FOREWORD
The American Society of Mechanical Engineers setup a committee in 1911 for the purpose of formulatingstandard rules for the construction of steam boilers andother pressure vessels. This committee is now calledthe Boiler and Pressure Vessel Committee.
The Committee’s function is to establish rules ofsafety governing the design, fabrication, and inspectionduring construction of boilers and pressure vessels, andto interpret these rules when questions arise regardingtheir intent. In formulating the rules, the Committeeconsiders the needs of users, manufacturers, and inspec-tors of pressure vessels. The objective of the rules isto afford reasonably certain protection of life andproperty and to provide a margin for deterioration inservice so as to give a reasonably long, safe periodof usefulness. Advancements in design and materialand the evidence of experience have been recognized.
This Code contains mandatory requirements, specificprohibitions, and nonmandatory guidance for construc-tion1 activities. The Code does not address all aspects ofthese activities and those aspects that are not specificallyaddressed should not be considered prohibited. TheCode is not a handbook and cannot replace education,experience, and the use of engineering judgment. Thephraseengineering judgmentrefers to technical judg-ments made by knowledgeable designers experiencedin the application of the Code. Engineering judgmentsmust be consistent with Code philosophy and suchjudgments must never be used to overrule mandatoryrequirements or specific prohibitions of the Code.
The Committee recognizes that tools and techniquesused for design and analysis change as technologyprogresses and expects engineers to use good judgmentin the application of these tools. The designer is respon-sible for complying with Code rules and demonstratingcompliance with Code equations when such equationsare mandatory. The Code neither requires nor prohibitsthe use of computers for the design or analysis ofcomponents constructed to the requirements of theCode. However, designers and engineers using computerprograms for design or analysis are cautioned that they
1 Construction, as used in this Foreword, is an all-inclusive termcomprising materials, design, fabrication, examination, inspection,testing, certification, and pressure relief.
vii
are responsible for all technical assumptions inherentin the programs they use and they are responsible forthe application of these programs to their design.
The Code does not fully address tolerances. Whendimensions, sizes, or other parameters are not specifiedwith tolerances, the values of these parameters areconsidered nominal and allowable tolerances or localvariances may be considered acceptable when basedon engineering judgment and standard practices asdetermined by the designer.
The Boiler and Pressure Vessel Committee dealswith the care and inspection of boilers and pressurevessels in service only to the extent of providingsuggested rules of good practice as an aid to ownersand their inspectors.
The rules established by the Committee are not tobe interpreted as approving, recommending, or endors-ing any proprietary or specific design or as limitingin any way the manufacturer’s freedom to choose anymethod of design or any form of construction thatconforms to the Code rules.
The Boiler and Pressure Vessel Committee meetsregularly to consider revisions of the rules, new rulesas dictated by technological development, Code Cases,and requests for interpretations. Only the Boiler andPressure Vessel Committee has the authority to provideofficial interpretations of this Code. Requests for revi-sions, new rules, Code Cases, or interpretations shallbe addressed to the Secretary in writing and shall givefull particulars in order to receive consideration andaction (see Mandatory Appendix covering preparationof technical inquiries). Proposed revisions to the Coderesulting from inquiries will be presented to the MainCommittee for appropriate action. The action of theMain Committee becomes effective only after confirma-tion by letter ballot of the Committee and approval byASME.
Proposed revisions to the Code approved by theCommittee are submitted to the American NationalStandards Institute and published inMechanical Engi-neeringto invite comments from all interested persons.After the allotted time for public review and finalapproval by ASME, revisions are published annuallyin Addenda to the Code.
Code Cases may be used in the construction ofcomponents to be stamped with the ASME Code symbolbeginning with the date of their approval by ASME.
After Code revisions are approved by ASME, theymay be used beginning with the date of issuance shownon the Addenda. Revisions, except for revisions tomaterial specifications in Section II, Parts A and B,become mandatory 6 months after such date of issuance,except for boilers or pressure vessels contracted forprior to the end of the 6 month period. Revisions tomaterial specifications are originated by the AmericanSociety for Testing and Materials (ASTM), and otherrecognized national or international organizations andare usually adopted by ASME. However, those revisionsmay or may not have any effect on the suitability ofmaterial, produced to earlier editions of specifications,for use in ASME construction. ASME material specifi-cations approved for use in each construction Code arelisted in the Appendices of Section II, Parts A and B.These Appendices list, for each specification, the latestedition adopted by ASME, and earlier and later editionsconsidered by ASME to be identical for ASME con-struction.
Manufacturers and users of components are cautionedagainst making use of revisions and Cases that are lessrestrictive than former requirements without havingassurance that they have been accepted by the properauthorities in the jurisdiction where the component isto be installed.
Each state and municipality in the United States andeach province in Canada that adopts or accepts one ormore Sections of the Boiler and Pressure Vessel Codeis invited to appoint a representative to act on theConference Committee to the Boiler and Pressure VesselCommittee. Since the members of the Conference Com-mittee are in active contact with the administration andenforcement of the rules, the requirements for inspectionin this Code correspond with those in effect in theirrespective jurisdictions. The required qualifications foran Authorized Inspector under these rules may beobtained from the administrative authority of any state,municipality, or province which has adopted these rules.
The Boiler and Pressure Vessel Committee in theformulation of its rules and in the establishment ofmaximum design and operating pressures considersmaterials, construction, methods of fabrication, inspec-tion, and safety devices. Permission may be grantedto regulatory bodies and organizations publishing safetystandards to use a complete Section of the Code byreference. If usage of a Section, such as Section IX,involves exceptions, omissions, or changes in provisions,the intent of the Code might not be attained.
viii
Where a state or other regulatory body, in the printingof any Section of the Boiler and Pressure Vessel Code,makes additions or omissions, it is recommended thatsuch changes be clearly indicated.
The National Board of Boiler and Pressure VesselInspectors is composed of chief inspectors of statesand municipalities in the United States and of provincesin Canada that have adopted the Boiler and PressureVessel Code. This Board, since its organization in 1919,has functioned to uniformly administer and enforce therules of the Boiler and Pressure Vessel Code. Thecooperation of that organization with the Boiler andPressure Vessel Committee has been extremely helpful.
The Code Committee does not rule on whether acomponent shall or shall not be constructed to theprovisions of the Code. The Scope of each Sectionhas been established to identify the components andparameters considered by the Committee in formulatingthe Code rules. Laws or regulations issued by municipal-ity, state, provincial, federal, or other enforcement orregulatory bodies having jurisdiction at the location ofan installation establish the mandatory applicability ofthe Code rules, in whole or in part, within theirjurisdiction. Those laws or regulations may require theuse of this Code for vessels or components not consid-ered to be within its Scope or may establish additions ordeletions in that Scope. Accordingly, inquiries regardingsuch laws or regulations are to be directed to theissuing enforcement or regulatory body.
Questions or issues regarding compliance of a specificcomponent with the Code rules are to be directed tothe ASME Certificate Holder (Manufacturer). Inquiriesconcerning the interpretation of the Code are to bedirected to the ASME Boiler and Pressure VesselCommittee. ASME is to be notified should questionsarise concerning improper use of an ASME Codesymbol.
The specifications for materials given in Section IIare identical with or similar to those of the Specificationspublished by ASTM, AWS, and other recognized na-tional or international organizations. When reference ismade in an ASME material specification to a non-ASME specification for which a companion ASMEspecification exists, the reference shall be interpretedas applying to the ASME material specification. Notall materials included in the material specifications inSection II have been adopted for Code use. Usage islimited to those materials and grades adopted by atleast one of the other Sections of the Code for applica-tion under rules of that Section. All materials allowedby these various Sections and used for constructionwithin the scope of their rules shall be furnished inaccordance with material specifications contained in
Section II or referenced in Appendices A of SectionII, Parts A and B except where otherwise provided inCode Cases or in the applicable Section of the Code.Materials covered by these specifications are acceptablefor use in items covered by the Code Sections onlyto the degree indicated in the applicable Section. Materi-als for Code use should preferably be ordered, produced,and documented on this basis; Appendix A to SectionII, Part A and Appendix A to Section II, Part B listeditions of ASME and year dates of specifications thatmeet ASME requirements and that may be used inCode construction. Material produced to an acceptablespecification with requirements different from the re-quirements of the corresponding specifications listed inAppendix A of Part A or Part B may also be used
ix
in accordance with the above, provided the materialmanufacturer or vessel manufacturer certifies with evi-dence acceptable to the Authorized Inspector that thecorresponding requirements of specifications listed inAppendix A of Part A or Part B have been met.Material produced to an acceptable material specificationis not limited as to country of origin.
When required by context in this Section, the singularshall be interpreted as the plural, and vice-versa; andthe feminine, masculine, or neuter gender shall betreated as such other gender as appropriate.
Publication of the SI (Metric) Edition of the ASMEBoiler and Pressure Vessel Code was discontinued withthe 1986 Edition. Effective October 1, 1986, the SIEdition was withdrawn as an ASME Boiler and PressureVessel Code document.
STATEMENT OF POLICYON THE USE OF CODE SYMBOLS AND
CODE AUTHORIZATION IN ADVERTISING
ASME has established procedures to authorize quali-fied organizations to perform various activities in ac-cordance with the requirements of the ASME Boilerand Pressure Vessel Code. It is the aim of the Societyto provide recognition of organizations so authorized.An organization holding authorization to perform vari-ous activities in accordance with the requirements ofthe Code may state this capability in its advertisingliterature.
Organizations that are authorized to use Code Symbolsfor marking items or constructions that have been con-structed and inspected in compliance with the ASMEBoiler and Pressure Vessel Code are issued Certificates ofAuthorization. It is the aim of the Society to maintain thestanding of the Code Symbols for the benefit of the users,the enforcement jurisdictions, and the holders of the sym-bols who comply with all requirements.
Based on these objectives, the following policy hasbeen established on the usage in advertising of facsimilesof the symbols, Certificates of Authorization, and refer-ence to Code construction. The American Society ofMechanical Engineers does not “approve,” “certify,”
STATEMENT OF POLICYON THE USE OF ASME MARKING
TO IDENTIFY MANUFACTURED ITEMS
The ASME Boiler and Pressure Vessel Code providesrules for the construction of boilers, pressure vessels, andnuclear components. This includes requirements for mate-rials, design, fabrication, examination, inspection, andstamping. Items constructed in accordance with all of theapplicable rules of the Code are identified with the officialCode Symbol Stamp described in the governing Section ofthe Code.
Markings such as “ASME,” “ASME Standard,” orany other marking including “ASME” or the variousCode Symbols shall not be used on any item that is
xi
“rate,” or “endorse” any item, construction, or activityand there shall be no statements or implications thatmight so indicate. An organization holding a CodeSymbol and/or a Certificate of Authorization may statein advertising literature that items, constructions, oractivities “are built (produced or performed) or activitiesconducted in accordance with the requirements of theASME Boiler and Pressure Vessel Code,” or “meetthe requirements of the ASME Boiler and PressureVessel Code.”
The ASME Symbol shall be used only for stampingand nameplates as specifically provided in the Code.However, facsimiles may be used for the purpose offostering the use of such construction. Such usage maybe by an association or a society, or by a holder of a CodeSymbol who may also use the facsimile in advertising toshow that clearly specified items will carry the symbol.General usage is permitted only when all of a manufactur-er’s items are constructed under the rules.
The ASME logo, which is the cloverleaf with theletters ASME within, shall not be used by any organiza-tion other than ASME.
not constructed in accordance with all of the applicablerequirements of the Code.
Items shall not be described on ASME Data ReportForms nor on similar forms referring to ASME thattend to imply that all Code requirements have beenmet when, in fact, they have not been. Data ReportForms covering items not fully complying with ASMErequirements should not refer to ASME or they shouldclearly identify all exceptions to the ASME require-ments.

The Code does not contain rules to cover all details of designand construction. Where complete details are not given, it isintended that the manufacturer, subject to the acceptance ofthe Authorized Inspector, shall provide details of design andconstruction which will be as safe as otherwise provided bythe rules in the Code.
The scope of jurisdiction of Section I applies to the boilerproper and to the boiler external piping.
Superheaters, economizers, and other pressure parts con-nected directly to the boiler without intervening valves shall beconsidered as parts of the boiler proper, and their constructionshall conform to Section I rules.
Boiler external piping shall be considered as that piping whichbegins where the boiler proper or separately fired superheaterterminates at:
(a) the first circumferential joint for welding end connec-tions; or
(b) the face of the first flange in bolted flanged connec-tions; or
(c) the first threaded joint in that type of connection; andwhich extends up to and including the valve or valves requiredby this Code.
ASME Code Certification (including Data Forms and CodeSymbol Stamping), and/or inspection by the Authorized Inspec-tor, when required by this Code, is required for the boiler properand the boiler external piping.
1 Power boiler — a boiler in which steam or other vapor is generatedat a pressure of more than 15 psi for use external to itself.2 Electric boiler — a power boiler or a high-temperature water boilerin which the source of heat is electricity.3 Miniature boiler — a power boiler or a high-temperature waterboiler in which the limits specified in PMB-2 are not exceeded.4 High-temperature water boiler — a water boiler intended for opera-tion at pressures in excess of 160 psi and/or temperatures in excessof 250°F.
xxiii
Construction rules for materials, design, fabrication, installa-tion, and testing of the boiler external piping are contained inASME B31.1, Power Piping. Piping beyond the valve or valvesrequired by Section I is not within the scope of Section I, andit is not the intent that the Code Symbol Stamp be applied tosuch piping or any other piping.
The material for forced-circulation boilers, boilers with nofixed steam and water line, and high-temperature water boilersshall conform to the requirements of the Code. All other require-ments shall also be met except where they relate to specialfeatures of construction made necessary in boilers of these types,and to accessories that are manifestly not needed or used inconnection with such boilers, such as water gages and watercolumns.
Reheaters receiving steam which has passed through partof a turbine or other prime mover and separately fired steamsuperheaters which are not integral with the boiler are consid-ered fired pressure vessels and their construction shall complywith Code requirements for superheaters, including safety de-vices. Piping between the reheater connections and the turbineor other prime mover is not within the scope of the Code.
A pressure vessel in which steam is generated by the applica-tion of heat resulting from the combustion of fuel (solid, liquid,or gaseous) shall be classed as a fired steam boiler.
Unfired pressure vessels in which steam is generated shall beclassed as unfired steam boilers with the following exceptions:
(a) vessels known as evaporators or heat exchangers;(b) vessels in which steam is generated by the use of heat
resulting from operation of a processing system containing anumber of pressure vessels such as used in the manufacture ofchemical and petroleum products.
Unfired steam boilers shall be constructed under the provi-sions of Section I or Section VIII.
Expansion tanks required in connection with high-tempera-ture water boilers shall be constructed to the requirements ofSection I or Section VIII.
A pressure vessel in which an organic fluid is vaporized bythe application of heat resulting from the combustion of fuel(solid, liquid, or gaseous) shall be constructed under the provi-sions of Section I. Vessels in which vapor is generated incidentalto the operation of a processing system, containing a numberof pressure vessels such as used in chemical and petroleummanufacture, are not covered by the rules of Section I.
