FOREWORD

The American Society of Mechanical Engineers set up acommittee in 1911 for the purpose of formulating standardrules for the construction of steam boilers and other pres-sure vessels. This committee is now called the Boiler andPressure Vessel Committee.

The Committees function is to establish rules of safety,relating only to pressure integrity, governing the construc-tion1 of boilers, pressure vessels, transport tanks andnuclear components, and inservice inspection for pressureintegrity of nuclear components and transport tanks, andto interpret these rules when questions arise regarding theirintent. This code does not address other safety issues relat-ing to the construction of boilers, pressure vessels, transporttanks and nuclear components, and the inservice inspectionof nuclear components and transport tanks. The user ofthe Code should refer to other pertinent codes, standards,laws, regulations, or other relevant documents. With fewexceptions, the rules do not, of practical necessity, reflectthe likelihood and consequences of deterioration in servicerelated to specific service fluids or external operating envi-ronments. Recognizing this, the Committee has approveda wide variety of construction rules in this Section to allowthe user or his designee to select those which will providea pressure vessel having a margin for deterioration in ser-vice so as to give a reasonably long, safe period of use-fulness. Accordingly, it is not intended that this Sectionbe used as a design handbook; rather, engineering judgmentmust be employed in the selection of those sets of Coderules suitable to any specific service or need.

This Code contains mandatory requirements, specificprohibitions, and nonmandatory guidance for constructionactivities. The Code does not address all aspects of theseactivities and those aspects which are not specificallyaddressed should not be considered prohibited. The Codeis not a handbook and cannot replace education, experi-ence, and the use of engineering judgment. The phraseengineering judgment refers to technical judgments madeby knowledgeable designers experienced in the applicationof the Code. Engineering judgments must be consistent

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

with Code philosophy and such judgments must neverbe used to overrule mandatory requirements or specificprohibitions of the Code.

The Committee recognizes that tools and techniquesused for design and analysis change as technology prog-resses and expects engineers to use good judgment in theapplication of these tools. The designer is responsible forcomplying with Code rules and demonstrating compliancewith Code equations when such equations are mandatory.The Code neither requires nor prohibits the use of comput-ers for the design or analysis of components constructedto the requirements of the Code. However, designers andengineers using computer programs for design or analysisare cautioned that they are responsible for all technicalassumptions inherent in the programs they use and theyare responsible for the application of these programs totheir design.

The Code does not fully address tolerances. Whendimensions, sizes, or other parameters are not specifiedwith tolerances, the values of these parameters are consid-ered nominal and allowable tolerances or local variancesmay be considered acceptable when based on engineeringjudgment and standard practices as determined by thedesigner.

The Boiler and Pressure Vessel Committee deals withthe care and inspection of boilers and pressure vessels inservice only to the extent of providing suggested rules ofgood practice as an aid to owners and their inspectors.

The rules established by the Committee are not to beinterpreted as approving, recommending, or endorsing anyproprietary or specific design or as limiting in any way themanufacturers freedom to choose any method of designor any form of construction that conforms to the Code rules.

The Boiler and Pressure Vessel Committee meets regu-larly to consider revisions of the rules, new rules as dictatedby technological development, Code Cases, and requestsfor interpretations. Only the Boiler and Pressure VesselCommittee has the authority to provide official interpreta-tions of this Code. Requests for revisions, new rules, CodeCases, or interpretations shall be addressed to the Secretaryin writing and shall give full particulars in order to receiveconsideration and action (see Mandatory Appendix cov-ering preparation of technical inquiries). Proposed revi-sions to the Code resulting from inquiries will be presentedto the Main Committee for appropriate action. The action

of the Main Committee becomes effective only after con-firmation by letter ballot of the Committee and approvalby ASME.

Proposed revisions to the Code approved by the Commit-tee are submitted to the American National Standards Insti-tute and published at http://cstools.asme.org/csconnect/public/index.cfm?PublicReviewpRevisions to invite com-ments from all interested persons. After the allotted timefor public review and final approval by ASME, revisionsare published annually in Addenda to the Code.

Code Cases may be used in the construction of compo-nents to be stamped with the ASME Code symbol begin-ning with the date of their approval by ASME.

After Code revisions are approved by ASME, they maybe used beginning with the date of issuance shown onthe Addenda. Revisions, except for revisions to materialspecifications in Section II, Parts A and B, become manda-tory six months after such date of issuance, except forboilers or pressure vessels contracted for prior to the endof the six-month period. Revisions to material specifica-tions are originated by the American Society for Testingand Materials (ASTM) and other recognized national orinternational organizations, and are usually adopted byASME. However, those revisions may or may not haveany effect on the suitability of material, produced to earliereditions of specifications, for use in ASME construction.ASME material specifications approved for use in eachconstruction Code are listed in the Guidelines for Accept-able ASTM Editions in Section II, Parts A and B. TheseGuidelines list, for each specification, the latest editionadopted by ASME, and earlier and later editions consideredby ASME to be identical for ASME construction.

The Boiler and Pressure Vessel Committee in the formu-lation of its rules and in the establishment of maximumdesign and operating pressures considers materials, con-struction, methods of fabrication, inspection, and safetydevices.

The Code Committee does not rule on whether a compo-nent shall or shall not be constructed to the provisions ofthe Code. The Scope of each Section has been establishedto identify the components and parameters considered bythe Committee in formulating the Code rules.

Questions or issues regarding compliance of a specificcomponent with the Code rules are to be directed to the

xii

ASME Certificate Holder (Manufacturer). Inquiries con-cerning the interpretation of the Code are to be directedto the ASME Boiler and Pressure Vessel Committee.ASME is to be notified should questions arise concerningimproper use of an ASME Code symbol.

The specifications for materials given in Section II areidentical with or similar to those of specifications publishedby ASTM, AWS, and other recognized national or interna-tional organizations. When reference is made in an ASMEmaterial specification to a non-ASME specification forwhich a companion ASME specification exists, the refer-ence shall be interpreted as applying to the ASME materialspecification. Not all materials included in the materialspecifications in Section II have been adopted for Codeuse. Usage is limited to those materials and grades adoptedby at least one of the other Sections of the Code for applica-tion under rules of that Section. All materials allowed bythese various Sections and used for construction within thescope of their rules shall be furnished in accordance withmaterial specifications contained in Section II or referencedin the Guidelines for Acceptable ASTM Editions in SectionII, Parts A and B, except where otherwise provided in CodeCases or in the applicable Section of the Code. Materialscovered by these specifications are acceptable for use initems covered by the Code Sections only to the degreeindicated in the applicable Section. Materials for Code useshould preferably be ordered, produced, and documentedon this basis; Guideline for Acceptable ASTM Editions inSection II, Part A and Guideline for Acceptable ASTMEditions in Section II, Part B list editions of ASME andyear dates of specifications that meet ASME requirementsand which may be used in Code construction. Materialproduced to an acceptable specification with requirementsdifferent from the requirements of the corresponding speci-fications listed in the Guideline for Acceptable ASTMEditions in Part A or Part B may also be used in accordancewith the above, provided the material manufacturer or ves-sel manufacturer certifies with evidence acceptable to theAuthorized Inspector that the corresponding requirementsof specifications listed in the Guideline for AcceptableASTM Editions in Part A or Part B have been met.

STATEMENT OF POLICY

ON THE USE OF CODE SYMBOLS AND

CODE AUTHORIZATION IN ADVERTISING

ASME has established procedures to authorize qualifiedorganizations to perform various activities in accordancewith the requirements of the ASME Boiler and PressureVessel Code. It is the aim of the Society to provide recogni-tion of organizations so authorized. An organization hold-ing authorization to perform various activities inaccordance with the requirements of the Code may statethis capability in its advertising literature.

Organizations that are authorized to use Code Symbolsfor marking items or constructions that have been con-structed and inspected in compliance with the ASME Boilerand Pressure Vessel Code are issued Certificates of Autho-rization. It is the aim of the Society to maintain the standingof the Code Symbols for the benefit of the users, theenforcement jurisdictions, and the holders of the symbolswho comply with all requirements.

Based on these objectives, the following policy has beenestablished on the usage in advertising of facsimiles of thesymbols, Certificates of Authorization, and reference toCode construction. The American Society of MechanicalEngineers does not approve, certify, rate, or

STATEMENT OF POLICY

ON 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 Sectionof the Code.

Markings such as ASME, ASME Standard, or anyother marking including ASME or the various Code

xiii

endorse any item, construction, or activity and there shallbe no statements or implications that might so indicate. Anorganization holding a Code Symbol and/or a Certificate ofAuthorization may state in advertising literature that items,constructions, or activities are built (produced or per-formed) or activities conducted in accordance with therequirements of the ASME Boiler and Pressure VesselCode, or meet the requirements of the ASME Boiler andPressure Vessel Code.

The ASME Symbol shall be used only for stamping andnameplates as specifically provided in the Code. However,facsimiles may be used for the purpose of fostering theuse of such construction. Such usage may be by an associa-tion or a society, or by a holder of a Code Symbol whomay also use the facsimile in advertising to show thatclearly specified items will carry the symbol. General usageis permitted only when all of a manufacturers items areconstructed under the rules.

The ASME logo, which is the cloverleaf with the lettersASME within, shall not be used by any organization otherthan ASME.

Symbols shall not be used on any item that is not con-structed in accordance with all of the applicable require-ments of the Code.

Items shall not be described on ASME Data ReportForms nor on similar forms referring to ASME that tendto imply that all Code requirements have been met when,in fact, they have not been. Data Report Forms coveringitems not fully complying with ASME requirements shouldnot refer to ASME or they should clearly identify all excep-tions to the ASME requirements.

2007 SECTION II, PART D (CUSTOMARY)

SUBPART 1STRESS TABLES

STATEMENT OF POLICY ON INFORMATIONPROVIDED IN THE STRESS TABLES

The purpose of this Statement of Policy is to clarify whichinformation in the stress tables is mandatory and which isnot. The information and restrictions provided in the Notesfound throughout the various stress tables provided in Subpart1 of Section II, Part D are mandatory. It is vital to recognizethat lines of information in Tables 1A, 1B, 2A, 2B, 3, and 4frequently have essential information referenced in the Notescolumn. These Notes are organized as follows:

(a) EXX: defining onset of values based on successfulexperience in service

(b) GXX: general requirements(c) HXX: heat treatment requirements(d) SXX: size requirements(e) TXX: defining onset of time-dependent behavior(f) WXX: welding requirements

The specifications and grades or types, coupled with theassigned Notes for each line, provide the complete descriptionof material in the context of the allowable stresses or designstress intensities. Additional requirements for particular typesof construction must also be obtained from the rules governingthe construction.

In Tables 1A and 2A, the infor
