KUB® Product Information

Product catalog summary
Product Overview: The KUB® rupture disc is a high-performance safety device designed using Euler's critical load formula, making it robust and reliable. It features a unique buckling pin design that ensures full bore opening without creating a weak point, enhancing durability and reducing replacement costs.
Design and Features: The KUB® has a two-layer design with a smooth sealing membrane to minimize corrosion. It boasts a 98% operating ratio and is compatible with various applications, including liquid-only systems. The disc can be easily removed, inspected, cleaned, and reinstalled, extending its lifespan and reducing maintenance costs.
Advantages: Key benefits include its robust design, ease of reinstallation, resistance to damage during handling, and compatibility with a wide range of process conditions. It also extends the lifespan of safety valves by isolating them from process media.
Technical Specifications: The KUB® offers a wide burst pressure range (20 mm to 800 mm) and operates effectively in temperatures from -80°C to 600°C. It is non-fragmenting and suitable for full vacuum and back pressure conditions.
Applications: The KUB® is suitable for use in safety valve isolation, heat exchangers, refineries, chemical and petrochemical industries, power plants, and more.
Certification: The product is certified by various international standards, including PED, ASME, and KOSHA.
Material Options: The rupture disc is available in various materials such as Stainless Steel, Hastelloy, Inconel, Nickel, Monel, Titanium, and Tantalum, each with specific burst pressure parameters.

KUB® Product Information-1

PRODUCT INFORMATION GBPI-KUB-20171/1 | © REMBE® | All rights reserved | Valid from 02.11.2020 | Subject to technical changes without notice Reverse acting rupture disc ENGINEERED TO LAST: ROBUST, HIGH PERFORMANCE, RUPTURE DISC SOLUTION Your advantages 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. • Virtually immune to damage during installation, transport or storage – maximises process uptime and unnecessary replacement costs. Boasting a 98% operating ratio, the KUB® is not subject to fatigue even at higher operating pressures* and in the most demanding of process conditions in vapour, gas, liquid or two-phase applications. Unlike many other reverse acting discs, the unique construction of the KUB® makes it fully compatible with liquid-only applications, maximising installation points which can benefit from this rupture disc, simplifying customers' installation, maintenance and purchasing routines. • Unique buckling pin element – creates the most robust rupture disc design available. • Reinstall and reuse with ease after inspection – guarantees maximum lifespan of one rupture disc, reducing spares costs. •E xtend safety valve lifespan – robust design protects valves from process media, reducing corrosion risk and maximising overall investment. • Widest size and burst pressure range in a single reverse acting disc – one-disc type suitable for a wide range of process conditions, improving purchasing, inspection and maintenance routines. •C ompatible with liquid-only applications – maximises installation points where the benefits of this technology can be achieved. *Depending on the specific application. REMBE® Innovation – unique in the market: The KUB® rupture disc has a robust design and can be removed, inspected, cleaned and reinstalled. Any damage is easy to detect with the naked eye.

KUB® Product Information-2

PRODUCT INFORMATION Inspect and reinstall with ease 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. 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...
