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 deemednecessary for the new construction1 of pressure vesselsthat will perform in a safe and reliable manner, andto interpret these rules when questions arise regardingtheir intent. With few exceptions, the rules do not, ofpractical necessity, reflect the likelihood and conse-quences of deterioration in service related to specificservice fluids or external operating environments. Rec-ognizing this, the Committee has approved a widevariety of construction1 rules in this Section to allowthe user or his designee to select those which willprovide a pressure vessel having a margin for deteriora-tion in service so as to give a reasonably long, safeperiod of usefulness. Accordingly, it is not intendedthat this Section be used as a design handbook; rather,engineering judgment must be employed in the selectionof those sets of Code rules suitable to any specificservice or need.

This Code contains mandatory requirements, specificprohibitions, and nonmandatory guidance for construc-tion1 activities. The Code does not address all aspectsof these activities and those aspects which are notspecifically addressed should not be considered prohib-ited. The Code is not a handbook and cannot replaceeducation, experience, and the use of engineering judg-ment. The phraseengineering judgmentrefers to techni-cal judgments made by knowledgeable designers experi-enced in the application of the Code. Engineeringjudgments must be consistent with Code philosophyand such judgments must never be used to overrulemandatory requirements or specific prohibitions ofthe 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-

1 Construction, as used in this Foreword, is an all-inclusive termcomprising materials, design, fabrication, examination, inspection,testing, certification, and pressure relief.

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 theyare 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-

viii

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.

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 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 is


limited 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 inSection 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 which may be used inCode construction. Material produced to an acceptable

ix

specification with requirements different from the re-quirements of the corresponding specifications listed inAppendix A of Part A or Part B may also be usedin 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 which 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 which is

xi

“rate,” or “endorse” any item, construction, or activityand there shall be no statements or implications whichmight 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 whichtend 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.

INTRODUCTION

SCOPE

U-1 SCOPE

U-1(a)U-1(a)(1) The Foreword provides the basis for the

rules described in this Division.U-1(a)(2) For the scope of this Division, pressure

vessels are containers for the containment of pressure,either internal or external. This pressure may be obtainedfrom an external source, or by the application of heatfrom a direct or indirect source, or any combinationthereof.

U-1(a)(3) This Division contains mandatory re-quirements, specific prohibitions, and nonmandatoryguidance for pressure vessel materials, design, fabrica-tion, examination, inspection, testing, certification, andpressure relief. The Code does not address all aspectsof these activities, and those aspects which are notspecifically addressed should not be considered prohib-ited. Engineering judgment must be consistent with thephilosophy of this Division, and such judgments mustnever be used to overrule mandatory requirements orspecific prohibitions of this Division. See also informa-tive and nonmandatory guidance regarding metallurgicalphenomena in Appendix 6 of Section II, Part D.

U-1(b)This Division is divided into three Subsections,Mandatory Appendices, and Nonmandatory Appendices.Subsection A consists of Part UG, covering the generalrequirements applicable to all pressure vessels. Subsec-tion B covers specific requirements that are applicableto the various methods used in the fabrication ofpressure vessels. It consists of Parts UW, UF, andUB dealing with welded, forged, and brazed methods,respectively. Subsection C covers specific requirementsapplicable to the several classes of materials used inpressure vessel construction. It consists of Parts UCS,UNF, UHA, UCI, UCL, UCD, UHT, ULW, and ULTdealing with carbon and low alloy steels, nonferrousmetals, high alloy steels, cast iron, clad and linedmaterial, cast ductile iron, ferritic steels with propertiesenhanced by heat treatment, layered construction, andlow temperature materials, respectively. Section II, PartD also contains tables of maximum allowable stressvalues for these classes of materials.

The Mandatory Appendices address specific subjectsnot covered elsewhere in this Division, and their require-ments are mandatory when the subject covered isincluded in construction under this Division. The Non-mandatory Appendices provide information and sug-gested good practices.

U-1(c)U-1(c)(1) The scope of this Division has been

established to identify the components and parametersconsidered in formulating the rules given in this Divi-sion. Laws or regulations issued by municipality, state,provincial, federal, or other enforcement or regulatorybodies having jurisdiction at the location of an installa-tion establish the mandatory applicability of the Coderules, in whole or in part, within their jurisdiction.Those laws or regulations may require the use of thisDivision of the Code for vessels or components notconsidered to be within its Scope. These laws orregulations should be reviewed to determine size orservice limitations of the coverage which may be differ-ent or more restrictive than those given here.

U-1(c)(2)Based on the Committee’s consideration,the following classes of vessels are not included inthe scope of this Division; however, any pressure vesselwhich meets all the applicable requirements of thisDivision may be stamped with the Code U Symbol:

(a) those within the scope of other Sections;(b) fired process tubular heaters;(c) pressure containers which are integral parts

or components of rotating or reciprocating mechanicaldevices, such as pumps, compressors, turbines, genera-tors, engines, and hydraulic or pneumatic cylinderswhere the primary design considerations and/or stressesare derived from the functional requirements of thedevice;

(d) except as covered in U-1(f), structures whoseprimary function is the transport of fluids from onelocation to another within a system of which it is anintegral part, that is, piping systems;

(e) piping components, such as pipe, flanges,bolting, gaskets, valves, expansion joints, fittings, andthe pressure containing parts of other components, suchas strainers and devices which serve such purposes asmixing, separating, snubbing, distributing, and metering

(f) a vessel for containing water1 under pressure,including those containing air the compression of whichserves only as a cushion, when none of the followinglimitations are exceeded:

(1) a design pressure of 300 psi (2070 kPa);(2) a design temperature of 210°F (99°C);

(g) a hot water supply storage tank heated bysteam or any other indirect means when none of thefollowing limitations is exceeded:

(1) a heat input of 200,000 Btu/hr (58.6 kW);(2) a water temperature of 210°F (99°C);(3) a nominal water containing capacity of

(j) pressure vessels for human occupancy.2

U-1(d) The rules of this Division have been formu-lated on the basis of design principles and constructionpractices applicable to vessels designed for pressuresnot exceeding 3000 psi (20685 kPa). For pressuresabove 3000 psi (20685 kPa), deviations from andadditions to these rules usually are necessary to meetthe requirements of design principles and constructionpractices for these higher pressures. Only in the eventthat after having applied these additional design princi-ples and construction practices the vessel still complieswith all of the requirements of this Division may itbe stamped with the applicable Code symbol.

U-1(e) In relation to the geometry of pressure con-taining parts, the scope of this Division shall includethe following:

U-1(e)(1) where external piping; other pressurevessels including heat exchangers; or mechanical de-vices, such as pumps, mixers, or compressors, are tobe connected to the vessel:

(a) the welding end connection for the firstcircumferential joint for welded connections [see UW-13(g)];

1 The water may contain additives provided the flash point of theaqueous solution at atmospheric pressure is 185°F or higher. Theflash point shall be determined by the methods specified in ASTMD 93 or in ASTM D 56, whichever is appropriate.2 Requirements for pressure vessels for human occupancy are coveredby ANSI /ASME PVHO-1.

(b) the first threaded joint for screwed connec-tions;

(c) the face of the first flange for bolted, flangedconnections;

(d) the first sealing surface for proprietary con-nections or fittings;

GENERAL

U-2 GENERAL

(a) The user or his designated agent4 shall establishthe design requirements for pressure vessels, takinginto consideration factors associated with normal opera-tion, such other conditions as startup and shutdown,and abnormal conditions which may become a governingdesign consideration (see UG-22).

Such consideration shall include but shall not belimited to the following:

(1) the need for corrosion allowances;(2) the definition of lethal services. For example,

see UW-2(a).(3) the need for postweld heat treatment beyond

the requirements of this Division and dependent onservice conditions;

4 For this Division, the user’s designated agent may be either adesign agency specifically engaged by the user, the Manufacturer ofa system for a specific service which includes a pressure vessel asa part and which is purchased by the user, or an organization whichoffers pressure vessels for sale or lease for specific services.

3

(4) for pressure vessels in which steam is gener-ated, or water is heated [see U-1(g) and (h)], the needfor piping, valves, instruments, and fittings to performthe functions covered by PG-59 through PG-61 ofSection I.

(b) Responsibilities5

(1) The Manufacturer of any vessel or part to bemarked with the Code Symbol has the responsibilityof complying with all of the applicable requirementsof this Division and, through proper certification, ofassuring that all work done by others also complies.The vessel or part Manufacturer shall have availablefor the Inspector’s review the applicable design calcula-tions. See 10-5 and 10-15(d).

(2) Some types of work, such as forming, nonde-structive examination, and heat treating, may be per-formed by others (for welding, see UW-26 and UW-31). It is the vessel or part Manufacturer’s responsibilityto ensure that all work so performed complies withall the applicable requirements of this Division. Afterensuring Code compliance, the vessel or part may beCode stamped by the appropriate Code stamp holderafter acceptance by the Inspector.

(c) A vessel may be designed and constructed usingany combination of the methods of fabrication and theclasses of materials covered by this Division providedthe rules applying to each method and material arecomplied with and the vessel is marked as requiredby UG-116.

(d) When the strength of any part cannot be computedwith a satisfactory assurance of safety, the rules provideprocedures for establishing its maximum allowableworking pressure.

(e) It is the duty of the Inspector to make all ofthe inspections specified by the rules of this Division,and of monitoring the quality control and the examina-tions made by the Manufacturer. He shall make suchother inspections as in his judgment are necessary topermit him to certify that the vessel has been designedand constructed in accordance with the requirements.The Inspector has the duty of verifying that the applica-ble calculations have been made and are on file atManufacturer’s plant at the time the Data Report issigned. Any questions concerning the calculations raisedby the Inspector must be resolved. See UG-90(c)(1).

(f) The rules of this Division shall serve as the basisfor the Inspector to:

(1) perform the required duties;(2) authorize the application of the Code Symbol;

(3) sign the Certificate of Shop (or Field Assembly)Inspection.

(g) This Division of Section VIII does not containrules to cover all details of design and construction.Where complete details are not given, it is intendedthat the Manufacturer, subject to the acceptance of theInspector, shall provide details of design and construc-tion which will be as safe as those provided by therules of this Division.

(h) Field assembly of vessels constructed to thisDivision may be performed as follows.

(1) The Manufacturer of the vessel completes thevessel in the field, completes the Form U-1 or U-1AManufacturer’s Data Report, and stamps the vessel.

(2) The Manufacturer of parts of a vessel to becompleted in the field by some other party stampsthese parts in accordance with Code rules and suppliesthe Form U-2 or U-2A Manufacturer’s Partial DataReport to the other party. The other party, who musthold a valid U Certificate of Authorization, makesthe final assembly, required NDE, final pressure test;completes the Form U-1 or U-1A Manufacturer’s DataReport; and stamps the vessel.

(3) The field portion of the work is completed bya holder of a valid U Certificate of Authorizationother than the vessel Manufacturer. The stamp holderperforming the field work is required to supply aForm U-2 or U-2A Manufacturer’s Partial Data Reportcovering the portion of the work completed by hisorganization (including data on the pressure test if

conducted by the stamp holder performing the fieldwork) to the Manufacturer responsible for the Codevessel. The vessel Manufacturer applies his U Stampin the presence of a representative from his InspectionAgency and completes the Form U-1 or U-1A Manufac-turer’s Data Report with his Inspector.

In all three alternatives, the party completing andsigning the Form U-1 or U-1A Manufacturer’s DataReport assumes full Code responsibility for the vessel.In all three cases, each Manufacturer’s Quality ControlSystem shall describe the controls to assure compliancefor each Code stamp holder.

(i) For some design analyses, both a chart or curveand a formula or tabular data are given. Use of theformula or tabular data may result in answers whichare slightly different from the values obtained fromthe chart or curve. However, the difference, if any, iswithin practical accuracy and either method is ac-ceptable.
