BURST INDICATORS
Rupture discs are often used as primary pressure relief devices and to isolate pressure relief valves. When used as a primary pressure relief device, burst indication is used to provide instantaneous notification of rupture disc activation.
When rupture discs are used in conjunction with pressure relief valves, they remove valves from contact with harsh process conditions and helps prevent fugitive emissions. In this application, the ASME code, Section VIII, Div. 1, requires that the space between the disk and the valve must be provided with a suitable telltale assembly capable of detecting a rupture or pin-hole leak. Depending on the device selected, Fike burst indicators can be used to activate alarms, bells, remote annunciators or interfaced with process control systems, so that appropriate safety follow-up measures can be taken.
