Reverse Buckling Rupture Disk - SKr™

  • The SKr™ Reverse Rupture Disk (Bursting Disc) is designed with a circular score line located at the edge of the domed area, on the downstream side of the disk. At the marked burst pressure, the disk's dome reverses and opens by shearing around the circular score line.
  • The SKr™ Reverse Rupture Disk (Bursting Disc) uses SAF- technology (Structural Apex Forming) enabling very low burst pressures to be achieved with excellent opening characteristics
  • An integral energy absorbing hinge located on the downstream side of the disk enables the SKr™ Reverse Rupture Disk (Bursting Disc) to perform in gas or liquid service with superior flow performance.
  • The hinge design interacts with the Safety Head bore to retain the SKr™ Reverse Rupture Disk (Bursting Disc) on opening, avoiding fragmentation
