1 HSB Global Standards ASME Code Changes and Discussions ASME Code Section VIII-1 and Referencing Code Section IX Presented by: David M. Allore Field Services Manager September 21, 2011

2 Introduction Largest Authorized Inspection Agency (AIA) accredited by ASME Design Offices in France and USA Worldwide Reputation of Codes and Standards Group Leadership and largest ASME Code Committee representation among all accredited AIA s ASN Agreed Notified Body Forum Members of PED Notified Body Forums (CABF) in Brussels, Germany and UK ESPN Technical Committee (COLEN) Notified Body for the European Pressure Equipment Directive (PED) 97/23/EC Internationally Accredited by ANSI-ASQ and KAB to provide ISO 9000, ISO 13485, AS-9000, and ISO Registration Services Accredited as a recognized third-party inspection agency for all major boiler and pressure vessel codes, standards, regulations globally 2

3 Important Revisions in 2010 Edition Section VIII-1 UG-11(d) Mfr. must assure that parts furnished under the provisions of UG-11(a), (b) and (c) meet all applicable Code requirements such as UCS-79(d), UCS-85, UNF-79(a)(1), UHA-44(a) & UHT-79(a)(1) Further tightening of miscellaneous parts rules UG-36(b)(1), Appendix 1, 1-10 Revision made consistent with following Interpretation: Question: When Appendix 1-10 is used in lieu of Appendix 1-7, as allowed by paragraph UG-36(b)(1) for large openings in cylindrical or conical shells, is it the intent that the area replacement requirements of paragraph UG-37 also be satisfied? Reply: No. 3

4 Significant Revisions in 2010 Edition Section VIII-1 UG-45 Simplification of Rules Nozzle neck sizing rules of UG-45 are often misinterpreted New rules modeled after those published in VIII-2 Simpler presentation however requires an understanding of min/max rules. Min. Thickness of standard wall pipe now acquired from Table, instead of looking up in handbook 4

5 Significant Revisions in 2010 Edition Section VIII-1 UW-2(c) Use of ERW Pipe as the Shell in an Unfired Steam Boiler Current rules require all joints of Category A to be fully radiographed. Code considers ERW pipe to have a Category A joint Revision makes rules consistent with Section I (PG-9.5 & Part PEB) and the use of ERW pipe material ERW pipe may be used as the shell of a unfired steam boiler t < ½ in. Diameter shall not exceed 24 inches ( DN 600) ERW weld shall be completed using high-frequency induction (HFI) welding. 5

6 Significant Revisions in 2010 Edition Section VIII-1 Appendix 2, Bolt Spacing Correction Factor Maximum bolt spacing and a bolt spacing correction factor are being added to the flange design rules Applies to vessels in lethal service When specified by the user or designated agent 6

7 General 2011 Publication The current plan is that ASME will be publishing complete reprints (white pages) for all B&PV Code books Some books will be published with their old software and some with new software (xml) Even though it is a complete reprint, it is considered an Addenda On Data Reports, 2010 Edition and 2011 Addenda would be listed. Next publication will be the 2013 Edition No Addenda Code Cases will still be published quarterly Errata will be published on ASME website as soon as approved Special Safety Notices may be published on website 7

8 General Code Symbol Stamp phasing out separate stamps (such as the U) for each Code moving to a single mark for all codes new term: "Certification Designator or Designator defines the area in which the Certificate Holder is certified by ASME For example, for VIII-1, "U", "UV" or "UD marked on the nameplate directly under the Certification Mark Non-nuclear Code Case for 18 month transition U 8

9 General Code Construction at Location Other than that Listed on Certificate Certificate Holder may request ASME to authorize code construction at another location Intended for situations where Cert. Holder needs additional production space to handle overflow work, or perhaps access to a larger crane Cert. Holder would apply to ASME requesting permission to fabricate at additional location (temporary shop) ASME would request AIA to audit Temporary Shop and verify that it is suitable for intended construction activity Following receipt of the AIA s audit report, ASME may issue a Letter authorizing temporary use of a new shop location for a period of not longer than one year or to the time the Certificate Holder s Certificate will expire 9

10 General Temporary Shop Used by Certificate Holders (cont.) ASME accepts AIA audit report and $1,305 fee ASME will issue to the Certificate Holder a Letter Upon expiration of the letter, further extension to allow the temporary shop to continue operation will require a full ASME review prior to the expiration of the authorization No more than one temporary use Letter issued to a Certificate Holder at any one time and no more than two temporary use letters issued during a three year period 10

11 General Temporary Shop Used by Certificate Holders (cont.) If two temporary use letters are issued during the three year period they must be for different temporary shop locations (i.e., during the three year period a temporary shop address would be eligible for only (1) one-year temporary use letter). AIS must indicate in their report how the Certificate Holder s assigned AI/AIS will perform inspections at the temporary Code shop, when the temporary Code shop is located a distance greater than 200 miles from the Code shop 11

12 General Temporary Shop Used by Certificate Holders (cont.) The address, Certificate Number and expiration date of the Manufacturer to be listed on the Data Report would be that of the Certificate of Authorization, not the temporary location. The Temporary Location Letter expiration date could (but is not required to) be listed in the Remarks. This new policy does not affect work done at a temporary, intermediate field site location, where the intermediate part of that statement means a ship dock, rail yard, etc. where pieces of the pressure vessel are further assembled before being shipped to the final location. 12

13 General Data Reports All (nuclear and non-nuclear) data reports revised Established consistent National Board certification wording Current: AI may only use National Board Commission Number and endorsement when the vessel or part would be registered with the National Board. Revision: also required when the vessel will not be registered required per NB

14 Section VIII-1 UG-11 Prefabricated or Preformed Pressure Parts Applies to ASME product standards (e.g., B16.5, B16.9, etc) and manufacturer s standards Complete re-write of paragraph Paragraph restructured and greatly embellished to improve clarity and understanding of the requirements Net result is that vessel Manufacturer must be able to produce evidence that the part fully complies with all applicable Code requirements Design basis for pressure-temperature rating Welding Heat treatment 14

15 Section VIII-1 UG-32(b) head design for internal pressure UG-32(b) required 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 for the UG- 32(b) requirement UG-32(b) deleted 15

16 Section VIII-1 UG-93 and App 3 material documentation UG-93(a)(1): expanded documentation requirements for plate material App 3: revised definition of certificate of compliance, material, material supplier and Material Test Report UG-99(b) and UG-102(a) pressure tests prohibit the use of valves between vessel and pressure gage require adjustment of test pressure accounting for elevation differences between chamber and pressure gauge UG-99(f) Vacuum Service Vessels Revised pressure testing requirements for pressure vessels designed only for vacuum service Implementing Code Case

17 Section VIII-1 UG-125(a) pressure relief devices for unfired steam boilers required to meet UG-125 through UG-138 When incorporating Code Case 2211 ( Overpressure by System Design ), inadvertently excluded pressure relief devices for unfired steam boilers UW-11(a) rewrite full RT requirements Changed vessels & vessel sections or heads to the shell and heads of vessels so that all terms will be the same Separated full radiography requirements for nozzles and communicating chambers from vessels 17

18 Section VIII-1 UB-30 subcontracted brazers Made consistent with UW-26(d) permit subcontracted brazers only at the location(s) at which ASME has authorized the Manufacture to do work UHA-51(a)(4) < -320F (-196C) Added Type 308L filler metal with GTAW or GMAW UCS-5(c) carbon content limit for welding clarify the applicability of the parenthetical statement at the end to only the provisions of Part UF 18

19 Section VIII-1 Appendices 6 and 8 Documentation of MT and PT Reports Starting with A02, Articles 6 and 7 of SC V inserted more detailed documentation requirements Additions of 6-1(d) and 8-1(d) state that documentation showing that the required examinations have been performed and that the results are acceptable shall be made available to the Inspector Intent Interpretation published Appendix 10, 10-13(b)(6) Welders Qualification Records Welders Qualification Records for each welder per UW-37(f) Intent Interpretation 19

20 Section VIII-1 Appendix 35 Mass Produced Vessels clarify the involvement between Inspector and AIA of record For the inspection and quality control procedure and Quality Control System, the Manufacturer shall submit to: the AIA of record, legal jurisdiction, ASME Designee The Manufacturer shall follow the same procedure when revising the inspection and quality control procedure. New Mandatory Appendix Diffusion Bonding Incorporates Code Case New Mandatory Appendix - electric immersion heater element support plates Based on Part UHX for U-tubes 20

21 Section IX Diffusion Welding Added as a new welding process QW-185 paragraphs added QW-26X new table of variables QW-4XX new variables added QW-386 new welding operator requirements QW/QB-492 new definition added QW Specimens Allow multiple specimens to be taken across the weld The entire weld and heat affected zones are tested 21

22 Section IX QW-264 Laser Beam Welding (LBW) Deleted and added references to existing variables and added new variables Made less restrictive Will require evaluation of WPS s and PQR s 22

23 Section IX QW Simultaneous welder performance qualifications conducted by multiple contractors With a single WPS, each participating contractor must have a PQR supporting the essential variables of the WPS However, for an AWS SWPS qualified by demonstration does not have a PQR inconsistent Literal interpretation of the Code: the contractor would be excluded from participation in simultaneous performance qualifications if no PQR A SWPS adopted under the provisions of Article V is acceptable to support simultaneous performance qualifications provided the qualified range of essential variables in the SWPS agrees with those of the single WPS 23

24 Section IX QW and QW-520 Definition of GMAW Pulse Transfer Confusion caused by waveform shape controlled power supplies that can be used in both short-circuiting and pulsed GMAW might confuse the transfer modes when using waveform shape controlled power supplies because of the perception that they pulse 24

25 Section IX Table QW/QB-422 all 9Cr-1Mo-V steels assigned to the newly-created P-No. 15E Gr. 1 listing SA-213 T91, A217 C12A, and A356 12A had been omitted with the global change Table QW/QB-422 Addition of SA-249 UNS N08904 (904L) non-ferrous ferrous specifications the predominant element in the alloy is iron SB-674 N08904 will not be deleted Transition of this family of alloys 25

26 Section IX QW-420 unlisted material s P-No. Clarified that an unlisted base metal with the same UNS Number as a base metal listed in QW/QB-422 may be considered the same P- Number and the same tensile strength though the base metal is not listed in QW/QB-422 Restored coverage for ASTM materials QW provision was deleted in A09 when S-No. s were deleted Intent Interpretation 26

27 Section IX QW test jig dimensions Corrected the metric conversions QW-510 SWPS tests Changed radiographic/ally to volumetric/ally Now includes ultrasonic NDE 27

28 Section IX Definition of machine welding revised: welding, machine: welding with equipment that has controls that are manually adjusted can be adjusted by the welding operator, or adjusted under the welding operator s direction, in response to visual observation of the welding, changes in the welding conditions. The torch, gun, or electrode holder is held by a mechanical device. See also welding, automatic. adjustments can be made by other methods, e.g., electronic there are other means, e.g., sound, meters, etc., by which the operator may recognize the need to make adjustments 28
