Important Revisions in 2010 EditionSection 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


Significant Revisions in 2010 EditionSection 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



• 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



• 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


Significant Revisions in 2011 AddendaGeneral

• 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



• 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

U8



• 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



• 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



• 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



• 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



• 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-263

13


Significant Revisions in 2011 AddendaSection 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



• 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



• 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 2662

16



• 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



• 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) – toughness @ < -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



• 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



• 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 2621-1

• New Mandatory Appendix - electric immersion heater element support plates– Based on Part UHX for U-tubes

20


Significant Revisions in 2011 AddendaSection 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-161.1 – Specimens– Allow multiple specimens to be taken across the weld– The entire weld and heat affected zones are tested

21



• 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



• QW-300.3 – 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



• QW-409.2 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



• 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



• 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-420.2 provision was deleted in A09 when S-No.’s were deleted• Intent Interpretation

26



• QW-466.1 – test jig dimensions– Corrected the metric conversions

• QW-510 – SWPS tests– Changed radiographic/ally to volumetric/ally– Now includes ultrasonic NDE

27



• 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
