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 You may also notice that Footnotes have been replaced by Endnotes in the following Code Sections: I; III, Division 1 Subsections NCA, NB, NC, ND, NG and NH; IV; X, XI and XII.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 The superseded version of the Code Case shall not be used.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 CTs 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. If you need further clarification, please contact your Inspector, Supervisor, or the Codes & Standards Staff. Thomas P. Pastor, P.E.

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, ASMEs 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 ASMEs 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 ASMEs 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 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 1100F/593C. This addition incorporates Code Case 2196-1. Added SA-451 J92800 (CPF3M) and J92900 (CPF8M) for Section VIII, Division 1 use to 800F/427C. This addition incorporates Code Case 2456. 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.




E-5

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 VIII, Division 1 Introduction Table U-3 Reference Standards This action concerns updating the reference standards listed in Table U-3. The Committee routinely monitors revisions to ASME and other reference standards, and when appropriate adopts the latest Edition of a reference standard. However one major change this year is the switch to listing "Latest Edition" instead of a specific Year Edition for many ASME dimensional standards, such as standards for screw and pipe threads (e.g. ASME B1.1 or ASME B1.20.1) or standard ASTM test methods, such as ASTM D56. However by adopting "Latest Edition" for many dimensional standards, a code user may wonder how they determine what the "Latest Edition" is. For ASME standards, the easiest way to determine this is to search for that standard on their website at www.ASME.org. For other standards such as ASTM, you can similarly search their website to determine the latest edition at www.ASTM.org. ASME is currently working on a project to develop and maintain a master list of all reference standards from the 12 boiler and pressure vessel code sections, and to publish this list on their website. This project has only just begun, and you can expect to see this information published around the same time as the 2013 Edition.

UG-11 Prefabricated or Preformed Pressure Parts Furnished Without a Certification Mark This action involves the complete rewrite of paragraph UG-11 dealing with prefabricated or preformed pressure parts, either welded or non-welded. Examples of prefabricated or preformed pressure parts include common items such as flanges supplied to an ASME standard such as B16.5 or B16.47, or parts made to a manufacturer's standard or other product standard [e.g. MSS]. Aside from the restructuring of this paragraph, there have been significant clarifications made concerning the intent of certain requirements in UG-11. These clarifications in some cases may be viewed as new requirements. In addition rules are now provided which permits a Manufacturer (Certificate Holder) to produce parts to their own internal standard in accordance with UG-11 requirements. Below is a summary of the most significant "clarifications" that result from these actions. Note that these revised rules for prefabricated or preformed pressure parts have also been published in 3.2.8. of Division 2 and KM-102 of Division 3. UG-11(a) - Introductory paragraph, essentially unchanged from the opening paragraph of UG-11. UG-11(b) - Contains the rules for cast, forged, rolled or die formed nonstandard pressure parts that are supplied as material. Essentially unchanged from 2010 Edition. UG-11(c) - Contains the rules for cast, forged, rolled, or die formed standard pressure parts that comply with ASME product standard, either welded or non-welded. These requirements were originally located in paragraph UG-11(a). This rewritten paragraph addresses both welded and non-welded standard pressure parts. Emphasis has been added to the paragraph concerning parts containing welds, and the fact that these parts must fully comply with all the applicable welding requirements of Division 1. Note that welded parts, other than shells, heads and quick-actuating closures, may be fabricated by a non-certificate holder and supplied without a Partial Data Report. Additional clarifications are added concerning PWHT, volumetric examination, the design of the part and how the pressure-temperature rating is established. The vessel Manufacturer is responsible to assure that all applicable Code requirements in these areas have been fulfilled, and he must collect and make documentation available to the Inspector with regard to the material used, the pressure-temperature rating of the part, and the basis for establishing the pressure-temperature rating. UG-11(d) - Contains the rules for cast, forged, rolled, or die formed standard pressure parts that comply with a standard other than an ASME product standard, either welded or non-welded. These are essentially parts made to a manufacturers standard or some other product standard such as MSS, or could be parts that are fabricated by the vessel Manufacturer to an internal standard. The Manufacturer has the same responsibilities as called out in UG-11(c), except that if he is unable to acquire documentation that establishes the pressure-temperature rating and the basis for establishing this rating for the part, then he must perform an analysis of the pressure part in accordance with the rules of this Division [see U-2(g)]. This analysis shall be included in the documentation and shall be made available for examination by the Inspector when requested. UG-11(e) - This is a new paragraph that provides rules for the situation when the Certificate Holder elects to subcontract the fabrication of parts made to a standard other




E-7

than an ASME product standard to another company, who may or may not be a Certificate Holder. This paragraph requires the Certificate Holder's Quality Control System to provide controls over the subcontractor in terms of satisfying Code fabrication requirements. THIS IS A SIGNIFICANT REVISION AND SHOULD BE CAREFULLY REVIEWED BY MANUFACTURERS. UHX-4(d) Rules for Vapor Belt Design Design rules for distribution and vapor belts were added to UHX-4(d). Two types of vapor belts are addressed in this paragraph. The first type is a distribution and vapor belt where the shell is not continuous across the belt, and is designed using the rules of UHX-17 and Appendix 5. The second type is a distribution and vapor belt where the shell is continuous across the belt, in which case it shall be designed in accordance with the rules for a Type 1 jacket in Appendix 9. The difference between these two cases is that in the second case, the vapor belt carries only a small percentage of the axial load within the shell.




E-8

Appendix 41 - Rules for the Design of Electric Immersion Heater Element Support Plates The provisions of Case 2651 dealing with design rules for electric immersion heater element support plates have now been incorporated into Mandatory Appendix 41. Flanged electric immersion heaters consist of tubular electric heating elements typically mounted in multiple penetrations in ASME B16.5 blind flanges. Under the current Code rules and interpretations, a flanged electric immersion heater element support plate is not considered a tubesheet but rather an unstayed flat head or cover. Therefore, the rules in Part UHX are not applicable and the cover thickness requirements are calculated using the formulas and rules in UG-34 and UG-39. For multiple penetrations, the rules in UG-39(d)(2) require the value under the square root sign in formula UG-34 (c)(2), Formula (2) to be doubled for both operating and bolting calculations. This causes the thickness to be unnecessarily greater than that computed using the Part UHX methodology. Appendix 41 now contains special rules for the design of immersion heater element support plates, based upon the rules in UHX-12 for U-tube tubesheets. These rules produce a support plate that is thinner than would be attained using the rules of UG-34 and UG-39. Code Case 2695 Case to Permit use of Section VIII, Division 2 Part 4 rules for Section VIII, Division 1 Vessel This is a significant Code Case which permits a Section VIII, Division 1 Certificate Holder to use the Part 4 [Design by Rule] section of Section VIII, Division 2 to design a pressure vessel or part. This is the first step in a long-term project initiated by the Section VIII Committee called "Common Rules". The goal of this overall project is twofold: (1) to ultimately maintain rules that are common to both Divisions 1, 2 and 3 in one location, which will be Division 2; and (2) to allow the use of the more modern, advanced design rules from Division 2 by Division 1 Certificate Holders. Some of the benefits and features from using this Code Case are:

1. The Division 2 rules will in most cases produce formed heads that are significantly thinner than required by Division 1.

2. The Division 2 opening reinforcement rules require much less reinforcement than the Division 1 rules and may avoid having to use a repad.

3. The cone-to-cylinder rules provide a more accurate solution to the problem and may avoid having to add a stiffener.

4. A certified Users Design Specification is not required. 5. The design calculations do not have to be certified by a Professional Engineer or

equivalent.




E-9

However, not all of Division 2 is permitted by the use of this Code Case: 1. Of course, Division 1 tensile allowable stresses (Section II, Part D, Tables 1A and

1B) are used rather than Division 2 tensile allowable stresses (Section II, Part D, Tables 5A and 5B).

2. If the thickness of a shell section or formed head is determined using Division 2 rules, then other features on that part (such as nozzle reinforcement) would have to use the Division 2 rules.

3. Weld joint details for the part that is being designed per Division 2 rules must be per Division 2, Part 4 4.2. For example, Division 1s Types 4, 5 and 6 fillet-weld lap joints; and flat head and nozzle double-fillet welds are not permitted.

4. The fabrication tolerances of Division 2, Parts 4 4.3 and 4.4 shall be satisfied. Also, for those situations where Division 2, Part 4 does not have rules, where Division 2 would normally permit the use of Part 5 Design by Analysis, this Case would not permit the direct use of Division 2, Part 5. If there are no Division 2, Part 4 rules, the Manufacturer has to go back to Division 1. If there are rules in Division 1, the Manufacturer is required to follow those rules. If there are no rules in Division 1, U-2(g) could be invoked. The analytical, administrative and quality control requirements in Division 2, Part 5 (again, except for the allowable stresses) should be considered for any U-2(g) analysis. Section VIII, Division 2 Part 4.5 Opening Reinforcement Rules Welding Research Council Bulletin WRC 529 contains background material on the opening reinforcement rules based on pressure-area principles and used in Division 2. During the preparation of this Bulletin, several errors, including improper coverage of set-on nozzles, were identified. These revisions to Part 4.5 bring the rules in alignment with WRC Bulletin 529. Significant changes have been made to clarify the rules in the following areas:

for set-in versus set-on nozzles calculation of the area "A2" for variable thickness nozzles consistency in the determination of the pressure area for all nozzle geometries correction of the pressure area calculation for radial nozzles in conical shells modifications to the limits of reinforcement for radial nozzles in spheres/formed

heads consolidation of design rules for hillside and perpendicular nozzles in formed

heads the addition of a pressure thrust load check on weld strength

Nomenclature and Figures have also been updated to assist the user in the correct application of the nozzle design rules.




E-10

Note that a complete, 400-page examples manual has been published for Division 2 [ASME PTB-3-2010 - Section VIII-Division 2 Example Problem Manual]. Copies of this examples manual can be purchased from ASME at the following website: http://www.asme.org/products/codes---standards/asme-section-viii-division-2-example-problem-manua 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 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.




E-11

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 VIII Pressure VesselsHSB Code Services

Tuesday, November 22, 2011 Page 1

Foreword Revision "Submittal of Technical Inquiries to the Boiler and Pressure Vessel Committee" has been moved to just before the listing of "Personnel" in the Front Matter with minor revisions.The title indicates it shall 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 recently used in the BPV Code (S, H, U, V, etc.) with a single "ASME" Certification Mark. References in the "Foreword" and "Statements of Policy" have been revised to implement the move to the single 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.

Typical changes include: - "Code Symbol, or ASME Code Symbol becomes Certification Mark - Code stamped becomes stamped with the Certification Mark or "Certification Marked stamped" - Code stamp holder becomes Certificate holder - Certificate of Authorization Holder becomes Certificate holder. - Previous Code Symbol Stamps are now referred to as "Certification Designators".

Foreword Revision Previous Mandatory Appendix I "Submittal of Technical Inquiries to the Boiler and Pressure Vessel Committee" has been moved to the Front Matter (after the Foreword, pages xviii - xvix) with minor revisions. 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 2, Appendices VIII-293 and IX-293

Revision Requirements were added to Article 2 Mandatory Appendix VIII-293 and Mandatory Appendix IX -293 that storage media for digital images must be capable of securely retaining the data for the period specified in the referencing Code Section.

Article 4, T-423.2 Revision The text was modified to clarify terminology related to dual probes.Article 4, T-434 Revision (1) T-434.2.1 and T-434.3 were revised to address both beam angle(s) and distance range(s)

when determining the adequate size and reflector locations of the calibration block; (2) T-434.3 included an editorial change of "within" to "".

Article 4, Fig. T-434.2.1 Errata An asterisk ("*") was added to the "3/4 T" location dimension to indicate that the "1/2 T" dimension is the minimum dimension.

Article 4, T-477 and Table T-421

Revision Paragraph T-477 and Table T-421 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.

Code Book: V

Part: Subpart/Table: Foreword


Subpart/Table: Subsection A





Article 4, T-494 Revision Article 4 did not address storage media requirements for retention of records generated by computerized ultrasonic examination techniques. New paragraph T-494 addresses those requirements.

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.

Article 23, SA-609 Revision "Standard Practice for Castings, Carbon, Low-Alloy, and Martensitic Stainless Steel, Ultrasonic Examination Thereof" was adopted as SA-609/609M. No significant changes from the previous 1991 (R2002) ASTM Edition were noted.

Article 23, SA-745 Revision "Standard Practice for Ultrasonic Examination of Austenitic Steel Forgings" was adopted as SA-745/745M. No significant changes were noted from the 1994 (R2003) ASTM Edition..

Article 23, SE-114 Revision Section V only refers to SE-114 "Ultrasonic Pulse-Echo Straight-Beam Examination by the Contact Method" (ASTM E114-95) as a referenced document in SB-548. It was decided to delete it from the Code Book.

Article 23, SE-213 Revision ASTM E 213-09 "Standard Practice for Ultrasonic Testing of Metal Pipe and Tubing" was adopted as SE-213. No significant changes from the 2004 ASTM Edition were noted.

Article 23, SE-2491 Revision ASTM E 2491-08 "Standard Guide for Evaluating Performance Characteristics of Phased-Array Ultrasonic Testing Instruments and Systems" was adopted as SE-2491. Only changes of note from the 2006 ASTM Edition were: (1) an enhancement of the definition for "angle corrected gain (ACG)" and (2) revisions to Fig. A2.1- "Beam Steering Assessment Block".

Article 23, SE-2700 Revision "Standard Practice for Contact Ultrasonic Testing of Welds Using Phased Arrays" was adopted 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.

Subpart/Table: Subsection B





Article 24, SD-516 Revision "Standard Test Method for Sulfate Ion in Water" was adopted as current SD-516. No significant changes were noted from the previous 2002 ASTM Edition..

Article 24, SD-1552 Revision SD-1552, "Standard Test Method for Sulfur in Petroleum Products (High-Temperature Method)", had been adopted in Article 24 as it was referenced in Article 6 (Liquid Penetrant Examination). Due to revision of Article 6 that resulted in deleting the reference, there is no need to maintain SD-1552.

Article 24, SE-165 Revision "Standard Practice for Liquid Penetrant Examination for General Industry" has been adopted as SE-165 replacing ASTM E 165-02 "Standard Test Method for Liquid Penetrant Examination". Footnotes were deleted from the ASTM document upon incorporation in Section V. No other significant changes were noted.

Article 24, SE-243 Revision "Standard Practice for Electromagnetic (Eddy-Current) Examination of Copper and Copper-Alloy Tubes", was adopted as SE-243. No significant changes were noted from the 1997(R2004) ASTM Edition.

Article 25, SE-709 Revision Adopted ASTM E 709-08, "Standard Guide for Magnetic Particle Testing", as SE-709. Notable changes from the replaced 2001 Edition of E 709 include the revised title from "Standard Guide for Magnetic Particle Examination" and the deletion of the Table of Contents.

Article 29, SE-976 Revision "Standard Guide for Determining the Reproducibility of Acoustic Emission Sensor Response", was adopted as SE-976. There were no significant revisions to the previous (2005) version.

Article 29, SE-1419 Revision "Standard Practice for Examination of Seamless, Gas-Filled, Pressure Vessels Using Acoustic Emission" was adopted as SE-1419. Section 9 added that electronic evaluation of the signal processor should be performed monthly and refers the reader to an accepted procedure. No other changes of any significance were noted from the 2002b ASTM Edition.

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

Subpart/Table:





Foreword Revision Previous Mandatory Appendix 16 - "Submittal of Technical Inquiries to the Boiler and Pressure Vessel Committee" has been moved to the Front Matter (after the Foreword, pages xxx - xxxi) with minor revisions. 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 is phasing out separate stamps (such as the U) for each Code with an accreditation program and moving to a single mark for all codes. The reason for doing this is that presently ASME must register each of their 28 stamps in hundreds of 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. In the case of Section VIII, Division 1 the Designator that will appear on the nameplate directly under the Certification Mark will be "U" , "UM", "UV" or "UD". The net result is that in dozens of places throughout Division 1, the phrases "Code Symbol" and "ASME Code Symbol" were replaced with "Certification Mark".

THERE ARE SEVERAL INSTANCES WHERE THIS JOB IS NOT COMPLETE. FOR EXAMPLE, IN A FEW PLACES "CODE SYMBOL" SHOULD BE REPLACED WITH "CERTIFICATION MARK".


Table U-3 Revision This action concerns updating the reference standards listed in Table U-3. The Committee routinely monitors revisions to ASME and other reference standards, and when appropriate adopts the latest Edition of a reference standard. However one major change this year is the switch to listing "Latest Edition" instead of a specific Year for many ASME dimensional standards, such as standards for screw and pipe threads (e.g. ASME B1.1 or ASME B1.20.1) or standard ASTM test methods, such as ASTM D56 . However by adopting "Latest Edition" for many dimensional standards, a code user may wonder how they determine what the "Latest Edition" is. For ASME standards, the easiest way to determine this is to search for that standard on their website at www.ASME.org., For other standards such as ASTM, you can similarly search their website to determine the latest edition at www.ASTM.org. Below is a summary of some of the more commonly used ASME standards and the changes that were made to the acceptable edition: ASME B. 16.1 cast-iron type flanges and flange fittings : 1998 ----> 2005 ASME B16.5 type flanges and flange fittings: 2003 (2) ---> 2009(2) ASME B16.9, B16.11, B16.15, B16.20 changed to Latest Edition ASME B16.47 Large diameter steel flanges: 1996----> 2006

Table U-3 Revision The 2008 Edition of ASME Performance Test Code PTC 25, "Pressure Relief Devices", was adopted. The previous referenced edition was 2001.

Table U-3 Revision "Standard Guide for Preparation of Metallographic Specimens", ASTM E3, was added to Table U-3. This reference is used by Appendix 42, dealing with diffusion bonding.

Code Book: VIII-1

Part: Subpart/Table: Foreword


Subpart/Table: Introduction





U-5 Addition In the process of revising the Foreword, one of ASME's goals is to remove any language that establishes mandatory requirements. One of the examples concerns tolerances. The fifth paragraph from the Foreword which deals with tolerances was relocated to new paragraph U-5 in the "Introduction". Note the Foreword still contains the 5th paragraph dealing with tolerances; this and other "mandatory" requirements will be removed when a new re-write of the Foreword is published in a future edition.

Fig. UG-34(g), Sketch (g) Revision In Figure UG-34 Sketch (g), in the definition for t[sub w], the term "1.2t [sub s]" was corrected to "1.25t [sub s]".

Numerous Paragraphs Revision ASME is phasing out separate stamps (such as the U) for each Code with an accreditation program and moving to a single mark for all codes. The reason for doing this is that presently ASME must register each of their 28 stamps in hundreds of 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. In the case of Section VIII, Division 1 the Designator that will appear on the nameplate directly under the Certification Mark will be "U" , "UM", "UV" or "UD". The net result is that in dozens of places throughout Division 1, the phrases "Code Symbol" and "ASME Code Symbol" were replaced with "Certification Mark".

In addition, the following substitutions were also made throughout the book: (a) Revised "Code stamped" to read "stamped with the Certification Mark" or "Certification Marked stamped"; (b) Revised "Code stamp holder" to read "Certificate holder"; (c) Revised "Certificate of Authorization Holder" to read "Certificate holder"; (d) "U Certificate of Authorization" to read "Certificate of Authorization with the U Designator"; (e) "U Stamp" to read "Certification Marked with the U Designator"; (f) Revised "Code UV Symbol" or Code UD Symbol" to read "Certification Mark with the UV Designator" or "Certification Mark with the UD Designator"; (g) Revised "UM vessels" to read "vessels bearing the UM Designator"; (h) Revised "UM Stamp" to read "Certification Marked with the UM Designator" (g) Fig. UG-118 revised to reflect new Certification Mark.

THERE ARE SEVERAL INSTANCES WHERE THIS JOB IS NOT COMPLETE. FOR EXAMPLE, "CODE SYMBOL" STILL EXISTS IN A FEW PLACES IN THE CODE WHERE IT SHOULD SAY "CERTIFICATION MARK".


Subpart/Table: Part UG





UG-11 Revision This action involves the complete rewrite of paragraph UG-11 dealing with prefabricated or preformed pressure parts. Examples of prefabricated or preformed pressure parts include common items such as flanges supplied to an ASME standard such as B16.5 or B16.47, or parts made to a manufacturer's standard or other product standard [e.g. MSS]. Aside from the restructuring of this paragraph, there have been significant clarifications made concerning the intent of certain requirements in UG-11. These clarifications in some cases may be viewed as new requirements. Below is a summary of the most significant "clarifications" that result from these actions:

UG-11(a) - Introductory paragraph, essentially unchanged from the opening paragraph of UG-11. UG-11(b) - Contains the rules for cast, forged, rolled or die formed nonstandard pressure parts that are supplied as material. Essentially unchanged from 2010 Edition. UG-11(c) - Contains the rules for cast, forged, rolled, or die formed standard pressure parts that comply with ASME product standard, either welded or non-welded. These requirements were originally located in paragraph UG-11(a). The second change is that this rewritten paragraph addresses both welded and non-welded standard pressure parts. Emphasis has been added to the paragraph concerning parts containing welds, and the fact that these parts must fully comply with all the applicable welding requirements of Division 1. Additional clarifications are added concerning PWHT, volumetric examination, the design of the part and how the pressure-temperature rating is established. The vessel Manufacturer is responsible to assure that all applicable Code requirements in these areas have been fulfilled, and he must collect and make documentation available to the Inspector with regard to the material used, the pressure-temperature rating of the part, and the basis for establishing the pressure-temperature rating. UG-11(d) - Contains the rules for cast, forged, rolled, or die formed standard pressure parts that comply with a standard other than an ASME product standard, either welded or non-welded. These are essentially parts made to a manufacturer's standard or some other product standard such as MSS, or could be parts that are fabricated by the vessel Manufacturer to an internal standard. The Manufacturer has the same responsibilities as called out in UG-11(c), except that if he is unable to acquire documentation that establishes the pressure-temperature rating and the basis for establishing this rating for the part, then he must perform an analysis of the pressure part in accordance with the rules of this Division [see U-2(g)]. This analysis shall be included in the documentation and shall be made available for examination by the Inspector when requested. UG-11(e) - This is a new paragraph that provides rules for the situation when the Certificate Holder elects to subcontract the fabrication of parts made to a standard other than an ASME product standard to another company, who may or may not be a Certificate Holder. This paragraph requires the Certificate Holder's Quality Control System to provide controls over the subcontractor in terms of satisfying Code fabrication requirements.

THIS IS A SIGNIFICANT REVISION AND SHOULD BE CAREFULLY REVIEWED BY MANUFACTURERS.




UG-19(a), UG-116(j), UG-120(b)

Revision These revisions address marking requirements and Data Report rules for combination units, such as shell and tube heat exchangers or jacketed vessels. In some cases one chamber of a multichambered vessel may be outside the scope of the standard. For example one side of a shell and tube heat exchanger that may be exempt per the water exemption in U-1(c)(2)(f). But in this situation the common elements, the tubesheet and tubes, must be described on the Data Report. Below is a summary of the revisions to the affected paragraphs:

UG-19(a) - in the last sentence, the phrase "Only the parts of chambers" was changed to "Only the chambers". UG-116(j)(1) - The paragraph was clarified to state that only chambers included within the scope of this Division need to be marked. The marking shall include the name of each chamber and its corresponding data. UG-116(j)(2) - This paragraph addresses the option of marking information related to chambers that are outside the scope of this Division on the combination unit. These markings shall not be included in the markings covered by the ASME Certification Mark. Note that this paragraph replaces UG-116(k), and UG-116(l) is now renumbered to UG-116(k). UG-120(b) - Revised the rules for describing combination units on Data Reports to be consistent with UG-116(j). This means that for common elements adjacent to a chamber not included within the scope of this Division, the common element design conditions from that chamber must be recorded on the Data Report. It is also recommended that those chambers not included within the scope of this Division be described in the "Remarks" section of the Data Report.

UG-20(a) Revision A warning note was added to the end of paragraph UG-20(a) concerning the use of certain fabrication details given in Division 1 for elevated temperature operation. The Note recommends that Manufacturers refer to WRC Bulletin 470 Recommendations for Design of Vessels for Elevated Temperature Service. With respect to Division 1, elevated temperature service occurs when the allowable stresses in Section II, Part D are based on time-dependent properties.

UG-32(b) Revision UG-32(b) requires increasing an unstayed ellipsoidal or torispherical head thickness by dividing the head thickness by the joint efficiency of the Category B or C weld joining the head to the shell. With the changes to UW-11(a)(5)(b) and UW-12(d) in the 1987/88 Addenda requiring spot radiography of Category B or C butt welds joining the head to the shell, there is no technical basis to increase the head thickness by dividing the head thickness by the joint efficiency of the Category B or C weld joining the head to the shell. For this reason the paragraph was deleted. Note that the paragraph number remains and the text replaced with "DELETED", so as not to disrupt the remaining paragraph numbers in UG-32.

UG-34(c)(2) Errata In subparagraph UG-34(c)(2) the references to Formulas (3) and (4) were corrected to Formulas (4) and (5), respectively.

UG-39(a) Revision A sentence was added to UG-39(a) stating that electric immersion heater support plates may be designed in accordance with the rules of UG-39 or Mandatory Appendix 41. Please see the entry for Appendix 41 for a detailed description of the rules added to design the perforated plates utilized in flanged immersion heaters.

UG-40(b)(2) Revision UG-37(a) defines R[sub n] as the inside radius of the nozzle. Fig.UG-37.1 also shows R[aub n] as the inside radius of the nozzle. However, UG-40(b)(2) defines R[sub n] as the radius of finished opening size which is not consistent with the definition provided in UG-37(a). Radius of finished opening size is not always equal to the inside radius of the nozzle. (Refer Fig.UG-40 (j), (n) as two examples). This action makes the definition of R[sub n] in UG-40(b)(2) consistent with UG-37(a).

UG-40(e) Revision As part of the action related to the revisions to UG-11, the reference to "UG-44(i)" in Paragraph UG-40(e) was corrected to "UG-44(j)".

UG-44(a) Revision ASME B16.1,"Gray Iron Pipe Flanges and Flanged Fittings", was added to the list of flange and pipe fitting standards that are acceptable for use in Division 1. This standard was already listed in Table U-3, UCI-35 and UCD-(b)(3). As a result of this addition, the remaining paragraphs of UG-44 were renumbered.

UG-90(c)(1)(n) Revision As part of the revision to the definition for "acceptance by Inspector" in Appendix 3, the statement that, by this acceptance, an Inspector does not assume any responsibilities that belong to the Manufacturer, was moved to UG-90(c)(1)(n).




UG-93(a)(1), UG-93(a)(1)(a), UG-93(a)(1)(b)

Revision UG-93(a)(1) was revised by adding additional language to emphasize that it is the vessel Manufacturer who is responsible to ensure that all requirements of the material specification, and all special requirements of this Division, that are to be fulfilled by the material manufacturer have been complied with. This is accomplished by obtaining either a certificate of compliance or material test report (MTR). The Inspector shall determine if these documents represent the material and meets the requirements of the material specification. New subparagraph UG-93(a)(1)(a) provides detailed description of the information that should be reported on the material test report or certificate of compliance. It also addresses the situation when someone other than the material manufacturer performs one or more of the specific requirements, then this shall also be documented and attached to the material documentation. Finally new subparagraph UG-93(a)(1)(b) states that the vessel Manufacturer shall receive a copy of the test report as prepared by the ORIGINATOR OF THE DATA and maintain it as part of his construction records. An example of this would be the case where one company produces the raw material and documents the heat analysis on their test report, and a second company processes material into a specific product form, and documents the finished product properties on their test report. The vessel Manufacturer must acquire a copy of both material test reports. TRANSCRIBING THE RESULTS FROM THE FIRST MANUFACTURER'S MTR ONTO THE SECOND MTR WILL NO LONGER BE ACCEPTABLE.

THIS MAY BE AN IMPORTANT CHANGE FOR SOME PLATE MATERIALS.

UG-99(b), UG-102(a) Revision Interpretation VIII-1-89-207R addressed the location of a pressure gage used for the hydrostatic test. This interpretation confirmed that the gage does not need to be installed at the highest point on the vessel, nor does it need to be installed directly to the vessel, so long as when intervening piping is used there are no intermediate valves present. These revisions to UG-99(b) and UG -102(a) incorporate the information published in Interpretation VIII-1-89-207R.

UG-99(f) Revision Vessels designed and constructed for service under high vacuum (HV) or ultra high vacuum (UHV) conditions are not routinely ASME Code stamped and certified. Vacuum vessels are specifically excluded from the scope of Section VIII, Division 1 per the provisions of U-1(c)(2)(h). As a result, HV and UHV vessels are often constructed in compliance with AWS D17.1, or some other standard. One of the barriers to using Section VIII, Division 1 for construction of these types of vessels is the pressure test rules and UG-99. Currently vessels designed for vacuum or partial vacuum service are subjected to an internal hydrostatic test at the completion of construction. However for vessels in high vacuum or ultra high vacuum service, an internal pressure test does not prove that the vessel can achieve a desired leak tightness when subjected to a vacuum, and may not be possible with the design of the sealing system for vacuum. The new rules published in UG-99(f)(2) require the pressure test to be conducted at the lowest value of specified absolute internal design pressure. In addition, a leak test shall be performed in accordance with the technical requirements of Section V, Article 10 and as specified by the user.

UG-117(f) Revision The definitions for several terms in Appendix 3 were revised to maintain consistency with similar changes in Section VIII, Division 2. With respect to the ASME Designee, the part of the original definition that described the duties of the Designee have now been moved to the fifth paragraph of UG-117(f).

UG-125(a) Revision When Case 2211 "Overpressure Protection By System Design" was incorporated into Division 1with the addition of Paragraph UG-140(a), the Committee made a revision to UG-125(a) to specifically exclude this paragraph from being applicable to unfired steam boilers. However in doing so, they inadvertently removed the sentence that still invokes Paragraphs UG-125 through UG-138 for unfired steam boilers. This revision corrects this error.




Fig. UW-21 Revision The revision shows that the dimensional requirement of the ID fillet weld is only for sizing the weld. UNFORTUNATELY, THE ARTWORK WAS NOT DONE CORRECTLY AND IT STILL SHOWS THE FILLET WELD FLUSH WITH THE FACE OF THE FLANGE - THIS WAS NOT THE INTENT; ASME HAS BEEN NOTIFIED.

Fig. UW-21 Errata In the definition of "x [sub min]", "1.4t [sub min]" was changed to "1.4t [sub n]". Also, t [sub n] indicator was added to sketch (4).

UW-3 Revision The term "Category" as used within UW-3 defines the location of a weld joint in a vessel. However not all weld joints that could possibly be used in a pressure vessel are assigned a weld joint category. Until now, this was never stated in the Code. Two sentences have now been added to the end of UW-3 providing some examples of weld joints that are not defined by a category. This would include weld joints used in the fabrication of flanged and flued or flanged only expansion joints, jacket closure-to-shell welds, and bellows-to-weld end joints.

UW-5(e), UW-27(e), UW-27(f)

Revision This action involves the incorporation of Case 2130-4, permitting the use of SA-841 Grade A, Class 1 and Grade B, Class 2 plates in Division 1 construction. A restriction on welding this material by electroslag or electrogas process was added to UW-5(e), and the original UW-5(e) paragraph renumbered to UW-5(f). A reference to UW-5(e) was also added to paragraphs UW-27(e) and UW-27(f).

UW-11(a) Revision An Inquiry to Section VIII on the subject of when full radiography applies to butt welds in nozzles and communicating chambers has led to a rewrite of paragraphs UW-11(a)(1) through (4). The majority of the changes were made to add clarity to the rules, however one technical change was introduced relative to full RT requirements for unfired steam boilers. The revisions are summarized as follows:

UW-11(a)(1) - unchanged UW-11(a)(2) - changed "vessels" to "shell and heads of vessels" to be consistent with UW-11(a)(1); also relocated the small nozzle and communicating chamber exemption to paragraph UW-11(a)(4) UW-11(a)(3) - added coverage for unfired steam boilers with design pressure not exceeding 50 psi (350 kPa) UW-11(a)(4) - the full radiography requirements for nozzles and communicating chambers was relocated from UW-11(a)(2) to this paragraph. UW-11(a)(5) - minor editorial changes UW-11(a)(6) - minor editorial changes

UW-12(f) and UW-27(a) Revision Classifies welding processes into arc, pressure and other, and fixes the cross-reference from UW-12(f).

UW-13(b)(1) Errata Changed Fig. UW-13.1 reference from sketch (j) to (i), resulting from the 2007 Edition previous deletion of sketch (d)

UW-16(f)(3)(a)(4) Revision The paragraph was revised to add "as required in (3) above." to the end to complete the thought. This corrects a supposed Errata introduced in the 1998 Edition.

UW-21 Revision An Intent Interpretation and Code revision were published to require that all B16.5 flanges (socket and slip-on) have to meet the requirements of UW-21, not just those attached to nozzle necks. This requirement now applies to B16.5 body flanges that are not designed per Appendix 2.

UW-21(b) Errata The word "fillet" was deleted because some of the sketches also use partial penetration welds as well.

UW-42 Revision Revised editorially to add headings for readability.UW-50 Revision Revised to clarify that the required NDE is to take place prior to pneumatic testing.UW-51 Addition UW-51(a)(4) was added to permit UT to be used in lieu of RT by referring to Section VIII,

Division 2, paragraph 7.5.5.

UB-30(d) Revision Tighter rules concerning the use of subcontracted welders were introduced into paragraph UW-26(d) in the 2004 Edition. These revised rules required the welding to be carried out at the location shown on the Manufacturer's Certificate of Authorization. When these revisions were introduced to UW-26(d), similar requirements for subcontracted braising in UB-30 were overlooked. This revision corrects that mistake and makes the requirements in UB-30(d) consistent with UW-26(d).

Table UCS-23 and Fig. UCS-66

Addition These are lower strength grades of carbon steels; P295GH was already permitted. Added to Fig. UCS-66 Curve B if as-rolled and Curve D if normalized.

Table UCS-23 and Fig. UCS-66

Revision The grades of SA/AS 1548 were revised to the nomenclature of AS 1548-2008. PT430NR and PT460NR were assigned to Curve B since ASME does not consider normalized rolling as equivalent to normalizing - see Fig UCS-66 Note (e)(3). PT490N and PT490NR were intentionally NOT assigned to Curve B, thus assigning it by default to Curve A since it is a higher-strength micro-alloy steel.

UCS-5(c) Revision Limits the welding on carbon and low alloy steels with > 0.35% carbon to only as specifically permitted by Part UF. This avoids the confusion as to whether there are other instances where it might be permitted, such as welding of higher-carbon nuts to pressure boundary [ref. Interpretation VIII-1-92-83]. However, the tack welding of higher-carbon nuts to higher-carbon bolts is not prohibited [ref. Interpretation VIII-1-86-29].
