The back cover listsspecific addresses and phone numbersto help locate the representativenearest Role ofRupture DiscsRupture discs are non-reclosingpressure Relief devices which open withinmilliseconds when system pressurereaches its specific burst rating. 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.

3 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 COMBINATION series with a Pressure Relief valve OR As a QUICK OPENING device for Pressure transferContinental Disc Corporationmanufactures and tests under anISO 9001 Certified Quality your needs include specialor exotic materials, ultrahigh or ultralowburst pressures, our Engineering,Manufacturing and Testing facilitiesare ready to serve your SERVICE2 CUSTOMIZED TECHNOLOGY3 There 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). 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 RangeManufacturing Range is defined asthe allowable Pressure range withinwhich a rupture disc is is basedupon the customer specified burstpressure.

4 After the rupture disc hasbeen manufactured and tested, it isstamped with the rated burst 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 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 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 to the table below for theapplicable manufacturing rangeand burst tolerance for Tension andReverse Acting rupture disc :1.

6 Manyapplications require high pressuresystems in order to obtain specificchemical reactions. Many varietiesof mating connections are availableto meet the high Pressure sealingrequirements of processing systems,as shown in photo A 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 . maintains a completestock of coil and sheet materials ingraduated thicknesses, including 316 Stainless Steel, Monel, * Nickel, Inconel, *and Hastelloy C ** to supply the burstpressure requirements of our alloys such as titanium, tantalumor niobium are also 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 C shows three non-fragmentingdesign units.

In photo E , a threaded designis used, encapsulating the replaceablerupture disc within an aluminum light weight characteristics ofaluminum make it possible to meetthe weight restriction unique applications aredeveloped for one-time use and arethrown away when the rupture disc hasburst. The assembly in photo F is athrowaway unit and provides protectionfor a Pressure blanket on electronicscomponents. Titanium and other exotic alloys arefrequently required for the advancedtechnology applications of the defenseand aerospace industries. Photo G is a welded reverse acting rupture discassembly used in a fuel generationsystem. This rupture disc assembly isthe primary safety component used incase of an overpressure condition.
