Pre-Torque multiflange IG-KUB®-PTU rupture disc holder

The unique design of the IG-KUB®-PTU rupture disc holder always guarantees proper insertion, and enables the pre-assembly of the rupture disc. This avoids damaging the rupture disc, which can then be reused after dismantling, for example, within the scope of an inspection.

The IG-KUB®-PTU rupture disc holder is a flat-seat holder for reverse acting rupture discs. The sealing edge of the seat surface ensures leak-free sealing through a fully-metallic clamping. The inside diameter of the rupture disc holder outlet performs a support  function and guarantees the optimal opening behaviour when the defined burst pressure is reached.

The integrated pre-assembly bolts allow easy and safe rupture disc installation. The holder can be used for a wide range of flanges and various pressure classes.

Your advantages

  • Pre-assembly of the rupture disc for a rugged and secure handling with a defined torque.
  • Multi-flange design, suitable for different pressure classes and flange systems.
  • High degree of leak-tightness through a full-metal sealing.
  • Available in a wide variety of materials.
