even when subjected to both pressure and vacuum relief requirements, making them suitable for systems where both pressure and vacuum control are critical.
These rupture discs offer various benefits, such as cost-effective pressure relief, reliability, and the ability to prevent overpressure incidents in different environments.
How do Rupture discs work?
Rupture discs are safety devices designed to protect equipment from excessive pressure or vacuum conditions. Here’s how they work:
- Installation: Rupture discs are installed in a piping system or vessel to act as a pressure relief mechanism.
- Normal Operation: During regular operation, the disc remains intact, allowing the system to function under normal pressure conditions.
- Pressure Threshold: Each rupture disc is engineered to burst at a specific pressure. When the system pressure reaches or exceeds this pre-set threshold, the disc bursts.
- Pressure Relief: Once the disc ruptures, it creates an opening that allows the excess pressure to escape safely, preventing damage to equipment or danger to personnel.
- One-Time Use: Rupture discs are a single-use device, meaning that once they burst, they must be replaced to restore the system’s protection.
By relieving overpressure in a controlled manner, rupture discs help prevent catastrophic equipment failure and ensure safe operations.
Where and How Rupture Discs are used
Rupture discs are versatile safety devices employed in various industries and applications. Here’s a breakdown of their uses:
- Single Pressure Relief Device (PRD): Rupture discs can function as standalone pressure relief devices, providing essential protection for vessels and piping systems from overpressure.
- Multiple PRD Systems: In some applications, rupture discs are used in conjunction with other pressure relief devices. This configuration enhances safety and reliability by providing multiple layers of protection against excessive pressure.
- Fire Condition Applications: Rupture discs are also effective in fire condition scenarios. They can be installed in systems that may be exposed to high temperatures, allowing for the safe release of pressure when heat causes the contents to expand.
FM-200 Rupture Disc
FM-200 rupture discs are pressure relief devices specifically designed for use in FM-200 (HFC-227ea) fire suppression systems. These systems use FM-200 gas as a clean agent to extinguish fires quickly without causing harm to equipment or the environment. The rupture disc plays a crucial role in maintaining the integrity and safety of the fire suppression system by preventing overpressure within the storage container.
When the internal pressure of the FM-200 container exceeds the rated burst pressure, the rupture disc activates, releasing the excess pressure to protect the cylinder from damage. The disc’s fast response ensures that the system remains safe and functional without compromising the fire suppression agent’s containment. FM-200 rupture discs are commonly used in environments like data centers, server rooms, and other spaces where sensitive equipment needs fire protection without risk of water damage. The rupture disc ensures that pressure is safely managed, enhancing the overall reliability of the fire suppression system.
Accessories for Safety Valves and Rupture Discs
Accessories for safety valves and rupture discs play an important role in optimizing performance and ensuring the proper functioning of pressure relief systems. Common accessories include:
- Burst Indicators: These devices signal when a rupture disc has burst, helping operators quickly identify a pressure relief event.
- Valve Position Indicators: Installed on safety valves, these accessories provide real-time feedback on the valve’s status, ensuring proper monitoring of system pressure.
- Pressure Gauges and Sensors: Used to measure system pressure and detect any abnormal conditions that may require intervention.
- Holders and Assemblies: Specially designed to secure rupture discs and ensure their proper installation within piping systems or vessels.
- Pressure Relieving Devices (PRDs): Used in combination with rupture discs and safety valves to provide additional layers of protection.
