Fike SRX rupture disc is a reverse acting rupture disc with a cross scored design for use with vapor services only. These discs have many high performance characteristics that make them ideal for demanding applications such as the isolation of pressure relief valves.
Features
  • SRX rupture discs have superior service life in heavily pulsating and cyclic duty when compared to forward acting (tension loaded) rupture discs. This is primarily due to the reverse buckling (compression loaded) design
  • The SRX is designed to be non-fragmenting. The cross score configuration controls the disc opening and enables the disc to rupture without fragmentation
  • SRX discs will sustain process operating pressures as high as 90% of the marked disc rating, without premature failure due to metal fatigue
  • The SRX will withstand full vacuum, or back pressure service in magnitudes equivalent to the stamped burst pressure
  • SRX discs perform reliably even under less than ideal installation conditions due to their special seating configuration
  • 316/316L SST, Inconel® 600, Monel 400, Nickel 200/201, and Hastelloy® C276 are available as standard materials of construction
  • The DiscLoc locator tab prevents incorrect, inverted installation in the holder. Prominent flow arrows indicate the process flow direction during venting
