ALLOWABLE STRESSForthemostpart,ASMEBPVCallowablestressesaredeterminedbyfourthings:tensilestrength,yieldstrength,time-dependentpropertiesathighertemperatures(creep),andproductform(bolting,weldedpipe,etc.).

Avoid Mishaps with Proper Material Selection

Material Strength & Joint Efficiency
TheJointEfficiencyisdeterminedfromthequalityofthejointdesignandthedegreeofexamination.Doubleweldedbuttjointsareconsideredthehighestqualityjointsandfullradiographyis,ofcourse,thehighestdegreeofexamination.Lowerqualityjointsandlowerexaminationwillbothresultinlowerjointefficiency.JointefficiencyisseenthroughoutthedesignformulasintheASMESectionVIII,Divisions1and2.Itisbasicallyamultiplieronthematerialallowablestress,thoughsometimesit’susedoesnotmakethatclear(see4.3.10inSectionVIII,Division2forexample).

ASME STAMP REQUIRES COMPLIANCE FOR DESIGN, MANUFACTURING & INSTALLATION
AUTHROIZED INSPECTION DESIGN & MANUFACTURINGAfundamentalprincipleisthattheASMEStampedpressurevesselmustreceiveaninspectionbyanauthorized“thirdparty”duringallstagestoverifycompliancewiththeapplicablerequirementsoftheCode.
Asignaturebyanauthorizedthirdparty,certifyingthattheobjecthasbeenmanufacturedinaccordancewiththerequirementsthereof,isakeystepfortheacceptanceofboilersandpressurevessels,especiallybyseveralbodiesinvolvedinthelegalizationprocess.
AUTHROIZED INSPECTION OF INSTALLATIONBesidesinspectingpressurevesselsinthestagesmentionedabove,aninspectorrepresentingthejurisdictionofinstallationmayneedtoapprovetheinstallation..Aftertheequipmenthasbeenplacedintoservice,anauthorizedinspectororarepresentativeofthejurisdictioncanperiodicallyinspectthecompliancewithlegalrequirementsdefinedbylocalregulationsonboilersandpressurevessels.
ASME STAMPEDInadditiontoalltherequirements,anystampedboilerorpressurevesselmustcomplywithallaspectsoftheCode,meaningitmustbedesigned,fabricated,andexaminedbyamanufacturerholdinganAuthorizationCertificateissuedbyASME.
NON-ASME STAMPEDEvenwhenapressurevesselisdesignedpertheASMECode,theequipment,itself,maynotbeASMEstamped.EquipmentthathastheASMEstampisusuallyassociatedwithaqualitylevel,and,therefore,safety.
ASMEstampedequipmentrequiresthoroughdocumentationmanagementandstringentinspectionprocedures.Thestampandassociatedprocessesaregenerallytherequirementsofthecustomerandthejurisdictionofinstallation,toensuresafetyandreduceliability.
