KUB® Reverse Acting Rupture Disc

Robust reverse acting rupture disc using buckling pins sized by Euler's formula, for vapour, gas, liquid and two-phase service.

Description

The KUB® burst pressure is determined using Euler's critical load formula via a series of buckling pins that collapse for reliable full-bore opening.

Key features

  • No weak point in the metal, making it highly resistant to handling damage
  • Two-layer design with a smooth sealing membrane facing the process
  • Suitable for vapour, gas, liquid and two-phase applications
  • Withstands full vacuum and back pressure
  • Can be installed upstream of a safety valve to protect it
  • KUB® V series allows in-situ safety valve testing

Applications

Overpressure protection of pressure vessels, piping and safety valves in process and energy installations.
