KUB^® F

for installation directly between flanges.

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.

signalling devices

Automated processes use intelligent signalling systems to keep you informed at all times about the status of your entire plant and any faults that may arise. You can even install signalling devices for rupture discs that have already been installed.

product overview

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.

Inspect and reinstall with ease.

Simple to install, the KUB^® is also extremely easy to remove and reinstall during routine cleaning or maintenance checks without concerns of damaging the disc. Installed into an IG-KUB^® Holder, the KUB^® is a torque-independent design which uses a leak-tight, metal-on-metal seal, which allows the rupture disc to be reinstalled and used safely after inspection. REMBE^®'s torque independent designs are resistant to damage caused during installation which increases the ability to get the process back up and running as quickly as possible without concerns that the burst pressure may have been affected. With no special installation tools required, the KUB^® provides fast, simple installation with accurate pressure relief for minimal downtime. With one of the widest burst pressure and size ranges for a reverse acting rupture disc (20 mm to 800 mm) the KUB^® is the ideal solution for a wide range of challenging industrial processes. The broad pressure range allows many different processes to be equipped with just this one type of rupture disc. Only one holder system is required for all REMBE^® reverse acting rupture discs. If the process conditions change in future, e.g. the burst pressure, only the rupture disc needs to be replaced. Used together with REMBE^®'s reusable NIMU detection system for a full rupture disc assembly, ensuring reliable notification in the event of disc burst.

Tobias Frigger and Winfried Göddecke, laser and KUB^® specialists

"We use state-of-the-art laser machines to cut the buckling pins on the KUB^®. This is followed by tests on the rupture discs. The KUB^® is an absolute must for anyone wanting a good high-quality rupture disc – one that lasts and a disc which is robust, in particular."
