Continental'sComposite Rupture Discs are designedto provide instantaneous, full-openingpressure relief.Continental Disc offers twoComposite Type rupture disc designstyles, a preformed style, like the CDC orPLV Rupture Disc; and a flat style, likeC.D.C.'s ENVIRO-SEAL Rupture Disc.Preformed CompositeRupture DiscA Preformed Composite Rupture Discconsists of two or more components ofmetallic or non-metallic materials. Thesecomponents generally include a metallictop section, a metallic or nonmetallicseal member, and an optional vacuumsupport.Preformed CompositeRupture Disc Features:• Excellent performance in lowpressure applications• Operation to 80% of the rupturedisc's rated (marked) burst pressure• For use in gaseous or liquid service• Made from a variety of corrosionresistant materials• Non-fragmenting design when usedwith a non-metallic seal• Ideal for use under a safety reliefvalve to isolate the valve fromprocess media• Provided with Continental's uniqueThree-Dimensional Flow DirectionTag as a standardUnique Seven-HoleDesignContinental's Preformed CompositeRupture Discs also feature our seven-hole pattern, positioned at the apex ofthe rupture disc's top section. Thisunique configuration, in combination withthe pre-cut sections along the dome,provide non-fragmenting characteristicswhen used with a non-metallic orTEFLON®** seal. By using this seven-hole design, thicker, more durable mate-rials can be used to manufacture therupture disc while still achieving the high80% operating-to-burst-pressure ratio.Various seal material options, suchas TEFLONS and exotic metals, helpinsure excellent corrosion resistance.Continental's non-metallic seals areessential to minimize fragmentation.When ordering, please specify if yourapplication requires a non-fragmentingrupture disc.RecommendedOperating ConditionsContinental's Preformed CompositeRupture Discs can be used in a varietyof applications, including equipmentoperating at up to 80% of the rupturedisc's rated (stamped) burst pressureand systems having either liquid or gasprocesses.Under ideal operating conditions,such as static pressure and a tempera-ture well below the maximum recom-mended for the rupture disc materialused, Preformed Composite RuptureDiscs may be subjected to operatingpressures exceeding 80% of the rated(stamped) burst pressure. Contact thefactory for additional information aboutthe use of a Composite Rupture Discabove this 80% operating ratio.Sizes and MaterialsSizes ranging from 1" through 30"(25mm to 750mm) are available withburst pressures from 1.5 psig to 1440psig (0,10 barg to 100 barg). Because ofthe availability of a variety of seal materi-als, these rupture discs can be used inservice temperatures of up to 1000°F(542°C) and can resist most corrosiveand atmospheric conditions. The metallictop section can be manufactured fromvarious materials to meet the needs ofeach individual application.** TEFLON is a registered trademark of E.I. du Pont de Nemours and Company used under license.2Table VI - 30° Insert Holder Weights and Dimensions16"400mmWEIGHTS AND DIMENSIONS1211NOTE: Consult factory for availability of flange classes or sizes not listed.ANSI DIN JIS Height WeightNominalSize Class Outside Dia.

Many variablessuch as pulsations, cycling, and oper-ating-to-burst-pressure ratio must beconsidered in order to achieve maximumservice life from the rupture disc.Versatile operating characteristics,along with numerous customizableoptions like protective liners, protectiverings, vacuum or backpressure support,gaskets, and Continental's exclusiveB.D.I.® (Burst Disc Indicator) AlarmSystem provide a comprehensiveselection to match Preformed CompositeRupture Discs with a wide range ofsystem protection applications.Seating ConfigurationsPreformed Composite Rupture Discsare available in a 30° angular "Light Lip"seat for normal operating pressures andin a "Flat Seat" design for superiormetal-to-metal sealing. Refer to C.D.C.Bulletin 2-2203-2 for details.Corrosion ProtectionThe design of Continental'sPreformed Composite Rupture Discsallows the use of highly corrosionresistant seal materials. This is possiblebecause the burst pressure rating of therupture disc is determined by the slottedmetal top section. Therefore, the seal orliner can be made from thin materials ofanything from TEFLON to silver or goldand still provide a wide range of burstpressures – economically.Protective RingsProtective rings may be used onrupture discs made of thin materials orwhere delicate seals are used. Theserings provide rigidity for easier handlingand also help protect the rupture discfrom foreign materials in the seatingarea, where a rupture disc holder mayhave become pitted or corroded fromextended use.Vacuum Support,Backpressure SupportIn some burst pressures andmaterials, it is necessary to support arupture disc when system backpressureoccurs. Vacuum supports for PreformedComposite Rupture Discs, manufacturedfor and directly attached to the rupturedisc, are available to withstand a fullsystem vacuum to 14.7 psig (1,01 barg).For backpressures in excess of fullvacuum, C.D.C. can supply abackpressure support specificallydesigned for your operating conditions.When ordering a PreformedComposite Rupture Disc that will besubjected to a vacuum condition, clearlyspecify the conditions that the rupturedisc will encounter. C.D.C. will supply theapplicable support.Three-DimensionalFlow Direction Tag*Continental's innovative Three-Dimensional Flow Direction Tag providesinstant visual verification that the rupturedisc has been correctly oriented into thesystem. The 3-D tag extends beyond theholder to insure clear visibility for easierinstallation and inspection after therupture disc has been installed.3Protective Ring(Optional )Top SectionSealSlot CoverVacuum Support(Optional )* Rupture disc tags are not attached to rupture discs for use in Screw Type or Union Type Holders. Tags can beattached to a rupture disc for use in Union Type Holders when specified. Consult the factory for more information.COMPOSITE TYPE RUPTURE DISCALARM SYSTEMPreformed CompositeRupture Disc TypesContinental Disc manufacturesseveral Preformed Composite RuptureDiscs to fit numerous applications.CDC TypeThe CDC Type Rupture Disc is thebasic Preformed Composite RuptureDisc design consisting of a slottedmetallic top section and a TEFLON ormetallic seal on the top section's processside. This basic design providescorrosion protection and excellentperformance in low pressure applicationswhere no backpressure or vacuum isexpected.CDCV TypeThe CDCV Type Rupture Disc is thesame design as the CDC Type RuptureDisc, with the addition of a vacuumsupport installed on the process sideof the seal. This design provides processside corrosion protection and support forfull vacuum conditions.PL and PLV TypeThe PL Type Rupture Disc is similarto the CDC type, with the addition of acorrosion resistant TEFLON liner placedon the outlet side of the top section.The PLV Type Rupture Disc is thesame design as the PL Type RuptureDisc, but with the addition of a vacuumsupport. The vacuum support on thisdesign, however, is located on the outletside of the top section. The outlet liner ispositioned above the vacuum support,protecting the metallic top section andthe vacuum support from corrosiveelements in the atmosphere.B.D.I.* (Burst Disc Indicator)Alarm SystemIn situations where immediatenotification of pressure relief is critical,Continental's B.D.I. (Burst Disc Indicator)Alarm System should be used toautomatically notify system operatorsthat a rupture disc has burst.The heart of the B.D.I. Alarm Systemis the B.D.I. Alarm Strip, a closed-pathelectrical strip adhered to a TEFLONmembrane, which installs in conjunctionwith the rupture disc. When the rupturedisc bursts, the alarm strip is severed,disrupting the electrical current suppliedfrom a connected monitoring device.This "open-circuit" creates a signal toinitiate alarms or equipment controlledby the monitoring device.The B.D.I. Alarm Strip is computercompatible, resistant to corrosives,and operational over a wide rangeof temperatures.Continental Discalso offers a full lineof B.D.I. AlarmMonitors providingseveral beneficialfeatures includingvisual and/or auditoryalarm signals, aswell as multi-channelmodular designs.Intrinsically safedesigns are alsoavailable. (Refer toC.D.C. Bulletinno. 5-7701-5)4Manufacturing RangeThe manufacturing range is definedas the allowable pressure range withinwhich a rupture disc is rated. It is basedupon the customer specified burstpressure. The manufacturing ranges forContinental's Preformed CompositeRupture Discs are outlined in Table I.Special reduced manufacturing rangesare available upon request including25%, 50%, and 75%. Please consultyour C.D.C. representative or the factoryfor additional information.Burst ToleranceIn accordance with ASME Code, atolerance is applied to the rated(marked) burst pressure of a rupturedisc. The rated (marked) burst pressureis established after the rupture disc hasbeen manufactured by testing aminimum of two rupture discs andaveraging the pressure at which eachrupture disc bursts. This average is therated (marked) burst pressure. Atolerance is then applied to this pressureto determine the maximum expectedvariation from the rupture disc's rated(marked) burst pressure.As per ASME Code, the preformedComposite Rupture Disc is designedwith a burst tolerance of ±2 psig (0,138barg) for pressures up to and including40 psig (2,76 barg) and ±5% for burstpressures above 40 psig (2,76 barg).Burst tolerances for Composite RuptureDiscs rated below 15 psig (1,03 barg)are outlined in Table I. The bursttolerance applies only to the rated(marked) burst pressure on the rupturedisc.Recommended TemperaturesIn general, burst pressures willdecrease as operating temperaturesincrease.

The ENVIRO-SEALRupture Disc is designed to provideeconomical protection for low pressureatmospheric storage vessels and toisolate the downstream side of pressurerelief valves and other equipment fromcorrosive environments.ENVIRO-SEALRupture Disc Features• Excellent performance in lowpressure applications• Operation to 50% of the rupturedisc's rated (marked) burst pressure• For use in gaseous or liquid service• Non-fragmenting design• Ideal for use in isolating thedownstream side of a pressurerelief valve from process media• Provided with a Three-DimensionalFlow Direction Tag as a standardThe ENVIRO-SEAL Rupture Disc istypically used as a corrosion barrier orenvironmental seal. It is a flat Compositestyle rupture disc that installs betweenstandard bore ANSI, DIN, or JIScompanion flanges.The components of the ENVIRO-SEAL Rupture Disc typically consist of ametallic top section and a non-metallicseal on the process side, on both theprocess and the vent side, or betweentwo metallic top sections.The top section of the ENVIRO-SEAL Rupture Disc is designed fornon-fragmentation, utilizing Continental'sseven-hole pattern.As a standard, the ENVIRO-SEAL ismanufactured from 316 Stainless Steel,TEFLON seals, and a non-asbestosgasket on both sides of the rupture disc.Standard sizes range from 2" (50mm)through 36" (900mm).ENVIRO-SEALRupture Disc TypesContinental Disc manufactures threetypes of ENVIRO-SEAL Rupture Discs tofit various applications.ENVIRO-SEAL Type IThe ENVIRO-SEAL Type I RuptureDisc is designed to burst in only onedirection. The rupture disc consists of asingle metallic top section located on thevent side of the rupture disc with a singlenon-metallic seal located on the processside of the rupture disc. The ENVIRO-SEAL Type I Rupture Disc providesexcellent protection and corrosionresistance for applications requiringsingle direction overpressure protection.ENVIRO-SEAL Type IIThe ENVIRO-SEAL Type II RuptureDisc is designed to burst in either thepositive or vacuum direction, at the sameburst pressure. Seal material is locatedon both the vent and the process sidesof a single top section, providing acompletely lined rupture disc. Thisfeature provides a durable corrosionbarrier from both process media andatmospheric corrosives while maintainingdual direction protection.ENVIRO-SEAL Type IIIThe ENVIRO-SEAL Type III RuptureDisc is also designed to burst in eitherthe positive or vacuum direction at thesame burst pressure. However, theENVIRO-SEAL Type III Rupture Discconsists of two metallic top sections,one located on the process side andone on the vent side of the rupture disc.A single seal is located between the twotop sections.The two top section configurationof the ENVIRO-SEAL Type III RuptureDisc design results in a durable lowpressure protection design withenhanced performance under non-staticpressure conditions.ENVIRO-SEAL Rupture DiscSpecificationsThe ENVIRO-SEAL Rupture Disc isnot preformed, therefore, its maximumoperating pressure is limited to 50% ofthe burst rating of the rupture disc.ENVIRO-SEAL Rupture Discs arestamped with the minimum / maximumburst pressure at a specified temperature.Recommended maximum temperaturefor a rupture disc with TEFLON seals is400°F (204°C). The recommendedmaximum temperature for a rupture discwith Polyethylene seals is 150°F (66°C).Polyethylene seals may be used forlower pressures at the discretion ofContinental Disc.

Continental'sComposite Rupture Discs are designedto provide instantaneous, full-openingpressure relief.Continental Disc offers twoComposite Type rupture disc designstyles, a preformed style, like the CDC orPLV Rupture Disc; and a flat style, likeC.D.C.'s ENVIRO-SEAL Rupture Disc.Preformed CompositeRupture DiscA Preformed Composite Rupture Discconsists of two or more components ofmetallic or non-metallic materials. Thesecomponents generally include a metallictop section, a metallic or nonmetallicseal member, and an optional vacuumsupport.Preformed CompositeRupture Disc Features:• Excellent performance in lowpressure applications• Operation to 80% of the rupturedisc's rated (marked) burst pressure• For use in gaseous or liquid service• Made from a variety of corrosionresistant materials• Non-fragmenting design when usedwith a non-metallic seal• Ideal for use under a safety reliefvalve to isolate the valve fromprocess media• Provided with Continental's uniqueThree-Dimensional Flow DirectionTag as a standardUnique Seven-HoleDesignContinental's Preformed CompositeRupture Discs also feature our seven-hole pattern, positioned at the apex ofthe rupture disc's top section. Thisunique configuration, in combination withthe pre-cut sections along the dome,provide non-fragmenting characteristicswhen used with a non-metallic orTEFLON®** seal. By using this seven-hole design, thicker, more durable mate-rials can be used to manufacture therupture disc while still achieving the high80% operating-to-burst-pressure ratio.Various seal material options, suchas TEFLONS and exotic metals, helpinsure excellent corrosion resistance.Continental's non-metallic seals areessential to minimize fragmentation.When ordering, please specify if yourapplication requires a non-fragmentingrupture disc.RecommendedOperating ConditionsContinental's Preformed CompositeRupture Discs can be used in a varietyof applications, including equipmentoperating at up to 80% of the rupturedisc's rated (stamped) burst pressureand systems having either liquid or gasprocesses.Under ideal operating conditions,such as static pressure and a tempera-ture well below the maximum recom-mended for the rupture disc materialused, Preformed Composite RuptureDiscs may be subjected to operatingpressures exceeding 80% of the rated(stamped) burst pressure. Contact thefactory for additional information aboutthe use of a Composite Rupture Discabove this 80% operating ratio.Sizes and MaterialsSizes ranging from 1" through 30"(25mm to 750mm) are available withburst pressures from 1.5 psig to 1440psig (0,10 barg to 100 barg).

Continental'sComposite Rupture Discs are designedto provide instantaneous, full-openingpressure relief.Continental Disc offers twoComposite Type rupture disc designstyles, a preformed style, like the CDC orPLV Rupture Disc; and a flat style, likeC.D.C.'s ENVIRO-SEAL Rupture Disc.Preformed CompositeRupture DiscA Preformed Composite Rupture Discconsists of two or more components ofmetallic or non-metallic materials. Thesecomponents generally include a metallictop section, a metallic or nonmetallicseal member, and an optional vacuumsupport.Preformed CompositeRupture Disc Features:• Excellent performance in lowpressure applications• Operation to 80% of the rupturedisc's rated (marked) burst pressure• For use in gaseous or liquid service• Made from a variety of corrosionresistant materials• Non-fragmenting design when usedwith a non-metallic seal• Ideal for use under a safety reliefvalve to isolate the valve fromprocess media• Provided with Continental's uniqueThree-Dimensional Flow DirectionTag as a standardUnique Seven-HoleDesignContinental's Preformed CompositeRupture Discs also feature our seven-hole pattern, positioned at the apex ofthe rupture disc's top section. Thisunique configuration, in combination withthe pre-cut sections along the dome,provide non-fragmenting characteristicswhen used with a non-metallic orTEFLON®** seal. By using this seven-hole design, thicker, more durable mate-rials can be used to manufacture therupture disc while still achieving the high80% operating-to-burst-pressure ratio.Various seal material options, suchas TEFLONS and exotic metals, helpinsure excellent corrosion resistance.Continental's non-metallic seals areessential to minimize fragmentation.When ordering, please specify if yourapplication requires a non-fragmentingrupture disc.RecommendedOperating ConditionsContinental's Preformed CompositeRupture Discs can be used in a varietyof applications, including equipmentoperating at up to 80% of the rupturedisc's rated (stamped) burst pressureand systems having either liquid or gasprocesses.Under ideal operating conditions,such as static pressure and a tempera-ture well below the maximum recom-mended for the rupture disc materialused, Preformed Composite RuptureDiscs may be subjected to operatingpressures exceeding 80% of the rated(stamped) burst pressure. Contact thefactory for additional information aboutthe use of a Composite Rupture Discabove this 80% operating ratio.Sizes and MaterialsSizes ranging from 1" through 30"(25mm to 750mm) are available withburst pressures from 1.5 psig to 1440psig (0,10 barg to 100 barg). Because ofthe availability of a variety of seal materi-als, these rupture discs can be used inservice temperatures of up to 1000°F(542°C) and can resist most corrosiveand atmospheric conditions. The metallictop section can be manufactured fromvarious materials to meet the needs ofeach individual application.** TEFLON is a registered trademark of E.I. du Pont de Nemours and Company used under license.2Table VI - 30° Insert Holder Weights and Dimensions16"400mmWEIGHTS AND DIMENSIONS1211NOTE: Consult factory for availability of flange classes or sizes not listed.ANSI DIN JIS Height WeightNominalSize Class Outside Dia.
