Pressure Relief via FDC’s type KSRSR Reverse Acting Rupture Discs
FDC’s type KSRSR Reverse Acting Rupture Discs
Purpose
To prevent dangerous incidents to industrial processes, personnel, and environment due to an overpressure, exothermic/runaway reaction, or explosion. The FDC rupture discs are used for overpressure protection for various applications in accordance to AS1358, ISO 4126, & ASME Section VIII standards.
Applications
Applications in pressurised vessels, reactors, heat exchangers, distillation columns, pump and line protection and alternative to relief valves in industrial facilities.
