  18. 18. h e 1,January 1999 BS 6500 :1997ForewordThis British Standardhas been prepared byTechnical CommitteewE/1. It is a newedition of the 1994version and incorporatesall technical changesup to and includingAmendment No.4 (September 1996) associatedwith that version.This editionhas been published, for the firsttime, using an electronic processwhichhas made it necessaryto amend certainaspects of the table andfigure numbering.The table and figure numbers are now derived from the number of the main clause inwhich they are cited, not from subclauseor sub-subclause numbers.This will reducethe opportunity forerror in future updating.Despite the various amendmentsW have been made to thisstandard sinceit wasíïrst published in 1976,some of the requirementscan still be traced backto theproposals in ISO/DIS 2694Pressurevessels drafted by Technid Committee11 of theInternationalOqdmtion for StandardizationUSO) which were takeninto account inpreparing theoriginal edition.BS 5500,which covers pressure vessels manufactured from carbon, ferritic alloy,I austenitic steels,aluminium and nickel replaced the followingstandardsFusion welded pressure W& for genemlpurposesPart 3AluminiumFusion welded pressure W& for use in W chemical,petroleum anddied industries1515 part 1 Cadon and f-tk au~ysteelsPart 2 Austenitic stainless steelBS 1500 Part 1 Carbonand low auOy steelsPrevious editionshave stated the intention of integrating into one BritishStandardthe requirementsfor design, manufactwe, testing and inspectionof fusion weldedpressure vessels. It is intended to keep under review the question of publishingappropriate supplements coveringother types of pressurevessels.If there is sufficient demand from industry,the standard will be extended to coverI other non-ferrous materials.The requirementsof thisstandard vary considerably depending upon thethicknessand type of material to be used. Whenthiscombination is such as will permîtsatisfactmy fabrication by relatively straightforward processes, spotnondestructivetesting is permitted without any penaltyin design thickness;in certain cases visualinspection only is permitted with an appropriate penalty on design thickness.The strengthsthat may be assumed for design purposesof materials coveredbyI current British Standards,as well as some materialsto withdrawn standards whichI are still available,are individually specified (see table2.3-1).Design stxengths inthe creep range are given fora range of design lifetimesthat maybe extended,on expiry, on the basis of periodic ‘fitnessforcontinued-servicereviews’based on inspectionand consideration of actualload-temperaturehistmy. Thisapproach recognizes the limitations inherent in any simple design method for vesselsoperatingin the creep range andalso provides a flexible basis that may beused incases where the design strength values which have been derived fromIS0data, aresigruficantly different fromthose used with successin the past. Specific requirementsfor these reviews are not given in thisstandard.Recommendations coveringaspects requiring further considerationin particular casesare given in the annexes. The BritishStandards Institutionwillbe pleasedto receiveconstructive proposals based on experience or researchthatmay leadtoimprovementsin these annexes.O BSI 1998Copyright British Standards InstitutionProvided by IHS under license with BSI - Uncontrolled Copy Licensee=BP International/5928366101Not for Resale, 03/22/2009 19:40:28 MDTNo reproduction or networking permitted without license from IHS--`,``,````,```,``,`,`,,`,,``,,`-`-`,,`,,`,`,,`---
  19. 19. BS 5500 :1997 Issue 2, November 1999Reference is made in the text to a number of standards which have been withdrawn.Such standards are identifiedin the list of references (see page III). Considerationiscurrently being givento whether replacement standardsare available orare beingdeveloped, for example, inthe European programme andto the implications forBS 5500 of such replacement standards. When a decision is made about anyreplacementstandards, these will be identifed by the issueof an amendment.As with the previous editions,it is intended to keep thisstandard up to date by theissue from timeto time of replacement pages, or additional pageswhere necessary.Each replacement oradded pagewillcarry an issue number (with the effective date)indicating its relationshipto the original standard,the pages of which are markedIssue 1.For exampleIssue 1willindicatean originalpage or one thathas been added to the on@standard andhas not been amended since insertion;Issue2 will indicate a firstamendment of either an original page oran added page;Issue3 willindicate a second amendment of either anoriginal page or an addedPage.Sidelining on replacementpages will indicate that changes of technical or referencesignificance have been madeat thatpoint.It should be notedthatthe effective date of amendments to thisedition will usuallybe later than the publicationdate to allow users time to amend theirown workingproceduresand documentation.The issue date on each page reflects the effectivedate not the publication date.The following m e s are reproduced by courtesy of the AmericanWeldmg Researchcouncil.FigureG.32 was originauypublished as figure 2 on page21 of WRC Bulletin90September1963FigureG.33 was originallypublished as figure 3 on page 21of WRC Bulletin90September1963Figure G.34 was originally published as figure 7 on page 24 ofWRC Bulletin90September1963FlgureG.35was originally published as figure 8 on page 24of WRC Bulletin90September1963Figure G.36 was originauypublished as figure9 on page 25 of WRC Bulletin90September1963FigureG.37 was originally published as figure 10 onpage 25 of WRC Bulletin90September1963Figure G.38was originally published as figure 11on page 26 of WRC Bulletin90September1963Figure G.39 was ongmdly published as figure 12on page 26 of W C Bulletin90September1963Figures G.40 to G.47 are reproduced by courtesyof the Intemational JoumaE ofSolids and Structures, 1967.This standard may be referred to by the UK Health and Safety Executive (HSE)when giving guidance.I A British Standaxd does not purport to include all the necessary provisionsof aI conmt Usersof British Standardsare responsible fortheir correct application.Compliance with a British Standard does not of itselfconfer immunityfrom legal obligations.xviii O BSI 091999Copyright British Standards InstitutionProvided by IHS under license with BSI - Uncontrolled Copy Licensee=BP International/5928366101Not for Resale, 03/22/2009 19:40:28 MDTNo reproduction or networking permitted without license from IHS--`,``,````,```,``,`,`,,`,,``,,`-`-`,,`,,`,`,,`---

Theintent of this requirementis regarded as satisfiedwhere inspectionis canied out by competentpersonnel of a separate engineering inspectiondepartment maintained bythe purchaser of the vessel.An inspection department maintainedby themanufacturer does not &@ this requirement except:a) thatspecific responsibilitiesmay be delegatedatthe discretion ofthe Inspecting Authority or-on; orb) in the case of vessels for the manufacturers ownuse and not for resale.This standard applies onlyto vessels made bymanufacturers whocan satisfy the Inspecting Authorityor Organizationthat they are competent and suitablyequippedto fulfilthe appropriate requirementsof thisstandard.The requirements for testing and inspecting seriallymanufactured pressure vesselsare given in annexV Inall other respectsthe appropriate requirementsin thespecification applyGlass lined steel vessels require special designconsiderations subjectto the limitsimposed by themethod of construction which should have theagreement of the Inspecting Authority.1.1.4 This standard does not cover the following.a) Storage tanks designed for the storage of liquidsat near atmospheric pressures, i.e.where thepressure additionalto that due to the hydrostatichead does not exceed140mbar) above or 6mbarbelow atmospheric pressure in accordancewithsuch standads as BS 799, BS 2594, BS 2654, BS 7777.b) Low pressure, aboveground storagetanks whichhave a single verticalaxis of revolution designed forthe storageof li uids at a pressure notexceeding1bar18.c) Vessels in which thestresses calculated inaccordance with theequations given in section3 areless than 10% of the designstresspermitted bysection 3.d)Multilayered, autofrettaged, prestressed vessels or Iother special designsof vessels which may beappropriate for veryhigh pressures.e) lkansportvessels, i.e.vessels used for transport ofcontents under presswe.f) Vessels for specificapplicationswhich are coveredby standardslistedin the BSI Catalogue.NOTE. The titles of the publicationsreferred to in this standardare listed on the last page.1.1.6 This standard does not addressthe nature orconsequences of a firein the vicinity of a pressurevessel.
