FOREWORD*

In 1911, The American Society of Mechanical Engineers established the Boiler and Pressure Vessel Committee to for-mulate standard rules for the construction of steam boilers and other pressure vessels. In 2009, the Boiler and PressureVessel Committee was superseded by the following committees:

(a) Committee on Power Boilers (I)(b) Committee on Materials (II)(c) Committee on Construction of Nuclear Facility Components (III)(d) Committee on Heating Boilers (IV)(e) Committee on Nondestructive Examination (V)(f) Committee on Pressure Vessels (VIII)(g) Committee on Welding, Brazing, and Fusing (IX)(h) Committee on Fiber-Reinforced Plastic Pressure Vessels (X)(i) Committee on Nuclear Inservice Inspection (XI)(j) Committee on Transport Tanks (XII)(k) Technical Oversight Management Committee (TOMC)Where reference is made to “the Committee” in this Foreword, each of these committees is included individually and

collectively.The Committee’s function is to establish rules of safety relating only to pressure integrity, which govern the

construction** of boilers, pressure vessels, transport tanks, and nuclear components, and the inservice inspection of nu-clear components and transport tanks. The Committee also interprets these rules when questions arise regarding theirintent. The technical consistency of the Sections of the Code and coordination of standards development activities of theCommittees is supported and guided by the Technical Oversight Management Committee. This Code does not addressother safety issues relating to the construction of boilers, pressure vessels, transport tanks, or nuclear components, orthe inservice inspection of nuclear components or transport tanks. Users of the Code should refer to the pertinent codes,standards, laws, regulations, or other relevant documents for safety issues other than those relating to pressure integ-rity. Except for Sections XI and XII, and with a few other exceptions, the rules do not, of practical necessity, reflect thelikelihood and consequences of deterioration in service related to specific service fluids or external operating environ-ments. In formulating the rules, the Committee considers the needs of users, manufacturers, and inspectors of pressurevessels. The objective of the rules is to afford reasonably certain protection of life and property, and to provide a marginfor deterioration in service to give a reasonably long, safe period of usefulness. Advancements in design and materialsand evidence of experience have been recognized.

This Code contains mandatory requirements, specific prohibitions, and nonmandatory guidance for construction ac-tivities and inservice inspection and testing activities. The Code does not address all aspects of these activities and thoseaspects that are not specifically addressed should not be considered prohibited. The Code is not a handbook and cannotreplace education, experience, and the use of engineering judgment. The phrase engineering judgment refers to technicaljudgments made by knowledgeable engineers experienced in the application of the Code. Engineering judgments mustbe consistent with Code philosophy, and such judgments must never be used to overrule mandatory requirements orspecific prohibitions of the Code.

The Committee recognizes that tools and techniques used for design and analysis change as technology progressesand expects engineers to use good judgment in the application of these tools. The designer is responsible for complyingwith Code rules and demonstrating compliance with Code equations when such equations are mandatory. The Codeneither requires nor prohibits the use of computers for the design or analysis of components constructed to the

requirements of the Code. However, designers and engineers using computer programs for design or analysis are cau-tioned that they are responsible for all technical assumptions inherent in the programs they use and the application ofthese programs to their design.The rules established by the Committee are not to be interpreted as approving, recommending, or endorsing any pro-

prietary or specific design, or as limiting in any way the manufacturer’s freedom to choose any method of design or anyform of construction that conforms to the Code rules.The Committee meets regularly to consider revisions of the rules, new rules as dictated by technological development,

Code Cases, and requests for interpretations. Only the Committee has the authority to provide official interpretations ofthis Code. Requests for revisions, new rules, Code Cases, or interpretations shall be addressed to the Secretary in writingand shall give full particulars in order to receive consideration and action (see Submittal of Technical Inquiries to theBoiler and Pressure Vessel Standards Committees). Proposed revisions to the Code resulting from inquiries will be pre-sented to the Committee for appropriate action. The action of the Committee becomes effective only after confirmationby ballot of the Committee and approval by ASME. Proposed revisions to the Code approved by the Committee are sub-mitted to the American National Standards Institute (ANSI) and published at http://go.asme.org/BPVCPublicReview toinvite comments from all interested persons. After public review and final approval by ASME, revisions are published atregular intervals in Editions of the Code.The Committee does not rule on whether a component shall or shall not be constructed to the provisions of the Code.

The scope of each Section has been established to identify the components and parameters considered by the Committeein formulating the Code rules.Questions or issues regarding compliance of a specific component with the Code rules are to be directed to the ASME

Certificate Holder (Manufacturer). Inquiries concerning the interpretation of the Code are to be directed to the Commit-tee. ASME is to be notified should questions arise concerning improper use of an ASME Certification Mark.When required by context in this Section, the singular shall be interpreted as the plural, and vice versa, and the fem-

inine, masculine, or neuter gender shall be treated as such other gender as appropriate.

STATEMENT OF POLICY ON THE USE OF THE CERTIFICATIONMARK AND CODE AUTHORIZATION IN ADVERTISING

ASME has established procedures to authorize qualified organizations to perform various activities in accordancewith the requirements of the ASME Boiler and Pressure Vessel Code. It is the aim of the Society to provide recognitionof organizations so authorized. An organization holding authorization to perform various activities in accordance withthe requirements of the Code may state this capability in its advertising literature.

Organizations that are authorized to use the Certification Mark for marking items or constructions that have beenconstructed and inspected in compliance with the ASME Boiler and Pressure Vessel Code are issued Certificates ofAuthorization. It is the aim of the Society to maintain the standing of the Certification Mark for the benefit of the users,the enforcement jurisdictions, and the holders of the Certification Mark who comply with all requirements.

Based on these objectives, the following policy has been established on the usage in advertising of facsimiles of theCertification Mark, Certificates of Authorization, and reference to Code construction. The American Society of MechanicalEngineers does not “approve,” “certify,” “rate,” or “endorse” any item, construction, or activity and there shall be no state-ments or implications that might so indicate. An organization holding the Certification Mark 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 the requirements of the ASME Boiler and Pressure Vessel Code,”or “meet the requirements of the ASME Boiler and Pressure Vessel Code.”An ASME corporate logo shall not be usedby any organization other than ASME.

The Certification Mark shall be used only for stamping and nameplates as specifically provided in the Code. However,facsimiles may be used for the purpose of fostering the use of such construction. Such usage may be by an association ora society, or by a holder of the Certification Mark who may also use the facsimile in advertising to show that clearly spe-cified items will carry the Certification Mark. General usage is permitted only when all of a manufacturer’s items areconstructed under the rules.

STATEMENT OF POLICY ON THE USE OF ASME MARKING TOIDENTIFY MANUFACTURED ITEMS

The ASME Boiler and Pressure Vessel Code provides rules for the construction of boilers, pressure vessels, and nuclearcomponents. This includes requirements for materials, design, fabrication, examination, inspection, and stamping. Itemsconstructed in accordance with all of the applicable rules of the Code are identified with the official Certification Markdescribed in the governing Section of the Code.

Markings such as “ASME,” “ASME Standard,” or any other marking including “ASME” or the Certification Mark shall notbe used on any item that is not constructed in accordance with all of the applicable requirements of the Code.

Items shall not be described on ASME Data Report Forms nor on similar forms referring to ASME that tend to implythat all Code requirements have been met when, in fact, they have not been. Data Report Forms covering items not fullycomplying with ASME requirements should not refer to ASME or they should clearly identify all exceptions to the ASMErequirements.

ð17Þ SUBMITTAL OF TECHNICAL INQUIRIES TO THE BOILER ANDPRESSURE VESSEL STANDARDS COMMITTEES

1 INTRODUCTION

(a) The following information provides guidance to Code users for submitting technical inquiries to the applicableBoiler and Pressure Vessel (BPV) Standards Committee (hereinafter referred to as the Committee). See the guidelineson approval of new materials under the ASME Boiler and Pressure Vessel Code in Section II, Part D for requirements forrequests that involve adding new materials to the Code. See the guidelines on approval of new welding and brazing ma-terials in Section II, Part C for requirements for requests that involve adding new welding and brazing materials (“con-sumables”) to the Code.Technical inquiries can include requests for revisions or additions to the Code requirements, requests for Code Cases,

or requests for Code Interpretations, as described below:(1) Code Revisions. Code revisions are considered to accommodate technological developments, to address admin-

istrative requirements, to incorporate Code Cases, or to clarify Code intent.(2) Code Cases. Code Cases represent alternatives or additions to existing Code requirements. Code Cases are writ-

ten as a Question and Reply, and are usually intended to be incorporated into the Code at a later date. When used, CodeCases prescribe mandatory requirements in the same sense as the text of the Code. However, users are cautioned thatnot all regulators, jurisdictions, or Owners automatically accept Code Cases. The most common applications for CodeCases are as follows:

(-a) to permit early implementation of an approved Code revision based on an urgent need(-b) to permit use of a new material for Code construction(-c) to gain experience with new materials or alternative requirements prior to incorporation directly into the

Code(3) Code Interpretations(-a) Code Interpretations provide clarification of the meaning of existing requirements in the Code and are pre-

sented in Inquiry and Reply format. Interpretations do not introduce new requirements.(-b) If existing Code text does not fully convey the meaning that was intended, or conveys conflicting require-

ments, and revision of the requirements is required to support the Interpretation, an Intent Interpretation will be issuedin parallel with a revision to the Code.(b) Code requirements, Code Cases, and Code Interpretations established by the Committee are not to be considered

as approving, recommending, certifying, or endorsing any proprietary or specific design, or as limiting in any way thefreedom of manufacturers, constructors, or Owners to choose any method of design or any form of construction thatconforms to the Code requirements.(c) Inquiries that do not comply with the following guidance or that do not provide sufficient information for the Com-

mittee’s full understanding may result in the request being returned to the Inquirer with no action.

2 INQUIRY FORMAT

Submittals to the Committee should include the following information:(a) Purpose. Specify one of the following:

(1) request for revision of present Code requirements(2) request for new or additional Code requirements(3) request for Code Case(4) request for Code Interpretation

(b) Background. The Inquirer should provide the information needed for the Committee’s understanding of the In-quiry, being sure to include reference to the applicable Code Section, Division, Edition, Addenda (if applicable), para-graphs, figures, and tables. Preferably, the Inquirer should provide a copy of, or relevant extracts from, the specificreferenced portions of the Code.

xx

(c) Presentations. The Inquirer may desire to attend or be asked to attend a meeting of the Committee to make a for-mal presentation or to answer questions from the Committee members with regard to the Inquiry. Attendance at a BPVStandards Committee meeting shall be at the expense of the Inquirer. The Inquirer’s attendance or lack of attendance ata meeting will not be used by the Committee as a basis for acceptance or rejection of the Inquiry by the Committee. How-ever, if the Inquirer’s request is unclear, attendance by the Inquirer or a representative may be necessary for the Com-mittee to understand the request sufficiently to be able to provide an Interpretation. If the Inquirer desires to make apresentation at a Committee meeting, the Inquirer should provide advance notice to the Committee Secretary, to ensuretime will be allotted for the presentation in the meeting agenda. The Inquirer should consider the need for additionalaudiovisual equipment that might not otherwise be provided by the Committee. With sufficient advance notice to theCommittee Secretary, such equipment may be made available.

3 CODE REVISIONS OR ADDITIONS

Requests for Code revisions or additions should include the following information:(a) Requested Revisions or Additions. For requested revisions, the Inquirer should identify those requirements of the

Code that they believe should be revised, and should submit a copy of, or relevant extracts from, the appropriate require-ments as they appear in the Code, marked up with the requested revision. For requested additions to the Code, the In-quirer should provide the recommended wording and should clearly indicate where they believe the additions should belocated in the Code requirements.

(b) Statement of Need. The Inquirer should provide a brief explanation of the need for the revision or addition.(c) Background Information. The Inquirer should provide background information to support the revision or addition,

including any data or changes in technology that form the basis for the request, that will allow the Committee to ade-quately evaluate the requested revision or addition. Sketches, tables, figures, and graphs should be submitted, as appro-priate. The Inquirer should identify any pertinent portions of the Code that would be affected by the revision or additionand any portions of the Code that reference the requested revised or added paragraphs.

4 CODE CASES

Requests for Code Cases should be accompanied by a statement of need and background information similar to thatdescribed in 3(b) and 3(c), respectively, for Code revisions or additions. The urgency of the Code Case (e.g., project un-derway or imminent, new procedure) should be described. In addition, it is important that the request is in connectionwith equipment that will bear the Certification Mark, with the exception of Section XI applications. The proposed CodeCase should identify the Code Section and Division, and should be written as a Question and a Reply, in the same formatas existing Code Cases. Requests for Code Cases should also indicate the applicable Code Editions and Addenda (if ap-plicable) to which the requested Code Case applies.

5 CODE INTERPRETATIONS

(a) Requests for Code Interpretations should be accompanied by the following information:(1) Inquiry. The Inquirer should propose a condensed and precise Inquiry, omitting superfluous background infor-

mation and, when possible, composing the Inquiry in such a way that a “yes” or a “no” Reply, with brief limitations orconditions, if needed, can be provided by the Committee. The proposed question should be technically and editoriallycorrect.

(2) Reply. The Inquirer should propose a Reply that clearly and concisely answers the proposed Inquiry question.Preferably, the Reply should be “yes” or “no,” with brief limitations or conditions, if needed.

(3) Background Information. The Inquirer should provide any need or background information, such as described in3(b) and 3(c), respectively, for Code revisions or additions, that will assist the Committee in understanding the proposedInquiry and Reply.

If the Inquirer believes a revision of the Code requirements would be helpful to support the Interpretation, the In-quirer may propose such a revision for consideration by the Committee. In most cases, such a proposal is not necessary.

(b) Requests for Code Interpretations should be limited to an Interpretation of a particular requirement in the Code orin a Code Case. Except with regard to interpreting a specific Code requirement, the Committee is not permitted to con-sider consulting-type requests such as the following:

(1) a review of calculations, design drawings, welding qualifications, or descriptions of equipment or parts to de-termine compliance with Code requirements

xxi

(2) a request for assistance in performing any Code-prescribed functions relating to, but not limited to, materialselection, designs, calculations, fabrication, inspection, pressure testing, or installation

(3) a request seeking the rationale for Code requirements

6 SUBMITTALS

(a) Submittal. Requests for Code Interpretation should preferably be submitted through the online Interpretation Sub-mittal Form. The form is accessible at http://go.asme.org/InterpretationRequest. Upon submittal of the form, the In-quirer will receive an automatic e-mail confirming receipt. If the Inquirer is unable to use the online form, theInquirer may mail the request to the following address:

CROSS-REFERENCING AND STYLISTIC CHANGES IN THE BOILERAND PRESSURE VESSEL CODE

There have been structural and stylistic changes to BPVC, starting with the 2011 Addenda, that should be noted to aidnavigating the contents. The following is an overview of the changes:

Subparagraph Breakdowns/Nested Lists Hierarchy

• First-level breakdowns are designated as (a), (b), (c), etc., as in the past.• Second-level breakdowns are designated as (1), (2), (3), etc., as in the past.• Third-level breakdowns are now designated as (-a), (-b), (-c), etc.• Fourth-level breakdowns are now designated as (-1), (-2), (-3), etc.• Fifth-level breakdowns are now designated as (+a), (+b), (+c), etc.• Sixth-level breakdowns are now designated as (+1), (+2), etc.

Footnotes

With the exception of those included in the front matter (roman-numbered pages), all footnotes are treated as end-notes. The endnotes are referenced in numeric order and appear at the end of each BPVC section/subsection.

Submittal of Technical Inquiries to the Boiler and Pressure Vessel Standards Committees

Submittal of Technical Inquiries to the Boiler and Pressure Vessel Standards Committees has been moved to the frontmatter. This information now appears in all Boiler Code Sections (except for Code Case books).

Cross-References

It is our intention to establish cross-reference link functionality in the current edition and moving forward. To facil-itate this, cross-reference style has changed. Cross-references within a subsection or subarticle will not include the des-ignator/identifier of that subsection/subarticle. Examples follow:

• (Sub-)Paragraph Cross-References. The cross-references to subparagraph breakdowns will follow the hierarchy ofthe designators under which the breakdown appears.– If subparagraph (-a) appears in X.1(c)(1) and is referenced in X.1(c)(1), it will be referenced as (-a).– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.1(c)(2), it will be referenced as (1)(-a).– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.1(e)(1), it will be referenced as (c)(1)(-a).– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.2(c)(2), it will be referenced as X.1(c)(1)(-a).

• Equation Cross-References. The cross-references to equations will follow the same logic. For example, if eq. (1) ap-pears in X.1(a)(1) but is referenced in X.1(b), it will be referenced as eq. (a)(1)(1). If eq. (1) appears in X.1(a)(1) butis referenced in a different subsection/subarticle/paragraph, it will be referenced as eq. X.1(a)(1)(1).

INTENTIONALLY LEFT BLANK

PART TGGENERAL REQUIREMENTS

ARTICLE TG-1SCOPE AND JURISDICTION

TG-100 INTRODUCTION

TG-100.1 INTENTThe rules of this Section constitute requirements for

construction and continued service of pressure vesselsfor the transportation of dangerous goods via highway,rail, air, or water. Construction is an all‐inclusive termcomprising materials, design, fabrication, examination, in-spection, testing, certification, and over‐pressure protec-tion. Continued service is an all‐inclusive term referringto inspection, testing, repair, alteration, and recertifica-tion of a transport tank that has been in service. The termpressure vessel refers to the pressure boundary defined bythe geometric scope of this Section and includes, but isnot limited to, the shell, heads, and openings. The termtank refers to the pressure vessel, appurtenances, and ad-ditional components that are covered by the Modal Ap-pendices (see TG-220.1).

The general requirements given in Part TG shall be metfor all vessels within the scope of this Section. In addition,all the applicable requirements of Modal Appendices,which address unique service conditions of the vessel,shall be met.

TG-100.2 APPLICABILITY(a) The rules of this Section apply specifically to pres-

sure vessels intended for transporting dangerous goods(see Mandatory Appendix III) with design pressures ap-propriate for the transportation mode and volumes great-er than 450 L (120 gal).

(b) Pressures normally incident to transportation, in-cluding loading and unloading operations, are to beconsidered.

(c) This Section does not contain rules to cover all de-tails of design and construction, and those aspects thatare not addressed shall not be considered prohibited.Where complete details are not given, the Manufacturer,subject to the acceptance of the Inspector, shall providedetails of design and construction that will be as safe asthose provided by the rules of this Section. In the case

of Class 3 vessels, the Design Certifying Engineer shallperform this function. (For definition of Inspector, seeTG-410.)

TG-100.3 LAWS OR REGULATIONS

The laws or regulations issued by the competentauthority covering the construction and continued serviceof pressure vessels intended for transporting dangerousgoods shall be reviewed to determine if the requirementsare more restrictive than the rules of this Section. Applic-able laws and regulations may contain additional require-ments for pressure vessels used in the transportation ofdangerous goods, which are not addressed in this Section,such as Code of Federal Regulation, Title 49, Parts 100through 185, Transportation.

TG-110 SCOPE

TG-110.1 GEOMETRIC SCOPE OF THE PRESSUREVESSEL

(a) The geometric scope of this Section shall, as a mini-mum, include the pressure‐containing parts of pressurevessels up to and including the following:

(1) the first threaded joint for threaded connections.(2) the face of the first flange for flanged connections.(3) the first sealing surface for proprietary connec-

tions or fittings for which rules are not provided in thisSection.

(4) the welding end connection for the first circum-ferential joint for welded connections to attached piping,valves, and instruments, etc.

(5) the welding pad for attachment of any externalnonpressure attachments such as shipping frames, andhandling points, etc. Parts welded to these pads neednot comply with (b).

(6) pressure‐retaining permanent covers and clo-sures, including seals, bolting, and other mechanical retai-ners at openings.
