Rupture discs are safety devices used for pressure relief in many different applications throughout the  industrial life science markets. Rupture discs have a defined breaking point that responds to a set pressure, preventing deflagrations and deformations in a system caused by overpressure. Rupture discs are dome shaped, non-reclosable devices that produce a leak-proof seal until a preset pressure level bursts the seal, preventing explosions that may otherwise cause casualties and catastrophic damage to a facility’s equipment.

What Are The Advantages Of Using Rupture Discs?

Along with safety valves, rupture discs are one of the most commonly used pressure protection devices used in industrial manufacturing applications. Rupture discs’ primary advantage over electronic, pneumatic, and spring loaded safety systems is that they are failsafe, as long as they’re made with high quality materials and are properly installed. Although rupture disc technology has improved immensely in recent years, they are still a relatively simple mechanism when compared to other safety devices. This makes them highly economical and one of the most important safety systems in any industrial application!

How Do Rupture Discs Work?

Rupture discs operate under the principle of tensile strength, which is the resistance of a material to breaking under tension. When the weakest portion of the disc exceeds its tensile strength, also known as the breaking point, it will rupture, preventing explosions and other damage caused by overpressure. There are several different types of rupture discs designed specifically for different applications and industries: Forward-Acting Rupture Discs, Reverse-Acting Rupture Discs, Compact Rupture Discs, and Hygienic Rupture Discs. The difference between forward-acting and reverse-acting rupture discs is the direction the dome faces; in forward-acting rupture discs, the dome faces toward the process, while in reverse-acting rupture discs, the dome faces away from the process. Hygienic Rupture Discs are designed to meet the sanitary requirements often needed for systems in the biotech, pharmaceutical, food & beverage, and other life science industries.
