1.0 Introduction

1.1 TheViegaPropress™GSystem

For many years copper tubing has been used for gaspiping systems because of its excellent performance.Copper tubing is widely used for liquefied petroleum(LP) and natural gas (NG) piping systems. AustralianStandard AS5601, “Gas installations” permits coppertube toAS1432TypeAandB tobeused forpressureapplications up to 200kPa. Brazing (not soldering),flangesandcompressionjointshavebeenthetraditionalmethodsforjoiningcoppertubing.

With the Australian approval of copper Propress™Gfittings for gas piping systems, another viable joiningmethod is available for copper tubing. Propress™Gfittingswillallowforafaster,lowercost,joiningmethodforgaspiping.

Viega, the company that developed the Propress™Gsystem, has over 15 years of experience using pressconnectfittingsingaspipingsystems.TheViegafittingshavebeenapproved inEurope formanyyears forgaspipingsystem.Thelowercostinstallationhasresultedin extensive use of copper gas piping systems usingpressconnectfittings.

ViegaPropress™Gfittingsusedforgasinstallationsaresimilar to the Propress fittings used in water pipingsystems. There are two main differences betweenPropress™G(gas)fittingsandPropress(water)fittings.

The sealing element for the Propress™G fittings isyellowandismadeofHydrogenatedNitrileButadieneRubber (HNBR). Test results have shown that thissealing element can maintain a gas tight seal attemperaturesupto427°C.

The Propress™G fittings also incorporate the ViegapatentedSC(SmartConnect)feature.Thisfeaturewillallowairtoleakthroughthefittingduringtestingifthefittinghasnotbeenpressed.Whenthefittingispressed,theSCfeatureisclosedformingapermanentleakproofconnection.ViegaPropress™GfittingsalsohaveayellowdotandthewordGASprintedontheoutsideofthefittingtovisuallyindicatethatthefittingsareintendedforgassystems.Fittingsnothaving theyellowmarkingmustneverbeusedforgaspipingsystems.

1.2 ApprovalsandCertifications

1.4 ApplicationsPropress™Giswidelyusedforgasapplicationsduetoits excellent resistance to corrosion, and its ease ofhandlingandinstallation.Copperhasprovidedreliableserviceforseveraldecadesandofferseffectivesolutionstotoday’stechnologicalchallenges.

The Propress™G fittings are provided with a HNBRsealingelement,whichcanaccommodatetemperaturesof-40°Cto70°Candamaximumoperatingpressureof1000kPa,makingthemsuitableformanyapplications.ApplicationsforPropress™Gincludethefollowing:

• NaturalGas

• LPGas

• MixedGases

• FuelOil(forheatingapplications)

Note:ConsulttheCraneCopperTubeTechnicalSupportDepartment before installing the system in otherapplications,orapplicationswheretemperaturesand/orpressuresareoutsidethestatedratings.

2.0 ProductDescription

2.1 Propress™GFittingsPropress™GDN15toDN100fittingsaremanufactured inCopperandBronzewhichoffersoutstandingductility,durabilityandcorrosionresistance.Inadditiontotheseoutstanding material properties, the Propress™Gfittingsalsoofferthefollowingfeatures:

• UniqueSC‘SmartConnect’leakdetectionsystemwhichgreatlyimproveslinetestingprocedures.

• Press-fittinggeometrydesignedtoensurereliableconnections.

• Integralstopfordefinedinsertiondepth.

• Factory-fittedhigh-performanceHNBRsealingelement.

Thepressingprocessreshapesthefittingintheareaofthe sealing element ensuring continuous contactbetween the fitting, tubing, and the sealing element.Propress™G fittings are suitable for a wide variety ofresidentialandcommercialgaspipinginstallations.

For a detailed listing of available fittings, refer to theproductdatasheets,suppliedseparately.

2.2 HNBRSealingElementPropress™GpressfittingsaremanufacturedwithahighqualityHNBRsealingelement installedat thefactory.Thissealingelementisusedmainlyforapplicationsofnatural,propane,mixed,andmanufacturedgases,andcanbeusedinfueloilsystems.

Definition: HNBR – Hydrogenated Nitrile ButadieneRubber.Theseal isyellowincolourwithanoperatingtemperatureof-40°Cto70°C.HNBR iswidelyknownforitsphysicalstrengthandretentionofpropertiesafterlong-termexposuretoheat,oil,andchemicals.

TheuniquepropertiesattributedtoHNBRhaveresultedinwideadoptionofHNBRinautomotive,industrial,andassorted performance-demanding applications (e.g.engine seals, grommets, and gaskets); fuel systemsealsandhoses; transmissionsystem,bondedpistonseals;oilfieldpackers,androtaryshaftseals.Withitsexcellent performance for the most demanding ofapplicationsHNBRisthe idealchoiceforapplicationsneeding excellent physical properties, as well as oil,heat,and/orchemicalresistance.


The HNBR sealing element is not suitable for foodcontactapplicationsandcannotbeinstalledindrinkingwaterapplications.

2.3 CopperTubeAlthough Crane copper tube is the preferred tube,Propress™Gfittingsarewarrantedfor25yearsagainstleaks,faultymaterialsandmanufacturewheninstalledto specification on AS1432 complying copper tube.RefertoTables2.3.1and2.3.2.

Propress™G gas installations can be made withcorrosion resistant copper tube complying with therequirementsofAS1432TypeAandTypeB.TypeAandBcoppertube(AS1432),havebeenusedingassystemsfor many years. Usually, Type B is used for interiordistribution systems and Type A for any undergroundlines. The dimensions of copper tube used for gasinstallationsareshowninTable2.3.1and2.3.2.

The “Gas installations” Australian Standard AS5601permitstheuseofAS1432TypeAorTypeBcopperpipeforpressuresupto200kPainaboveandbelowgroundapplications. Where higher pressures apply, approvalmustbeobtainedfromtheTechnicalRegulator.Copperpiping is not permitted beneath a building at gaspressures exceeding 7kPa unless plastic coated or

coveredwithaproprietarywrappingacceptable to theTechnicalRegulator.

Under normal Australian conditions, Propress™G andcoppertubingcanalsobeinstalledoutsidewithoutanyadditional corrosion protection. However, wherepotential aggressive environments exist, precautionsshouldbetakentoprotecttheentirelengthofpiping.

In residential applications, copper tubing withPropress™G fittings can be used to run gas from themeterorsourcetofurnaces,boilers,gasranges,waterheaters, gas fireplaces, outdoor barbecues, anddecorativelighting.

Propress™G fittings are allowed to be installedunderground,butitisalwaysgoodpracticetoavoidthiswhenever possible. Copper tubing is available in longlengths and coils, reducing the number of fittingsrequired.

Copper piping should not be placed in direct contactwithmetalroofsduetothepotentialforcorrosionoftheroof material. In such cases, the copper should beraisedofftheroofwithsuitableclips.Also,intheeventthat piping may be exposed to large fluctuations intemperature, at the design stage, provision must bemade to accommodate the anticipated expansion andcontractionforcesthatwillbeimposedonthesystem.
