flat-seat holder

for reverse acting rupture disks for a leak-free seal.

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

The sealing edge of the seat surface ensures a 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 an easy and safe installation of the rupture disc. The holder can be used for a wide range of flanges and various pressure classes.

Advantages

Multi-flange design, suitable for different pressure classes and flange systems.
High degree of leak-tightness through a full-metal sealing.
Available in a broad variety of materials.
Designs for different pressure ranges and companion flange types.
Connections for pressure monitoring of disc assembly is optional.
Reusable holder.
Metal-to-metal sealing.
Standard materials: stainless steel, 1.4301, 1.4404, 1.4435, 1.4571, 1.4539, hastelloy C, titanium, nickel, inconel.
