The toughest, highest performing bursting disc on the market.
The KUB® is the only rupture disc to be manufactured using Euler's critical load formula to determine the burst pressure, creating the most robust, high-performance rupture disc available. Unlike other rupture disc solutions where a weak point is created in the metal, the KUB® is a unique, highly engineered solution, benefiting from a series of buckling pins which accurately collapse for reliable, full bore, opening. As there is no specific weak point on the rupture disc, the KUB® is an extremely robust solution, almost immune to damage by incorrect handling, improper installation or even being dropped! This maximises the lifespan of the disc and minimises long-term investment by lowering ongoing replacement costs. The KUB® features a two-layer design, with the smooth, unblemished surface of the sealing membrane facing the process minimising the possibility of damage due to corrosion.
For burst pressures of up to 1 barg, the KUB® F can be installed directly between flanges in a variety of applications. This makes it ideal for applications in which reliability and a precise design pressure in the low pressure range are essential.
Extend safety valve lifespan.
Suitable for full vacuum and back pressure resistant, the KUB® with its non-fragmenting design can be installed upstream of a safety valve to isolate the valve from the process. When used in combination, the KUB® will ensure the best possible condition of the safety valve, significantly extending service intervals and overall life of the valve while maximising return on investment. The leak-tight design prevents emissions and the associated costs whilst protecting the safety valve from corrosive, aggressive or adhesive media allowing for the use of safety valves in more cost-effective materials. The special KUB® V series rupture disc allows for in-situ testing of the safety valve.
Advantages
- High working pressure ratios.
- Direct installation between flanges.
- Suitable for aseptic requirements due to the extremely smooth surface in the sealing part.
