The Fike SRL rupture disc is reverse-bulged and perimeter-scored to facilitate opening without knife-blades. It is ideal for such demanding applications as the isolation of pressure relief valves. Sophisticated finite element analysis (FEA) techniques were used to develop the SRL’s Contour Modified™ design.
Features
  • SRL rupture discs can be used in a wide variety of applications including liquid, vapor and two phase media flow
  • SRL can operate up to 90% of its marked burst pressure for burst pressures over 40 psiG (2.76 BARG), and up to 90% of the minimum of the burst tolerance at 40 psiG (2.76 BARG) and below
  • SRL will withstand full vacuum without the aid of a vacuum support (see performance attributes)
  • If damaged during normal installation, the rupture disc will open at less than 1.5 times the stamped burst pressure
  • SRL discs perform reliably even under less-than-ideal bolt loading conditions due to their special seating configuration
  • The perimeter score configuration, along with the integral ring, control its opening and enable the disc to rupture without fragmentation
  • The single hinge design helps achieve low burst pressure and full opening upon rupture
  • The DiscLoc locator tab prevents incorrect, inverted installation in the holder. Prominent flow arrows indicate the process flow direction during venting
