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.
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.
