KUB® is not only extremely easy to install – it is also simple to remove and reinstall. In addition to a standard operating pressure ratio of up to 98% (depending on the specific application), the design is robust enough to cope with incorrect handling before and during installation. The IG holder also helps in this regard. The rupture disc and holder are designed to ensure that it is impossible to insert the rupture disc incorrectly. KUB® does not use bite-type seals. Instead it uses a leak-tight, metal-on-metal seal, which allows the rupture disc to be reinstalled after inspection.
The rupture disc KUB® is the ideal solution for a wide range of challenging industrial processes with low to high operating pressures or vacuum, e.g. in gas, liquids or vapour applications as well as
in two-phase flow applications. Its broad pressure spectrum allows you to equip many different processes seamlessly with just this one type of rupture disc – a major advantage: only one disc holder system is required. If the process conditions change (e.g. a different operating pressure), you can simply replace the rupture disc and continue to use the same holder. That saves money!
