Available in all standard materials, in all flange assemblies and ANSI ratings; standard, composite or reverse
buckling discs.
APPLICATION:
Zero Leakage - A must with toxic contents or very valuable contents. Extremely corrosive conditions
or damage could cause the process exposed rupture disc to leak. A pressure gauge in the midflange would indicate the leak, while a second rupture disc maintains the system leak free. The first
rupture disc could then be changed out at an opportune time.
Quick - Opening Device - By pressurizing the space between the two rupture discs in a Double Disc
Assembly, one can obtain a quick opening device. Upon dumping the pressure between the two
discs, full open area is obtained within a few milliseconds. The Double Disc Assembly, as a quick
opening device, has been used in activating pressure systems, and to test systems for sudden
pressure changes. Formulas on reverse side.
Reaction Starter - The Double Disc Assembly has been used in applications such as testing liquid
media which ignites on contact. In this situation, mixing two fuels prematurely could cause an
unwanted explosion. By use of a Double Disc Assembly, the fuels could be contained separately until
the Double Disc were activated to release the fuels into the system for ignition.
PRICE - 1-3/4 times single disc assembly of same assembly, material and rating.
DELIVERY - Same as standard assembly of same size and material.
TECHNICAL DATA - See reverse side for how it works and design notes.
