Rupture disks

Miniature rupture disk assemblies are designed to improve equipment safety, reliability and longevity for engine-powered equipment markets and fluid power applications.

BS&B Safety Systems of Tulsa, Okla., said the assembly includes the rupture disk and housing and is custom engineered to work with the user’s desired interface to the pressurized equipment. The devices are typically threaded or flanged. The rupture disk and holder are combined by the manufacturer by based on the application conditions and leak tightness requirements.

In industries such as oil and gas, said BS&B, components such as accumulators require rupture disks. Accumulators hold hydraulic fluid under pressure. If the pressure spikes too high, there is a risk that without a rupture disk the system, or even accumulator, could experience a catastrophic failure, said the company.

Available ready-to-use and with no assembly required, integrated units are certified as a device to perform at the desired set pressure. The one-piece design allows for easier installation and quick removal if the rupture disk is activated, said the company.
