Understanding Rupture Discs

A rupture disc, also referred to as a bursting disc or a pressure safety disc, is a thin, circular device designed to rupture at a predetermined pressure. It functions as a failsafe mechanism in pipelines, alleviating excess pressure to prevent system overpressure and possible rupture. Depending on the specific application and safety requirements, rupture discs are typically installed in conjunction with pressure relief valves (PRVs) or as independent safety devices.

Functionality and Operation of Rupture Discs

The burst pressure or burst rating is the precise pressure threshold at which rupture discs are designed to fail. They are made from materials that can withstand the operating conditions and pressures of the pipeline system. When the pressure exceeds the rupture pressure, the rupture disc is designed to collapse, allowing fluid or gas to escape. This controlled discharge aids in relieving excess pressure and preventing pipeline and related equipment damage.

Pipeline Systems Applications

In a variety of pipeline applications, rupture discs are widely utilised as an essential safety measure. Some important applications for rupture discs include:
