Rupture devices are a type of safety device used to prevent damage that could be caused to a vessel or pipeline by overpressure or vacuum. Rupture discs are single-use pressure relief devices, because once they have burst, they need to be replaced completely. There are three main types of rupture discs: forward-acting (also known as tension loaded) rupture discs, reverse-acting (also known as compression loaded) rupture discs, and graphite (also known as shear loaded) rupture discs. In this article, we’ll talk more about how exactly rupture discs work, and what their advantages & disadvantages are! If you have any questions about rupture discs or any other safety devices used in manufacturing applications, please contact our team at Safety Systems Inc. today!

How Do Rupture Discs Work?

As mentioned above, rupture discs are used to install overpressure & vacuum events in pressure-containing vessels and pipelines. Rupture discs are installed on the exterior of a vessel and have a set tensile strength breaking point. When pressure exceeds this breaking point, the rupture disc will instantly burst, releasing pressure from inside the vessel, preventing damage to the vessel and facility that could otherwise be caused by an overpressure event. Rupture discs are essential safety devices in a wide range of manufacturing applications, including those in the chemical, oil/gas, pulp/paper, water, pharma, biopharma, brewing, and food processing industries!

Advantages & Disadvantages Of Rupture Discs

One primary advantage of a rupture disc is that they are simple devices that do not have any moving parts or highly technical elements, so as long as they are manufactured and installed correctly, they are incredibly reliable at preventing overpressure events within a vessel. Another advantage of a rupture disc is that they require next to no maintenance because of their simplicity!

One of the only disadvantages of a rupture disc is that they are single use. Once the rupture disc bursts during an overpressure event, it will need to be replaced completely. One more disadvantage of rupture discs is that they need to be handled and installed extremely carefully, as even the smallest amount of damage during installation can alter a rupture disc’s pressure breaking point.
