They are designed to relieve eitherpositive or negative conditions at aspecified set pressure and in someapplications, additionally withstandvacuum or backpressure. Rupture discsmay also be designed to provide dualrelief (positive or negative) within thesame rupture disc. A rupture disc opens (relieves)within milliseconds. This instantaneousand unrestricted relief capacity allowsthe rupture disc to be used:? As the PRIMARY relief device? As a SECONDARY relief device to a pressure relief valve? As a relief device in COMBINATIONseries with a pressure relief valve OR? As a QUICK OPENING device for pressure transferContinental Disc Corporationmanufactures and tests under anISO 9001 Certified Quality System.Whether your needs include specialor exotic materials, ultrahigh or ultralowburst pressures, our Engineering,Manufacturing and Testing facilitiesare ready to serve your needs.WORLDWIDE SERVICE2CUSTOMIZED TECHNOLOGY3There are two basic designs of rupture discs that can be configured into many different envelope packages to suit your application, Tension Type discs and Reverse Acting discs. Both designs are compatible for seal welding (Hermetic Seal).C.D.C. manufactures rupture discassemblies with pressure ranges from6? water column to 80,000 psig and fortemperature conditions from cryogenicto 1000°F. Depending upon the typeof rupture disc used, TENSION orREVERSE ACTING, a manufacturingrange and burst tolerance is applicable.Manufacturing RangeManufacturing Range is defined asthe allowable pressure range withinwhich a rupture disc is rated. It is basedupon the customer specified burstpressure. After the rupture disc hasbeen manufactured and tested, it isstamped with the rated burst pressure.The rated (stamped) burst pressure isestablished by bursting a minimum oftwo discs and averaging the pressureat which the rupture discs burst. Thisaverage is the rated (stamped) burstpressure of the rupture disc.Burst ToleranceIn accordance with ASME Code, atolerance is applied to the rated burstpressure of a rupture disc. The ratedor stamped burst pressure is establishedafter the rupture disc has beenmanufactured by testing a minimumof two rupture discs and averaging thepressure at which each rupture discbursts. This average is the rated(stamped) burst pressure. A toleranceis then applied to this pressure todetermine the maximum expectedvariation from the rupture disc?srated (stamped) burst pressure.As per ASME Code, a rupture discis designed with a burst tolerance of –2psig for pressures under 40 psig and–5% for pressures 40 psig and above.Refer to the table below for theapplicable manufacturing rangeand burst tolerance for Tension andReverse Acting rupture disc designs.NOTES:1. Special reduced manufacturing ranges can be obtained. 1/2, 3/4 or min/max ranges are available upon request. Please consult your Continental Disc Corporation representative or the factory for additional information.2. Burst tolerances are the maximum expected variation from the rupture disc?s rated (stamped) burst pressure.3. Continental Disc Corporation can manufacture rupture discs to complywith ASME Code requirements.TENSION TYPE:? Operation to 80% of burst rating? Available in non-fragmenting design?

Many varietiesof mating connections are availableto meet the high pressure sealingrequirements of processing systems,as shown in photo ?A ? below.High pressure rupture discassemblies used in the plastic andrubber extrusion industry often requirematerials from one mil (.001?) to sheetor plate thickness. Some examplesare shown in photo ?B ? .C.D.C. maintains a completestock of coil and sheet materials ingraduated thicknesses, including 316Stainless Steel, Monel,fi* Nickel, Inconel,fi*and Hastelloy Cfi** to supply the burstpressure requirements of our customers.Exotic alloys such as titanium, tantalumor niobium are also available.Non-Fragmenting DesignsContinental Disc Corporation has theexperience, technology and manufactur-ing techniques to provide rupture disc invarious sizes and shapes designed fornon-fragmentation This design mayinvolve a variety of scoring techniques,passive and active mechanical openingdevices or petal retention designs.Photo ?C ? shows three non-fragmentingdesign units. C-1 and C-2 are reverseacting ?replaceable? rupture discassemblies. C-3 is a cross scoredtension type design, suitable as a?Quick Opening? relief device actuatedby an independent means.Hermetic SealsVarious weld designs and methodsare used to achieve sealing betweenthe rupture disc and body assembly.Examples in photo ?D ? are pressureplugs used in hydraulic and liquidapplications. The rupture disc is weldedto the top of a specially designed bodyplug. Weld seals are used when leak-age is of critical concern. Weld sealintegrity can be tested at C.D.C. byMass Spectrometry to sensitivity levelsof 1 x 10-9 Atm. cc/second helium.4DACBTypical applications:Aircraft Tire /Wheel AssembliesNitrogen Gas Springs/ ManifoldsPneumatic Air DryersTypical applications:Rubber, Plastic and Composite Material Extrusion MachineReactor Vessel Process Piping (Petrochemical/Power Industry)Marine and Offshore Piping/Vessel Pressure ReliefTypical applications:Down-hole Drilling System (Liquid)Specialty Valves for Aircraft Oxygen Systems (Gas)Missile/Rocket Pressure Vessel Relief (Gas)Aircraft Evacuation Systems (Gas)Typical applications:Gas Panels for Purity /Toxic GasMissile /Rocket Quick-Opening ValveAir Conditioning/Refrigeration Storage VesselsAir /Hydraulic Accumulators and CompressorsAutomotive/Aircraft Safety Restraint SystemsC-1C-2 C-3NOTE: All products were photographedon a 1/4? grid for scale.* Monel and Inconel are registered trademarks of the Inco family of companies.** Hastelloy is a registered trademark of Haynes International.CUSTOMIZED FOR SPECIFIC NEEDS5Unique ApplicationsIn aerospace and aircraft applica-tions, weight restrictions of systemcomponents often dictate the type ofrupture disc design and/or materialsused.
