2011 Addenda Synopsis – Executive Summary

2011 ASME Code Addenda Synopsis The 2011 Addenda of the ASME Boiler and Pressure Vessel Code was published on July 1, 2011, and includes revisions, additions and errata approved in 2010/2011 by the ASME B&PV Standards Committee. The mandatory implementation date for the 2011 Addenda is six months from the date of publication, or January 1, 2012. As always, the 2011 Addenda may be optionally implemented upon receipt. The most obvious change with the publication of the Addenda is that it is printed on white paper, rather than on colored sheets as has been past practice, and it is printed in its entirety. ASME advises that existing 2010 Edition pages be retained for reference as well as for meeting regulatory or contractual obligations and for historical purposes. You may also notice that “Footnotes” have been replaced by “Endnotes” in the following Code Sections: I; III, Division 1 – Subsections NCA, NB, NC, ND, NG and NH; IV; X, XI and XII. Endnotes are considered part of the Standard. This will be the “last” ASME Boiler and Pressure Vessel Code Addenda. ASME has instituted a new publishing schedule. Addenda have been eliminated. The next Edition of the ASME Code will be published in 2013 and every two years thereafter. Code Case Supplements will continue to be published four times per year and republished as a new Edition on a cycle concurrent with the rest of the Code. Interpretations will be posted on the ASME Web site http://cstools.asme.org/interpretations.cfm in January and July of each year. A “Special Notice” may be posted on the ASME Web site in advance of the 2013 Code Edition to provide approved revisions to Code requirements. Such revisions may be used on the date posted and will become mandatory 6 months after the date of issuance in the next Edition. A “Special Notice” may also include a revision to a Code Case. The superseded version of the Code Case shall not be used. Errata to the Code will also be posted on the ASME Web site to provide corrections to incorrectly published items, or to correct typographical or grammatical errors. Such Errata shall be used on the date posted. Information regarding “Special Notices” and “Errata” is published under the ASME Boiler and Pressure Vessel Code Resources Page at: http://www.asme.org/kb/standards/publications/bpvc-resources or http://cstools.asme.org/BPVErrataAndSpecialNotice.cfm. ASME offers users the option to receive an e-mail notification when additional “Special Notices” or “Errata” are posted on their Web site. This will be especially useful now that annual Addenda will no longer be published. Nearly 600 changes are itemized in this Synopsis. Many of these changes are the result of new technology and/or at the request of Certificate Holders like you. This Synopsis also includes a selection of Code Cases that were newly approved or revised between May 2010 and February 2011. Some of the Cases listed in our Synopsis have not yet been published in hard copy by ASME but are scheduled to be published in an upcoming Supplement, or can be obtained from ASME prior to publication. Please contact the Home Office Staff for further assistance.

This Synopsis was prepared by the HSB Global Standards Code & Standards Staff to provide insights into the intent of these changes, and their potential impact on Code users. Each item that passed the ASME B&PV Standards Committee for the 2011 Addenda was entered into the Synopsis database. The “Subject” and “Description” were created by HSB CT personnel involved with the cognizant Code Section Standards Committee, and each entry was verified that it made it into publication. Commentary on revisions represents HSB CT's opinion of the changes, and is not intended to be an official interpretation of the ASME Code. Every effort was made to accurately describe the addenda changes. However, we caution Code users to always refer to the actual Code rules that apply and to use this document as a supplementary tool to the Code. Please contact HSB CT’s Codes & Standards Group if further background information is desired on any of the revisions or Code Cases published. The following Executive Summary highlights the more noteworthy revisions. We hope you find this information helpful.

General Code Revisions 2011 Addenda 2011 Addenda changes are identified on the pages by a margin note, [a], placed next to the heading of the affected area. Previous revisions to the 2010 Edition are indicated by a [10]. Foreword The replacement of Code Symbol Stamps with the ASME Certification Mark, which is explained in greater detail in subsequent Executive Summary and Synopsis entries, has resulted in various revisions in the Forewords of all Code Sections. Statement of Policy on the Use of the Certification Mark and Code Authorization in Advertising and Statement of Policy on the Use of ASME Marking to Identify Manufactured Items The titles and text of the above Statements have been changed in all Code Sections to reflect the replacement of Code Symbol Stamps with the new ASME Certification Mark. Introduction of the New ASME Certification Mark and “Certification Designators” Since 1972, ASME’s product certification programs (“Code Stamps”) have grown to include companies located in 74 countries. The growth of these programs has presented challenges regarding how to maintain the trademark registrations of ASME’s 28 separate product certification marks across the more than 100 nations in which these marks are currently used on products. In order to streamline the multiple marking processes and more effectively manage its numerous global relationships, ASME has instituted the introduction of a single product certification mark:

New ASME Product Certification Mark




E-2

This single comprehensive mark will replace ASME’s 28 separate certification marks. To maintain a link to the current Code Symbol Stamps, the new “ASME Mark” will be used in conjunction with a “certification designator” to indicate the applicability of the certification. The following is an example of how the new mark is intended to be used on a nameplate (in this case a vessel constructed to Section VIII, Division 2):

ASME states on its website (http://www.asme.org/kb/standards/certification---accreditation/product-certification/single-certification-mark-faq) that the Certification Designator (U, S, N, etc.) must appear directly below the ASME Certification Mark. The Certification Designator may be printed rather than stamped. The rules in the applicable Code Section are to be consulted for further information. Unfortunately, the global replacement of “code symbol stamp” with “ASME Certification Mark” and “Certification Designator” did not go smoothly. If you look in any of the Code books’ 2011 Addenda (including Section VIII, Div. 2), you will NOT find any figures or tables showing the placement of the Certification Designator. To add to the confusion, the only Code Sections where the placement of the Certificate Designator is specifically descibed are Section X for “RP” (RS-100(a)) and Section XII for “T” (TS-100(g)). Certificate Holders may begin to use the new ASME Certification Mark anytime after July 1, 2011. Until the end of 2011, new applicants will continue to receive “old” stamps (U, S, N, etc.) unless a new “ASME Mark” stamp is requested. Current Certificate Holders may request the new “ASME Mark” stamp now. Current “stampholders” will receive the new “ASME Mark” free of charge. Newly certified companies will pay the regular stamp fees. New “ASME Mark” stamps will be available in 1/2-inch and 3/4-inch sizes. The size should be specified when ordering the




E-3

new stamps from ASME. Additional “ASME Mark” stamps may be purchased for an additional fee. “Old” stamps (U, S, N, etc.) may be used until January 1, 2013. As of that date, all of the “old” stamps must be returned to ASME. Certificates of Authorization are NOT required to be returned to ASME. Certified companies will continue to receive a separate CERTIFICATE for each category of equipment and SCOPES of the Certificates will not change; however, certificate numbers will. As of January 1, 2012, Certificates will be redesigned to show the new ASME Certification Mark. During the 18-month transition period (July 1, 2011 through December 31, 2012) old and new symbols are considered equivalent. (e.g. an old “U2” as a Part + a new “ASME Mark” with “U2” designator).

Timeline July 1, 2011 Companies may begin using the new “ASME Certification Mark”

with “Certification Designator” January 1, 2012 1. Companies will begin receiving the new “ASME Certification

Mark”. 2. “Old” and “new” symbols are considered equivalent and may be

used until December 31, 2012. 3. Certificates will be redesigned to show the new “ASME

Certification Mark”. January 1, 2013 “Old” symbols may no longer be used and must be returned to

ASME.

Code Revisions by Sections Section I New Certification Mark ASME is eliminating individual stamps (such as S, M) for each Code with an accreditation program and moving to a single certification mark for all codes. The new Mark is comprised of the traditional cloverleaf with the letters "ASME". Beneath this new mark, the Manufacturer would then add a "Certification Designator", which will identify the particular construction code they are working to. For Section I, the Designator that will appear on the nameplate directly under the Certification Mark will be "S”, "M", "E", "A", "PP" or "V". PWHT Requirements of P-No.1 Materials A major highlight of the revisions in the post weld heat treatment requirements for P-No.1 materials in the 2009 Addenda was the extension of the PWHT exemption based on thickness up to 3/4 inch (19 mm) for all groove welds (butt or corner welds) or combination groove and fillet welds, regardless of the type of joint (circumferential / longitudinal). However, it was recognized later that the some of the existing Notes of Table PW-39 could potentially override the exemption provided by Note (a) (1). Notes (a) (1) & (2) are now further revised in the 2011 Addenda to allow PWHT exemption purely based on nominal thickness as defined in PW-39.3. In addition, Notes (a) (3), (a) (4), (a) (6), (a) (8) though (a) (10), (a) (12), (a) (13) and (c) are deleted and the retained notes are renumbered. Many of these deleted notes were written to offer very specific exemptions from PWHT for P-No.1 materials. So, their deletion will make the Table PW-39-1 quite generic and could possibly allow more welds to be now exempted from PWHT, as the basis for exemption is now solely dependent on the nominal thickness as referred in the General Notes (a) (1) & (2). Paragraph PW-39.3 is also revised by adding individual definitions for “Nominal Thickness" for different types of welds. PWHT Heating and Cooling Rates A new Non-mandatory Appendix (A-101) is added to address sub-critical post weld heat treatment heating and cooling rates for Section I materials, as general guidance. Welder Qualification Section I now allows UT for welder qualification. PW-28.2 is revised to allow "volumetric NDE" for welder performance qualification. This revision not only eliminates the "radiography only" restriction on the NDE method but also makes the paragraph consistent with Section IX rules.




E-5

Manufacturer's Data Report Forms The previous requirements for recording the Authorized Inspector’s National Board Commission and Endorsement on a Manufacturer’s Data Report (MDR) [only when it was registered with the National Board] were in conflict with the requirements of ASME QAI-1 and NB-263, Rev. 3 "Rules for National Board In-service and New Construction Commissioned Inspectors", paragraphs RN-2.2 and 2.3. Rules are now simplified for the Authorized Inspector to complete the “Certificate of Shop Inspection” and the “Certificate of Field Assembly Inspection” portions of the MDR by requiring only the Inspector’s signature, National Board Commission number and the Endorsement. The need to indicate State / Provincial Commission information has been eliminated. Each Data Report Form and the Guide for completing the MDR are updated to reflect this change. Section II, Parts A, B & C Twenty (20) SA-, seven (7) SB-, and six (6) SFA- specifications were updated. Section II, Part A AS 1548-2008 has been adopted and has a different grade designation system. The corresponding changes in Sections II Part D, VIII Division 1 and IX were also made. The previously-adopted version of AS-1548 (1995) has been made obsolete. Section II, Part B SB-135 C27000, C27400 and C28000 copper tube has reduced the lead levels for future accommodation of more stringent regulations for potable hot water systems. SB-247 aluminum alloy forging specification has been updated to ASTM B247-09. The older ASME tradition of only listing in the specification the alloys/tempers that were used in Boiler & Pressure Vessel Code is no longer being continued – all alloys in the ASTM specification are published in the ASME specification. However, not all alloys/tempers are permitted for use – it is the construction Code and/or Section II, Part D that control the material usage. Section II, Part C Adopted AWS A5.14/A5.14M:2009 – three new classifications have been added: ERNiCr-7, ERNiCrFe-13 and ERNiCrMo-22. Section II, Part D Table 1A Added SA-213 TP347LN and SA-312 TP-347LN for Section VIII, Division 1 use to 1100°F/593°C. This addition incorporates Code Case 2196-1. Added SA-451 J92800 (CPF3M) and J92900 (CPF8M) for Section VIII, Division 1 use to 800°F/427°C. This addition incorporates Code Case 2456.




E-6

Tables 1A, 5A, U and Y-1 Added SA-841, Grade A Class 1 and Grade B, Class 2 TMCP (thermo-mechanical control process) steels to Tables 1A, 5A, U, and Y-1 for Section VIII, Divisions 1, 2 and 3 use. This is special class of carbon steel material with particular thermal treatments for higher mechanical properties, and has special controls during manufacture. Table 1B Changed minimum tensile strength of SB-359-C12200/H55 from 30 ksi to 36 ksi and changed minimum yield strength from 9 ksi to 30 ksi to be consistent with H55 temper values listed in SB-359. Increased allowable stress values up to more than a factor of 3. Section V T-292(b) The intent of requirements that the radiographic technique details must either be attached to or included in the radiographic review form has been clarified. T-282.2 A possible problem was noted with the wording of T-282.2 regarding where density checks are made when using hole-type IQIs. The Committee decided that density checks for hole-type IQIs should be made adjacent to the essential hole. Additional editorial clarifications are included in the revision. Other affected subparagraphs include T-277.3, T-282.1, T-283.1, and T-283.2. Article 4 Mandatory Appendices Previous Article 4 Mandatory Appendices VI, VII and VIII have been redesignated by errata as VII, VIII and IX, respectively. T-494 & T-594 Articles 4 and 5 did not address storage media requirements for retention of records generated by computerized ultrasonic examination techniques. New paragraphs T-494 and T-594 address those requirements. Section IX

Added Diffusion Welding (DFW) This is the incorporation of Code Case 2621-1 into Section IX which permits the use of diffusion welding (DFW) as a method for material joining. Diffusion welding (DFW) is a solid-state welding process producing a weld between multiple layers of sheet or plate by the application of pressure at elevated temperature with no macroscopic deformation or relative motion of the work pieces. A solid filler




E-7

metal may be inserted between the faying surfaces. This definition was added to QW/QB-492 as "welding, diffusion". The most important aspects of this process are temperature, time at temperature, and the contact between the two faying surfaces being joined. This process has been used successfully for many years in the construction of micro-channel heat exchangers. Note: A faying surface is defined as: In welding, that surface of a member which is in contact, or in close proximity to, another member to which is to be joined.] Requirements for qualification for DFW Welding Operators have been added and refer to QW-185 for testing requirements. QW-251.1 was revised to include the new QW-266 listing of the eight (8) essential variables for qualification of DFW Welding Procedure Specifications. . There are no nonessential or supplementary essential variables. Revised Laser Beam Welding (LBW) Variables When LBW was first introduced into the Code over two decades ago, the essential variables were intentionally made extremely restrictive until more experience could be gained with this process. A thorough reevaluation of the variables has prompted changes to QW-264 to address the current level of technology and good engineering practice for this welding process. Revised Simultaneous Performance Qualifications QW-300.3, 2nd paragraph, was revised to permit an SWPS (AWS Standard Welding Procedure Specification) to support the essential variables used when conducting simultaneous welder performance qualifications, and to clarify that only the essential variables must be in agreement between the participating organizations and supported by a PQR or SWPS. Revised for Unlisted Base Metals QW-420 was clarified to explain that an unlisted base metal with the same UNS Number as a base metal listed in QW/QB-422 may, for the purposes of procedure qualification, be considered as assigned the same P-Number and the same tensile strength as the listed material. Added Paragraph on ASTM Materials Changes in the 2009 Addenda deleted all references to S-Numbers. Unfortunately, a very useful portion of QW-420.2 that addressed the assignment of [what was then] S-Numbers to ASTM materials was lost. This revision restores that provision but embraces the "P-Number-only philosophy". Revised QW-510 The word "volumetric" has replaced the word "radiographic" in QW-510(d)(15) and (e) for consistency with QW-302.2 and QW-304.1 to allow the use of ultrasonic examination methods for the discrete demonstration.


Synopsis of the 2011 Addenda to the ASME BPV Code - Section I Power BoilersHSB Code Services

Tuesday, November 22, 2011 Page 1

Foreword Revision Former Mandatory Appendix I - "Submittal of Technical Inquiries to the Boiler and Pressure Vessel Committee" has been revised and moved to the Front Matter (after the "Foreword" just before "Personnel") of the Code Book. It shall continue to be treated as mandatory. This action is consistent with action taken for all other Code Sections with the 2011 Addenda.

Numerous Paragraphs Revision ASME is eliminating individual stamps (such as S, M) for each Code with an accreditation program and moving to a single certification mark for all codes. The reason for doing this is that presently ASME must register each of their 28 stamps in over 100 countries, which is becoming a very costly administrative burden. The solution is to replace the 28 stamps with a single certification mark, which will comprise the Cloverleaf with the letters "ASME". Beneath this new mark, the Manufacturer would then add a "Certification Designator", which will identify the particular construction code they are working to. For Section I , the Designator that will appear on the nameplate directly under the Certification Mark will be "S" , "M", "E", "A", "PP" or "V". The net result of this action is that the following phrase changes occurred in several places in Section I. "Code Symbol", "ASME Code Symbol" becomes "Certification Mark" "Code stamped" becomes "stamped with the Certification Mark" "Code stamp holder" becomes "Certificate holder" "Certificate of Authorization Holder" becomes "Certificate holder" "S Stamp" becomes "Certification Mark with S Designator" "Appropriate Code Symbol" becomes "Certification Mark with appropriate Designator" See the "Executive Summary" of this Synopsis for further details.

Fig-PG-33.2 Errata This action corrects sketches (h) and (i) of Fig. PG-33.2 that show double-sided welded joints with unshaded squares at the mid-wall root giving a false appearance of failure to achieve full penetration.

Figures PG-58.3.1 (a), (b) and (c)

Revision The Figures contain references to other paragraphs that are not mentioned in PG-58. References to these paragraphs (for example PG-60, PG-68 or PG-71) in these figures are to provide guidance to the user to find the technical requirements. A general note is added to these figures stating: " This figure provides references to other paragraphs of the Code for information only". In addition, reference to PG-58.3.7 for vents, drains, and level indication are added to Figure PG-58.3.1 (a).

Fig. PG-58.3.3 Revision The Figure is revised by adding a control valve for the recirculation pump (if used).PG-5.1 Errata Lower case "m" in the word "manufacturer" was capitalized.PG-8.4.1.2 Revision This action corrected the reference of PG-67.7 (which was deleted in the 2009 Addenda) in

PG-8.4.1.2 from "PG-67.7" to "PG-73.3.4".PG-16.6 Addition Further to the clarification made by ASME that "Forewords are not part of the Code", a

proposal was developed to clean up the Forewords of all Code books by moving those portions of previous Forewords, that are often presumed to be mandatory and enforceable, into the main body of the Code books. This action complements that effort by copying the words on tolerances that were in the Foreword to Section I into a new Paragraph PG-16.6.

PG-22.1 Revision The term “average stress” is deleted from PG-22.1 as it is not defined anywhere in the Code. Words are now added to PG-22.1 to make it clear that the Code does not address loads other than those from pressure and static head. It also now points the designer to PG-16.1 for general guidance on additional loads.

PG-27.4.4 Revision It is important to note that "Weld Strength" referred in PW-15 and "Strength Weld" referred in paragraphs PG-27.4.4 Note 4 & A-317.3 (d) Note 4 are not synonymous terms. The purposes of "e" and "f" factors in PG-27.4.4 Note 4 & A-317.3 (d) Note 4 are to ensure certain minimum strength to the tube ends when the tubes are attached by expanding. Therefore the term "Strength Weld" in this context merely refers to a tube attachment that relies on the weld alone and does not require expanding. On the other hand, PW-15 while dealing with "Weld Strength", is directed at providing adequate weld strength to attach the elements of reinforcement.

Words added at the end of PG-27.4.4 Note 4 & A-317.3 (d) Note 4 now clarify that "Strength Welds" mean that the welds need to comply with the minimum weld size requirements of PW-16. An Intent Interpretation was also issued and awaiting publication.

PG-28 Revision This action basically brings the external pressure design rules of PFT-51 to a general paragraph of the Code book to make them more generic and applicable for all cylindrical components under external pressure, not only for furnaces and tubes of firteube boilers. As an example, these rules could now be used to design cylindrically shaped drum heater (or "keep up") coils. The existing PG-28 has been re-designated as "PG-28.2" and rolled into the new "PG-28" as a sub-paragraph. Paragraph "PFT-50" has been revised and moved to paragraph "PG-28.1" and "PFT-51" has been revised and moved to paragraph "PG-28.3". In addition, the references made to PFT-50 & PFT-51 throughout the book have now changed to their appropriate counterparts in PG-28.

PG-31.2 Revision The symbol for gasket moment arm h[sub g] in PG-31.2 has been revised to make it consistent with the way it is shown in Figure PG-31.

PG-32.1.4(a) Revision The original intent of this paragraph was to limit the maximum opening size (to be exempted from compensation calculations) as the larger of : "d max" or the smaller of 1/4 times the inside diameter of the shell or header, or 2 3/8" (60 mm). This editorial revision improves the overall readability of the paragraph without changing the original intent.

PG-33 Revision When a nozzle as shown in Fig. PG-33.2, Sketches (d), (e-1), (f), (g), (h), and (i) is inserted into the vessel wall with the nozzle material of lower strength compared to the vessel wall, the nozzle reinforcement equations in Fig. PG-33.1 for the area available in the shell, “A1,” do not compensate for the lower strength of the inserted nozzle beyond the nozzle neck (t[sub n]). While PG-37.1 requires that the lower strength material needs to be adjusted (by taking the ratio of allowable stresses of the two different materials into account) the revision now made to the equations for "A1" make it obvious and handy for the designer as to what the intent of the Code is. In addition, a new term "w[sub d]" is added to PG-33.3 and Figure PG-33.2 as a part of this action. Editorial revisions are also made to the examples A-66 and A-69 with regard to the addition of the term "w[sub d]".

PG-33.1, A-67 Revision The words "for nozzle wall inserted through the vessel wall" in the definition of "fr1" in PG-33.3 appear to limit "fr1" only to those situations where the nozzle wall is inserted through the vessel wall, while equations for abutting nozzles in Figure PG-33.1 use the stress ratio "fr1". This revision deletes the words "for nozzle wall inserted through the vessel wall" from the definition of "fr1" in PG-33.3 to avoid the possible confusion. Also a mistake in the formula for "A4" in the example problem A-67 is corrected by squaring the term "WL[sub 3]" .

PG-49.1 Revision A new requirement is added to PG-49.1 to limit the allowable stress to 7500 psi [51.7 MPa] for stays in steam locomotives to make it consistent with US Federal Railroad Administration requirements.

PG-52.3 Revision Previously, PG-52.3 did not clearly indicate clearly whether the designer is permitted to establish an equivalent longitudinal efficiency for circumferential ligaments by doubling the circumferential efficiency for use in the design formula of PG-27.2.2, A-125 & A-317.

An equation is now added to PG-52.3 to establish equivalent longitudinal efficiency for circumferential ligaments. Also rules were added to PG-52.6 to make it very clear that the lesser value of the actual or equivalent longitudinal ligament efficiencies shall be used to calculate the minimum required thickness and maximum allowable working pressure.




PG-53.3 Revision In PG-53.3, the Figure is re-designated as Fig. PG-53.3 in order to keep the figure and the referencing paragraph consistent.

PG-60.1.6 Revision A new requirement to provide manual operational access from the floor is added to PG-60.1.6. This will increase /ensure the likelihood of periodic blowing down of gage glasses in a safer manner.

PG-67.2.7 Revision A new paragraph (PG-67.2.7) was added in the 2010 Edition to address the following condition. When the boiler is arranged with steam generating surface downstream of superheater section in the gas path, the steam generated (when all valves are blowing) due to the shifting of heat capacity from superheater section to the downstream components can exceed the maximum steaming capacity defined at the MAWP of the boiler.

This action brings additional clarity to those words by placing "in the gas stream" in parentheses to make it clear that the word "downstream" is related to the position in the gas stream, not the water/steam flow path. In addition, the present paragraphs PG-67.2.2 through PG-67.2.7 have been renumbered to be the subparagraphs of PG-67.2.1.

PG-72.2 Errata (1) An editorial correction is made to the table in PG-72.2 by inserting the "greater than" symbol ">" in front of the number "70" in the second row; (2) Cross-references to "A-300" are corrected to "A-301" & "A-302".

PG-105 Errata The reference to "A-300" has been corrected to "A-301" & "A-302".PG-106 Revision The word "steel" is deleted where it used to appear before the word " economizer" to clarify

that Section I rules apply to all Economizers whether they are "steel" or not, if they are required to be built to Section I requirements.

PG-112.2.4 Errata A new paragraph was added to PG-112.2.3 in the 2010 Edition but incorrectly labelled as "PG-112.2.4". This errata item fixes that error. Also the existing paragraphs PG-112.2.5 through PG-112.2.9 are now renumbered as result of this action.

Table PG-20 Errata The upper temperature "425 deg. F" was changed to "1425 deg. F".

PW-28.2 Revision PW-28.2 is revised to allow "volumetric NDE" for welder performance qualification. This revision not only eliminates the "radiography only" restriction on the NDE method but also makes the paragraph consistent with Section IX rules.

PW-39.3 Addition A new Nonmandatory Appendix (A-101) is added to Section I to address sub-critical post weld heat treatment heating and cooling rates for Section I materials, as general guidance.

PW-40.3(f) Revision In addition to the half bead method, as a result of this revision, Manufacturers and users can now choose from half bead (PW-40.3.4(f)(1)) or temper bead (PW-40.3.4(f)(2)) methods to perform weld repairs to P-No.3 Group Nos. 1 & 2 materials without having to repeat PWHT.

PW-53 Revision PW-53 has been editorially corrected to improve the overall clarity of the paragraph. Specific exemptions and requirements are all now stated in PW-53.1. The previous "PW-53.3" is rolled into "PW-53.1" and the paragraphs subsequent to PW-53.3 have been renumbered. This revision clarifies that all attachment welds are exempted from the testing requirements of PW-53. Note that Interpretation I-10-13 was also published in Volume 61 with the 2011 Addenda to further clarify some of the requirements of PW-53.

Table PW-39 Revision A major highlight of the revisions in the post weld heat treatment requirements for P-No.1 materials in the 2009 Addenda was the extension of the PWHT exemption based on thickness up to 3/4 inch (19 mm) for all groove welds (butt or corner welds) or combination groove and fillet welds, regardless of the type of joint (circumferential / longitudinal). However, it was recognized later that the Notes (a)(3), (a)(4), (a)(6), (a)(8) though (a)(10), (a)(12), (a)(13) and (c) could potentially override the exemption provided by Note (a)(1). As an example, Note (a)(9) limits the fillet welded nozzles to a maximum finished opening size of 2 inches (50 mm) and this means a boiler with couplings over NPS 2 attached with double-sided fillet welds require PWHT regardless of the thickness.

Notes (a)(1) & (2) are now revised further to allow PWHT exemption purely based on nominal thickness as defined in PW-39.3. In addition, Notes (a)(3), (a)(4), (a)(6), (a)(8) though (a)(10), (a)(12), (a)(13) and (c) are deleted and the retained notes are renumbered. Many of these deleted notes were written to offer very specific exemptions from PWHT for P-No.1 materials. So, their deletion will make the Table PW-39-1 quite generic and could possibly allow more welds to be exempted, as the basis for exemption is now solely dependent on the nominal thickness as referred in the General Notes (a) (1) & (2).

Paragraph PW-39.3 is also revised by adding individual definitions for “Nominal Thickness" for different types of welds. Except for ligaments where the spacing between centers is less than twice the average diameter, the definition of nominal thickness for a combination groove plus fillet weld is revised from "groove depth plus fillet weld throat" to "the depth of the groove weld or the fillet throat dimension, whichever is greater". This revised definition is consistent with the definition of nominal thickness in Section VIII.

THE REFERENCE TO PW-39.4 IN NOTE (a)(1) & (2) OF TABLE PW-39.1 FOR NOMINAL THICKNESS IS INCORRECT. THE CORRECT REFERENCE IS PW-39.3.

PHRSG-3.4 Revision The word "quick-opening" in PHRSG-3.4 was questionable as it implied that the draining has to take place within a specified time.The revised text eliminates the words "quick-opening" and provides additional requirements for the drainage system such that condensate pooling is prevented. An Intent Interpretation was also approved for subsequent publication to clarify the meaning of the word"quick-opening".

Appendix I Revision Mandatory Appendix I - "Submittal of Technical Inquiries to the Boiler and Pressure Vessel Committee - Mandatory" has been moved to the Front Matter (after the "Foreword") of the Code Book. It shall continue to be treated as mandatory. This action is consistent with action taken for all other Code Sections with the 2011 Addenda.

A-65, A-68 Revision Paragraph renumbering and deletion of Fig. PG-32 resulted in a few incorrect references in the example problems in A-65 & A-68. They are now corrected under this item.

Subpart/Table: Part PHRSG


Subpart/Table: Mandatory Appendices


Subpart/Table: NonMandatory Appendices





A-68 Revision When Fig. PG-32 was deleted and replaced with the equation for "dmax", ( the maximum size opening with integral reinforcement ), the example in A-68, which refers to the Fig.PG-32 was not updated. This action deletes the reference to Fig. PG-32 and adds the calculation for "dmax".

A-69 Errata This errata item revises the terms" A41" and "A43" in the example problem "A-69" to correctly show "41" & "43" as subscripts to "A".

A-70 Revision In the example problem in A-70, the second line of the calculation of "A[sub 41]" is corrected to show "0.375 squared" multiplied by "1" (which is the value of "f[sub t2]".

A-72 Revision The concluding statement in example problem A-72 previously stated that “the actual loading does not exceed values of allowable loading”. This was incorrect.. The actual load in compression was 555 lb/in and it exceeded the allowable load which is only 523 lb/in. This revision fixes that mistake by changing the applied external load "W" from 960 lb to 860 lb in Fig.A-72 and in example A-72 such that the actual loads (both in compression and tension) are within the allowable loads per the newly calculated "L" value.

A-101 Addition A new Nonmandatory Appendix (A-101) is added to Section I to address sub-critical post weld heat treatment heating and cooling rates for Section I materials, as general guidance.

A-350 Revision The previous requirements for recording an Authorized Inspector’s National Board Commission and Endorsement on a Manufacturer’s Data Report (MDR) only when it was registered with the National Board were in conflict with the requirements of ASME QAI-1 and NB-263, Rev. 3 "Rules for National Board Inservice and New Construction Commissioned Inspectors", paras. RN-2.2 and 2.3..

This revision simplifies the requirements for the Authorized Inspector to complete the “Certificate of Shop Inspection” and the “Certificate of Field Assembly Inspection” portions of the MDR by requiring only the Inspector’s signature, National Board Commission number and Endorsement to be recorded. The need to indicate State / Provincial Commission information has been eliminated. Each Data Report Form and the Guide for completing the MDR are updated to reflect this change.

Table A-360 Revision The latest edition of ASME B31.1 approved for Section I construction listed in A-360 is now ASME B31.1b-2009 addenda.

Table A-360 Revision A cautionary note (Note 4) was added in 2010 to Table A-360 against the ASME B16.25 standard to point out to the user that machining to the "C" dimension from Tables 1 and I-1 could result in wall thickness less than specified minimum wall thickness. This is because some of the pipe specifications allow more generous tolerance (for example -1%) compared to what B16.25 permits. However, it was recognized later that the words in Note 4 could imply that it was permitted to reduce the thickness below minimum wall thickness for the end preparation . Note 4 is now revised to eliminate the permissive wording "may" and indicates that this condition requires further action by the Manufacturer such as weld build-up or a simple verification that the thickness at the end preparation is equal or greater than the required thickness.

Table A-360 Revision The Section I referenced edition of ASME Performance Test Code PTC-25 "Pressure Relief Devices" is revised from "2001" to "2008".

2331-2 Revision Code Case 2331-2, "Local Thin Areas in Cylindrical Shells" was revised. The previous entry "sqrt (R[sub t])" was corrected in 4 instances to "sqrt(R x t)". Also, in Reply (b)(1)(a) Equation 3, the value "2L" was replaced by the corrected value "sqrt(R x t)". (Published in "Code Cases: Boilers and Pressure Vessels", 2010 Edition, Supplement 4.)The Code Case now agrees with Section I, Mandatory Appendix IV - "Local Thin Areas in Cylindrical Shells and Spherical Sections of Heads" which was published in the 2010 Edition to implement the original Code Case.

The revised title indicates it shall continue to be treated as mandatory.This action is consistent with action taken for all other Code Sections with the 2011 Addenda.

Numerous Paragraphs Revision ASME has replaced the Code symbols currently used in the BPV Code (S, H, U, V, etc.) with a single "ASME" Certification Mark. This change will include a new term "Certification Designator or "Designator", analogous to the replaced Code symbol stamps, which will define the area in which the Certificate Holder is certified by ASME. Numerous paragraphs and references in all Code Sections have been revised to implement the move to the single mark which becomes mandatory on January 1, 2013.

General changes include: - "Code Symbol,” or “ASME Code Symbol” becomes “Certification Mark” - “Code stamped” becomes “stamped with the Certification Mark” or "Certification Mark stamped" - “Code stamp holder” becomes “Certificate holder” - “Certificate of Authorization Holder” becomes “Certificate holder” - “Certificate of Authorization” stays the same.

See the "Executive Summary" of this Synopsis for further details.

Article 2, T-277, T-282, and T-283

Revision It was noted by a Section V Committee member that there was a possible problem with the wording of T-282.2 regarding where density checks are made when using hole-type IQIs. The Committee decided that density checks for hole-type IQIs should be made adjacent to the essential hole. Additional editorial clarifications are included in the revision.

Article 2, T-292(b) Revision Changed previous "by inclusion or reference" to "by inclusion of the information on the review form or by reference to an attached radiographic technique details sheet" to clarify the intent of requirements that the radiographic technique details must either be attached to or included in the radiographic review form.

Article 4, Appendix III, III-463

Revision (1) Revised Mandatory Appendix III, paragraph III-463 to delete the words "for nonpiping" to make it applicable to both nonpiping and piping calibration blocks and (2) inserted new paragraph titles for T-434.1.7 (III-434.1.7) and T-434.2 (III-434.2) to also make them applicable to both nonpiping and piping examinations.

Article 4, Appendix III, III-463.1

Revision Article 4, Mandatory Appendix III, III-463.1 previously only referenced the TOFD Reference Block of Figure III-434.2.1(a). III-463.1 is revised to also reference Figure III-434.2.1(b). Additionally, Figure III-434.2.1(a) was referred to as "Figure 434.2.1(a)", without the Roman numeral III. This has been corrected.

Article 4, Appenix IV, IV-410

Revision Incorporated ASTM E 2700-09 "Standard Practice for Contact Ultrasonic Testing of Welds Using Phased Arrays" into Section V Article 4 Mandatory Appendix IV-410 by reference as SE-2700. SE-2700 fills a need not previously covered by ASME, specifically it provides the framework for an operating procedure for performing weld inspections using phased arrays. SE-2700 has been incorporated into Article 23.

Article 4, Appendix VII Errata The previously published Article 4 Mandatory Appendix VI had an incorrect Roman numeral designation. "Appendix VI" has now been correctly redesignated as "Appendix VII".

Article 4, Appendix VII, Table VII-421

Revision Added "Search Unit Mechanical Fixturing Device (manufacturer and model)" as an essential variable and changed "Scanner Adhering and Guiding Mechanism" from "essential" to "nonessential variable" for scanner requirements.

Article 4, Appendix VIII Errata The previously published Article 4 Mandatory Appendix VII had an incorrect Roman numeral designation. "Appendix VII" has now been correctly redesignated as "Appendix VIII".

Article 4, Appendix VIII, Table VIII-421

Revision Added "Search Unit Mechanical Fixturing Device (manufacturer and model)" as an essential variable and changed "Scanner Adhering and Guiding Mechanism" from "essential" to "nonessential variable" for scanner requirements.

Article 4, Appendix IX Errata The previously published Article 4 Mandatory Appendix VIII had an incorrect Roman numeral designation. "Appendix VIII" has now been correctly redesignated as "Appendix IX".

Article 4, Appendix IX, IX-435

Errata The title previously shown in Article 4, Appendix VIII-435 as "Determination Blocks" has now been corrected as "Demonstration Blocks" and the heading correctly redesignated as "IX-435".

Article 4, Various Revision Added rules for examination of the nozzle weld fusion zone and adjacent parent metal from the nozzle bore, and provided for a nozzle calibration block and text additions and changes to implement this examination. Requirements of ASME Code Section III provide for the ultrasonic examination of both the weld fusion zone of certain nozzle welds and the adjacent parent metal in the nozzle next to the weld. If this examination is carried out from the vessel side, angle beams can be less effective, as some or all of the ultrasonic beam reflected from incomplete fusion or laminations in the adjacent parent metal may not be returned to the search unit. A better examination for these types of discontinuities is made from the internal surface of the nozzle with a straight beam search unit where the ultrasonic beam is perpendicular or near perpendicular to these discontinuities and is returned directly to the search unit. (1) Changes which permit straight beam examinations from the nozzle bore are stated in T-475. Paragraphs T-475.1 "Search Unit Location" and T-475.2 "Examination" were added; (2) Text changes to implement these examinations are presented in order of their appearance in Article 4; (3) Requirements for a nozzle calibration block for nozzle ID examinations are presented in a new T-434.5 "Nozzle Side Weld Fusion Zone and/or Adjacent Nozzle Parent Metal Calibration Block"; (4) Calibration block required configuration and reflectors are provided in subparagraphs of T-434.5 and in a new Fig. T-434.5.1; (5) Changes to the calibration section were incorporated a new section T-466; and, (6) The "Calibration Confirmation" section was changed to T-467.

Article 5, T-577 and Table T-522

Revision Paragraph T-577 and Table T-522 have added "post examination cleaning" as a nonessential variable to the ultrasonic examination procedure. The words are identical to those found in T-677 for liquid penetrant examination.

Article 5, T-594 Revision Article 5 did not address storage media requirements for retention of records generated by computerized ultrasonic examination techniques. New paragraph T-594 addresses those requirements.

Article 5, Appendix III-540(b)

Revision Added definition of “Search Unit Mechanical Fixturing Device” and to the list of items included in the definition of "Scan Plan".




Article 7, T-764 Revision Many users of T-764 appear confused on the applicability of "Magnetic Field Adequacy and Direction" as it relates to the various different magnetizing techniques. This revision moved the subparagraph on this topic from the end to the beginning and reformatted the entire paragraph to make it clearer as to its use. In addition, the subparagraph concerning magnetic field direction (T-764.2) was reworded and redesignated as T-764.3.

Article 8 Revision Article 8, Mandatory Appendix VII, "Eddy Current Examination for Differentiating Surface-Connected from Subsurface Flaws", provides requirements for eddy current examination to detect flaws in magnetic and non-magnetic conductive metals with eddy current surface probes to determine if flaws are open to the surface. This Appendix provides requirements for implementing the eddy current method, for the design of reference specimens and the calibration of the system, and illustrates examples of phase and amplitude responses used to determine when a flaw is surface connected.

Article 8 Revision Article 8, Mandatory Appendix VIII, "Eddy Current Examination of Nonmagnetic Heat Exchanger Tubing" provides requirements for the examination of installed nonmagnetic tubing, such as that found in a wide range of industrial applications. Previous eddy current examination requirements (in Article 8) covered nuclear steam generator tubing and the examination of new tubing using the encircling coil technique. This Appendix provides requirements for examining nonmagnetic tubing with bore side probes, which was not previously covered in Article 8.

Article 8, Appendix IV-833

Errata Previously Mandatory Appendix IV-833 referred to SE-243 "Section 7, Calibration Standards" for reference discontinuities. "SE-243", as published in Article 26, contains the subject standards in "Section 8, Reference Standards".

Article 22, SE-1144 Revision "Standard Test Method for Determining the Size of Iridium-192 Industrial Radiographic Sources" was adopted as SE-1114. No significant changes were noted from the 2003 ASTM Edition.

Foreword Revision Former Mandatory Appendix A was revised as "Submittal of Technical Inquiries to the Boiler and Pressure Vessel Committee-Mandatory " and moved to the Front Matter (after the "Foreword" just before "Personnel") of the Code Book. It shall continue to be treated as mandatory. This action is consistent with action taken for all other Code Sections with the 2011 Addenda.

Numerous Paragraphs Revision ASME has replaced the Code symbols currently used in the BPV Code (S, H, U, V, etc.) with a single "ASME" Certification Mark. This change will include a new term "Certification Designator or "Designator", analogous to the replaced Code symbol stamps, which will define the area in which the Certificate Holder is certified by ASME. Numerous paragraphs and references in all Code Sections have been revised to implement the move to the single mark, which becomes mandatory on January 1, 2013.

Examples of changes include: - "Code Symbol,” or “ASME Code Symbol” becomes “Certification Mark” - “Code stamped” becomes “stamped with the Certification Mark” or "Certification Mark stamped" - “Code stamp holder” becomes “Certificate holder” - “Certificate of Authorization Holder” becomes “Certificate holder” - “Certificate of Authorization” stays the same.

See the "Executive Summary" of this Synopsis for further details.

QW-185 Addition This is the incorporation of Code Case 2621-1 into Section IX which permits the use of diffusion welding (DFW) as a method for material joining.

QW-185 provides for procedure and performance qualification specimens for DFW welding.

Diffusion welding (DFW) is a solid-state welding process producing a weld between multiple layers of sheet or plate by the application of pressure at elevated temperature with no macroscopic deformation or relative motion of the work pieces. A solid filler metal may be inserted between the faying surfaces. This definition was added to QW/QB-492 as "welding, diffusion".

The most important aspects of this process are temperature, time at temperature, and the contact between the two faying surfaces being joined. This process has been used successfully for many years in the construction of micro-channel heat exchangers. [Note: A faying surface is defined as: In welding, that surface of a member which is in contact, or in close proximity to, another member to which is to be joined.]

Subpart/Table: Article I





QW-251.1, QW-266 Addition This is the incorporation of Code Case 2621-1 into Section IX which permits the use of diffusion welding (DFW) as a method for material joining. QW-251.1 was revised to include the new QW-266 listing of the eight (8) essential variables for qualification of DFW Welding Procedure Specifications. . There are no nonessential or supplementary essential variables.

QW-386 Addition Requirements for qualification for DFW Welding Operators have been added and refers to QW-185 for testing requirements.

QW-400, Various Revision When LBW was first introduced into the Code over two decades ago, the essential variables were intentionally made extremely restrictive until more experience could be gained with this process. A thorough reevaluation of the variables has prompted the following changes: (1) Revised the variable descriptions in QW-402.18, QW-403.3, QW-403.15, QW-404.1, QW-404.5(b), QW-404.8, QW-408.6, QW-408.12, QW-409.19, QW-409.21, QW-410.7, QW-410.14 and QW-410.21; and (2) Added new variables QW-402.25, QW-402.26, QW-410.66, QW-410.67, QW-410.68 and QW-410.69.

QW-403, QW-404, QW-407, QW-408 and QW-410

Addition This is the incorporation of Code Case 2621-1 into Section IX which permits the use of diffusion welding (DFW) as a method for material joining. The following variables were added to incorporate DFW: QW-403.28, QW-403.29, QW-404.53, QW-407.10, QW-408.25, QW-410.70, QW-410.71 and QW-410.72. All eight (8) of these variables are listed as essential in QW-266. There are no nonessential or supplementary essential variables.

QW-409 Revision (!) QW-409.26 was revised to state that the increase in heat input shall be determined by the methods of QW-409.1; (2) QW-409.29 was revised to eliminate "volume of weld metal deposited per unit length of weld" and to state that the increase in heat input shall be determined by the methods of QW-409.1

QW-409.1 Errata (1) In QW-409.1.(c)(1), the denominator entry "[in./min]" was corrected to {in. (mm)]; (2) A comma (,) was added after "SMAW" in the first sentence.

QW-409.2 and QW-520(e)

Revision Changed "pulsed transfer mode" to "pulsed spray transfer welding" for GMAW welding to reduce the confusion encountered caused by waveform shape controlled power supplies and the fact that they can be used in both short circuiting and pulsed GMAW. End users could fail to distinguish the transfer modes properly when using waveform shape controlled power supplies because of the perception that they “pulse.”

QW-420 Revision Clarified QW-420 to explain that an unlisted base metal with the same UNS Number as a base metal listed in QW/QB-422 may for the purposes of procedure qualification be considered as assigned the same P-Number and the same tensile strength though the base metal is not listed in QW/QB-422

QW-420 Errata A new 7th paragraph was added to QW-420 explaining the addition of "ISO/TR 15608 Group Numbers" to QW/QB-422. The ISO 15608 Group column was added to QW/QB-422 in the Section IX 2010 Edition as a convenience and for information only and not as a basis for establishing the range of base metals qualified for either procedure or performance qualifciation .The explanatory paragraph was approved in 2007 but had been missed in the publication of 2010 Edition.

QW-420.2 Revision Changes in the 2009 Addenda deleted all references to S-Numbers. Unfortunately, a very useful portion of QW-420.2 that addressed the assignment of [what was then] S-Numbers to ASTM materials was lost. This revision restores that provision but embraces the "P-Number-only philosophy". Restoring this paragraph also agrees with the new wording added in QW-420 which states unlisted base metals with UNS numbers corresponding to QW/QB-422 listed base metals have the same P-Number. Additionally, the specified minimum tensile strength of the listed base metal can be applied to the unlisted base metal for the purpose of welding procedure qualification.

QW-432 Addition Three new classifications from SFA-5.14/SFA-5.14M have been added to F-No. 43: ERNiCr-7, ERNiCrFe-13 and ERNiCrMo-22.

QW-462.10 Revision Table QW-462.10(c) was added to provide shear strength values for spot and projection welds of titanium alloys (P-No. 5X). Previous QW-462.10 and QW-462.11 were renumbered as QW-462.10(a) and QW-462.10(b), respectively.

QW-466.1 Revision The SI (metric) values for test jig dimensions were corrected to whole millimeter units and made more rational.

QW/QB-422 Errata Previous specification line entry "B-653" has been corrected to "SB-653".QW/QB-422 Errata The following items were corrected in QW/QB-422:

SA-268 - The data line for UNS "S43035" was moved to after the line for "S43000"; SA-299 "Gr. A" - The "Group. No." was corrected from "3" to "2"; A 633 - "Product Forms" information for UNS "K12000" and "K12037", Minimum Spec. Tensile 65 (450), was corrected to read "up to 4 in., incl."; SA-790 UNS "S32205" - "Product Form" information corrected from "welded pipe" to "seamless and welded pipe"; SA-815 UNS "S32205" - "Product Form" corrected from "welded pipe" to "fittings". SA-1010 - Data lines "Nominal Compositions" corrected from "CR" to "Cr"; SA/EN 10028-2 Grade "P295GH" - "ISO 15608 Group" corrected from "1.1" to "1.2" and "Thickness Limits" of "Product Form" were corrected; SA/EN 10028-2 Grade "P335GH" and SA/EN 10028-3 - "Thickness Limits" of "Product Form" were corrected; SA/EN 10028-7 - "ISO 15608 Group" corrected from "..." to "8.1"; SA/EN 10216-2 Grade "10CrMo9-10" - "Nominal Composition" corrected from "2 1/2 Cr" to "2.25 Cr"; SB-169 - "Thickness Limits" on 2nd and 3rd lines of "Product Form" were corrected; SB-956 - "Welding P-No." on 2nd line corrected from "340" to "34".

QW/QB-422 Errata (1) SA-299 Gr. A - The "Welding P-No." was corrected from "3" to "2"; (2) SA-790 UNS S32205 - "Product Form" was corrected from "welded pipe" to "seamless and welded pipe".

QW/QB-422 and Appendix D

Revision The following base material reassignments were made: (1) SA-213 T91, A-217 C12A A-356 12A from "P-No. 5B Gr. 2" to "P-No. 15E Gr. 1"; (2) UNS for A-356 12A to "J84090; (3) Type or Grade from CR Cl 2 for A-691 to "91"; and (4) A-691 from "P-No. 5" to "P-No. 15E Gr. 1" in Appendix D.


Revision As a result of the incorporation of Code Case 2498 (Section VIII, Div. 1), SA/EN 10028-2 Grades P235GH and P265GH have been incorporated into QW/QB-422 and Appendix D as P-No. 1 Group 1 (Brazing P-No. 101) materials.


Revision ASTM has re-assigned N08904 from specification SB-674 to SA-249. This alloy is moving to the ferrous specifications from the non-ferrous speciifications because the predominant element in the alloy is iron under present ISO and UNS definitions. QW/QB-422 and Appendix D have incorporated SA-249 N08904 as P-No. 45 (Brazing P-No. 111). SB-674, N08904 has not been deleted from the nonferrous section of QW/QB-422 and Appendix D.


Revision Duplex Stainless Steel Alloy S32750 Bar was added to QW/QB-422 and Appendix D as P-No. 10H Group 1 (Brazing P-No. 102) material


Revision Code Case 2196-1 (Section VIII, Div. 1) has been incorporated. SA-213 TP347LN and SA-312 TP347LN have been added to QW/QB-422 and Appendix D as P-No. 8 Group 1 (Brazing P-No. 102)





Revision Revised QW/QB-422 and Appendix D to add S32101 for seamless and welded pipe and tube to SA/A 789 and SA/A 790; plate sheet and strip to SA/A 240; bar to SA/A 479; and fittings to SA/A 815. These materials are listed under P-No. 10H Gr. 1 (Brazing P-No. 102). NOTE: IN TABLE QW/QB-422, WITH THE EXCEPTION OF SA/A 815, THE STRENGTH LEVEL THICKNESS SPLITS WERE REVERSED - THE THICKER MATERIAL IS ACTUALLY WEAKER. FOR OFFICIAL ACKNOWLEDGEMENT OF THIS ERROR, SEE ASME'S WEB SITE:http://cstools.asme.org/csconnect/CommitteePages.cfm?Committee=N20120000&CommitteeErrata=yes .


Revision QW/QB-422 and Appendix D were revised to add three casting materials: SA-995 (J93380 [Grade CD3MWCun] and J99205 [Grade CD3MN]) and A890 (J99205 [Grade CD3MN]) as P-No. 10H Gr. 1 (Brazing P-No. 102).


Revision Grades E250 A, E250 B, and E250 C were added as P-No. 1 Group 1 (Brazing P-No. 101). The material is an Indian Standard for hot rolled, low, medium and high tensile strength steel that has been incorporated into the Code

QW/QB-492 Revision The definition of "machine welding" (welding, machine) was revised to delete the word "manually" as a means of making adjustments, as adjustments can be made by other methods, e.g., electronic. It also removes the words "visual observation" and replaces them with "changes" since there are other means, e.g., sound, meters, etc., by which the operator may recognize the need to make adjustments.

QW/QB-492 Addition As a result of the incorporation of Code Case 2621-1 into Section IX which permits the use of diffusion welding (DFW) as a method for material joining, the following definition was added to QW/QB-492 as "welding, diffusion (DFW)": Diffusion welding (DFW) is a solid-state welding process producing a weld between multiple layers of sheet or plate by the application of pressure at elevated temperature with no macroscopic deformation or relative motion of the work pieces. A solid filler metal may be inserted between the faying surfaces. [Note: A faying surface is defined as: In welding, that surface of a member which is in contact, or in close proximity to, another member to which is to be joined.]

Appendix A Revision Mandatory Appendix A - "Submittal of Technical Inquiries to the Boiler and Pressure Vessel Committee " has been revised and moved to the Front Matter (after the "Foreword") of the Code Book. It shall continue to be treated as mandatory. This action is consistent with action taken for all other Code Sections with the 2011 Addenda.

Appendix D Errata (1) Deleted two instances of "SA-268 TP430Ti" under P-No. 7 Grp. 2; (2) Corrected SA-182, one instance of Grp. "F316" to "F316N".

2653 Addition Code Case 2653 "F-No. Grouping for 63Ni-22-Mo-1Cr Alloy (UNS N10362) Filler Metal" was approved. The subject filler metal is assigned to F-No. 43. The Code Case was published in "Code Cases: Boilers and Pressure Vessels", 2010 Edition, Supplement 3.

2660 Addition Code Case 2660 "F-No. Grouping for 57Ni-30Cr-9Fe-1.8Nb (UNS N06043)" was approved. The subject filler metal is assigned to F-No. 43. The Code Case was published in "Code Cases: Boilers and Pressure Vessels", 2010 Edition, Supplement 3.
