REPORT TO PVMA ON ASME BOILER AND BOARD ON PRESSURE TECHNOLOGY MEETINGS

FOR THE 2nd QUARTER OF 2012 The following is a highlight summary of the technical and administrative items that resulted from the Boiler and Pressure Vessel Code Committee Meetings held in Nashville, TN. The items that are summarized in this Report should be of interest to PVMA members in connection with pressure vessel design, fabrication and testing activities. The ASME administrative items and other initiatives are for information on active work and are not effective until passed by the BPV Standards Committee VIII and Board on Pressure Technology Codes and Standards (BPTCS). The Standards Committee technical items are subject to approval by the BPTCS by letter ballot. ITEMS OF GENERAL INTEREST TO PVMA MEMBERS: ASME PRESSURE VESSEL AND PIPING CONFERENCE 2012 - 2013 Meetings of the ASME BPV Codes August 13 – 17: Washington, DC November 5 – 9: Phoenix, AZ February 11-15, 2013: Los Angeles, CA May 13-17, 2013: Miami, FL PVMA HIGHLIGHT ITEMS: COMMON RULES TASK GROUP:

PVMA comments on this task group’s effort were significant in causing a change in direction. Current plans call for a more gradual transition between Section VIII, Div. 1 and Div. 2. UG-16 will be revised to allow Div. 2 DBR Part 4 rules to be used in Div. 1 design with Div. 1 stress allowable.

NOTE: Code case 2695 to allow the Division 2 design by rule Part 4 to be used for Division 1 design has been approved by BPV VIII.The actual work on the common rules committee has begun. The task force has met and plans are being put in place for implementation of the code case

RECENT BPV CODE INTERPRETATIONS: Item 05-237: Section VIII, Division 1; Revise Interpretation VIII-1-95-17 Revise Interpretation VIII-1-95-17 to the following question and answer. Question (1): ERW pipe is supplied to a vessel Manufacturer by a material supplier for the shell of a pressure vessel. The heads are welded to the shell by an arc welding process. Is the ERW seam considered a Category A joint? Reply (1): No, the welded pipe or tube is a material and not a part. It is handled the same as seamless pipe as noted in paragraphs UW-12(e), and UW-12(d), but with the allowable tensile stress taken from the welded product of the stress tables. Question (2): If the Reply to Question (1) is no, does UG-116(b)(1) of Section VIII, Division require both letters "W" and "RES" to be marked on the nameplate under the code symbol stamp? Reply (2): No The revision to the interpretation is based on calling the ERW pipe a material and not a welded part. The welding of the material to make it a pipe is handled by UW-12(d) and UW-12(e) where the allowable tensile stress is reduced to account for the joint efficiency. The fact that the seam in ERW pipe cannot be located visually makes it impossible to meet the requirements of UW-9(d) for staggered seams. Since it is a material and not a welded part the qualifications of the welders and welding operation cannot be inspected and documented as required by UG-90(a)(11). To help in the clarity of Interpretation VIII-1-95-17, the language of UW-12(e) was modified and approved by VIII SGGR This record is now moving forward since VIII SGGR approval on 4/12/12. This item will be discussed at the May 2012 VIII meeting. No Action was taken in Nashville on this item @ SGGR meeting . Recent BPV Code Cases:

(NEW)Item 10-318: Section VIII, Division 1; Incorporation/Annulment of Code Case 2260-1 There are four reasons that Case 2260 should be annulled: 1. These rules have become outdated relative to the more advanced rules that are now published in Part 4.3 of VIII-2. 2. Today Section VIII-1 Certificate Holders can use the Section VIII-2 head design rules via Code Case 2695. 3. Subgroup Design of Section VIII has determined that when the more advanced head design rules of VIII-2 are used, it is necessary to also use the VIII-2 opening reinforcement rules to maintain consistency in the design. Since Case 2260 did not consider opening reinforcement within its rules, this is another reason that annulment of Case 2260 is appropriate, and Section VIII-1 Manufacturers should use Case 2695 to design thinner heads using the rules in VIII-2. 4. SGD has opened an item to consider replacing the head design rules in VIII-1 with the rules from VIII-2. Until this takes place, Case 2695 will continue to provide access to head design rules in VIII-2 for VIII-1 Certificate Holders. This item was disapproved by BPV VIII ballot 12-525 on 4/10/12. This item was reworked and approved by BPV VIII ballot 12-525RC1 on 6/28/12. BPTCS approved this item in ballot 12-1420 on 6/28/12. Code Case 2260 is included in this report as attachment #3. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition. (NEW)Item 12-46: Section VIII, Division 1; Code Case on Indicating Gage and intermediate Block Valves (pressure testing) When UG-102 was updated for the 2011 addenda of Section VIII, Div. 1 valves were prohibited between the indicating gage and the vessel during pressure testing. Without knowing, this change to the code has caused major problems for manufacturers of mass produced pressure vessels. A number of these manufacturers have specially designed test chambers that are used to hydrostatically or pneumatically test vessels in a fully enclosed, safe manner. These test chambers are sized to closely fit the vessels being pressure tested and do not allow room or sufficient visibility to adequately inspect these vessels for leaks when the test pressure is reduced to design pressure within the test chamber. The valve as depicted in the background material file of the record is

4

closed after the pressure is reduced to design pressure, the quick disconnect is broken and then the vessel is moved to a leak inspection area. This method of testing and leak inspection has been used successfully for many years by the affected manufactures. Several million vessels have been tested in this manner. This item was disapproved by SGGR VIII on 2/7/12 in ballot 12-98. Revisions were made and this item was disapproved by BPV VIII on 4/10/12 in ballot 12-537. BPV VIII approved this item on 5/8/12 in ballot 12-537RC1. BPTCS gave approval on 5/24/12 in ballot 12-1106. Code Case # 2726 has been assigned but is not formally published at this date. A letter from Gerry Eisenberg of ASME was forwarded to PVMA staff for distribution to all members. A copy of the approved language is shown in Attachment #1 to this report. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition. Item 11-860: Section VIII, Division 1; Incorporation of Code Case 2369 "Alternative Rules for Pressure Testing Vessels Utilizing a Bolted Flat Blind Flange as Removable or Remote End Closures into Appendix 35. Create para 35-7 and insert Code Case 2369 language into a new para. 35-7 Hydrostatic Testing. Annul Code Case 2369 six months after the 2013 of Section VIII, Div. 1 is published. Code Case 2369 has been in effect since 2001. Its use is mature and it is time to incorporate the language into Section VIII, Division 1, Appendix 35. This item was disapproved by SGGR VIII on 01/10/12. It was reworked and approved by SGGR VIII at the Feb. 8 meeting in Houston and submitted to BPV VIII. The item was disapproved by BPV VIII ballot 12-537 on 4/10/12. Agrement was reached and BPV VIII approval was given on 6/4/12 in ballot 12-537RC2. BPTCS approval was given on 6/28/12 in ballot 12-1420. A copy of the approved language for paragraph 35-7 is shown in Attachment #2 to this report. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition. (NEW) Item 11-2033: Section VIII, Division 1; Code Case to Allow Manufacturer’s to use up Nameplates in Inventory An action was approved under Record 07-225 to remove the use of the term "maximum allowable external working pressure (MAEWP)" in Section VIII, Divisions 1 and 2. One result of this action was some changes to the Section VIII nameplates. As it is common for high-volume Section VIII, Division 1 Manufacturers to have nameplates made in bulk and stored in inventory for future work, this proposed code case will allow them to use up nameplates in inventory for a period of 18 months following publication of the 2013 Edition of

5

Section VIII, Division 1. Note that a similar Case is not proposed for Section VIII, Division 2, since the practice of stockpiling premade nameplates is not common. This item was approved by BPV VIII ballot 12-537 on 4/10/12. BPTCS approved this item in ballot 12-1069 on 5/23/12. A copy of the approved language is shown in Attachment #4 to this report. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition. SECTION VIII TECHNICAL ITEMS (These items have been or will be submitted for ballot by the BPV VIII Standards Committee): Item 11-2185:Section VIII, Division 1; UG-20(f)(2) Paragraph UG-20(f) provides an exemption from impact testing for vessels that satisfy a number of conditions. One of these conditions is that the completed vessel shall be hydrostatically tested. This condition that vessels be hydrostatically tested prohibited manufacturers of mass-produced vessels from using this impact test exemption, since they commonly pneumatically test their vessels. In 1989, a code case [Case 2046] was approved which allowed use of the UG-20(f) impact test exemption for pneumatically tested pressure vessels. The provisions of this code case where incorporated into Appendix 35 of VIII-1 in the 2008 Addenda. This proposed revision provides a necessary link between the UG-20(f)(2) requirement and the pneumatic test provisions given in 35-6. This item was disapproved by BPV VIII on 4/10/2012 in ballot 12-537 with 5 negative votes. This item was approved by BPV VIII on recirculation ballot 12-537RC1 on 6/4/12. BPTCS approval occurred in ballot 12-1420 on 6/28/12. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition. (NEW) Item 09-741: Section VIII, Division 1; Appendix W. Section VIII, Division 2; Appendix 2-D. Revise Forms U-1, U-1A, U-2, U-2A, U-3, Table W-3 and Forms A-1, A-2 and Table 2-D.1 to add a listing for body flanges. There are several locations provided for flanges for nozzles and bolting, but not for body flanges of shells, heads and channels. This item was disapproved by BPV VIII ballot 12-537 on 4/10/12. This item was reworked and approved by BPV VIII ballot 12-537RC2 on 6/4/12. BPTCS approved this item in ballot 12-1420 on 6/28/12. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition.

(NEW) Item 09-819: Section VIII, Divisions 1 and 2; Post-forming Heat Treatment for Grade 91 Revise Division 1 paragraph UCS-79 title, revise UCS-79(d), add UCS-79(e) and (f), and Table UCS-79, in Division 1; and revise 6.1.2.3, add new paragraph 6.1.2.3(f), revise 6.1.2.4, add new Table 6.2.A, and revise Table 6.2 to be Table 6.2.B, in Division 2. In order to control the deleterious effects of cold work in Grade 91 material, and, in the future, that of other creep-strength enhanced Ferritic (CSEF) steels, rules governing when post-forming heat treatment is required have been developed and recommended by the BPV II TG on CSEF Steels. The intent of these rules is to insure that the material will have the desired creep strength following completion of all processing. At this time, the proposed rules address only Grade 91 material, the only CSEF steel grade currently incorporated for Section VIII, Divisions 1 and 2, construction. This action parallels a previous BPV I action that led to the publication of PG-20 and Table PG-20 in Section I. Also, as part of this action, and to address negatives from previous ballots, rather than have slightly different rules for calculating maximum strain or extreme fiber elongation in several locations, the equations in UCS-79(d) have been deleted and replaced with a reference to new Table UG-79, which is similar to Table 6.1 in Division 2. Table UG-79 is being added by linked item 12-237. Also, Tables UCS-79 and 6.2.A have been re-formatted to improve their clarity. To address comments received at the 02 08 2012 meeting of SG F&I, the revision to UCS-79(d) was further revised, editorially, to mimic the language in 6.1.2.3(c). This action also includes addition of new paragraph UCS-79(f) and deletion of the word, plate, from 6.1.2.3((e).Finally, the item has been further editorially revised, to change the title of UCS-79 and to correct the omissions in Tables UCS-79 and 6.2.A. This item was disapproved by BPV VIII ballot 12-537 on 4/10/12. This item was reworked and approved by BPV VIII ballot 12-537RC2 on 6/4/12. BPTCS approved this item in ballot 12-1420 on 6/28/12. A copy of the approved language is shown in Attachment #6 to this report. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition. (NEW) Item 12-237: Section VIII, Division 1; Revise UG-79, UNF-79, UHA-44, and UHT-79; and add New Table UG-79 Formulas for calculating forming strains appear in Table 6.1 of Division 2. This action creates a new Section VIII, Division 1 Table UG-79 that draws on Table 6.1 of Division 2 and deletes the forming strain/maximum fiber elongation formulas in UHA-44(a), UNF-79(a) and UHT-79(a)(1) and replaces them with a reference to new Table UG-79. This item is linked to 09-819. Item 09-819 makes the same revision to UCS-79(d) that is being made by this action to UHA-44(a), UNF-79(a), and UHT-79(a)(1). (See the Proposal File for 09-819.) The differences between new Table UG-79 in Division 1 and Table 6.1 in Division 2 are: 1. The Bouhelier formula for double-curvature parts is not being added to Division 1, Table UG-79. That action is the subject of 01-743. It was suggested,

7

during the SG F&I meeting of 02-08-2012, that if the Bouhelier formula were to be used, then the present 5% strain limit would need to be relaxed. 2. At the recommendation of BPV VIII, during the presentation for this item at the 02-09-2012 meeting, the alternative formula for strain in tube and pipe bends, which requires measurement of the thickness at the extrados of each bend, and which is now in now in both UHA-44(a) and UNF-79(a), is being deleted. No objection to this deletion was expressed at the meeting. 3. The description of the formula for heads now in UCS-79 is retained. This item was disapproved by BPV VIII ballot 12-537 on 4/10/12. This item was reworked and approved by BPV VIII ballot 12-537RC2 on 6/4/12. BPTCS approved this item in ballot 12-1420 on 6/28/12. A copy of the approved language is shown in Attachment #7 to this report. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition. (NEW) Item 11-2101: Section VIII, Division 1; Appendix-W - Form U-1A, Table W-3 Explanation: 1. Form U-1A line 5 is currently inconsistent with all the other Forms. 2. Welded austenitic stainless steel pipe and tube is made using an autogenous process such as GTAW without filler or LBW without filler, so it is neither S (seamless) nor E (electric resistance welded). See SA_312 and SA-249, for example. 3. Types 7 & 8 were added to Table UW-12 in the 2002 Addenda under BC00-629, but App W was not revised accordingly. 4. Note 24 clearly indicates what the joint efficiency means for the Category A weld [What value of E is used in UG-27(c)(1)?], but it is not so stated in Note 26 (What value of E is used in UG-27(c)(2)?]. Change Summary: Revise Form U-1A line 5 to be consistent with all the other Forms. Revise Note 23 to add a joint type of W for autogenously welded pipe and tube. Revise Note 25 to add Types 7 & 8. Revise Note 26 to add an explanation for the joint efficiency for the circumferential joint(s) of the shell This item was disapproved by BPV VIII ballot 12-537 on 4/10/12. This item was reworked and approved by BPV VIII ballot 12-537RC2 on 6/4/12. BPTCS approved this item in ballot 12-1420 on 6/28/12. A copy of the approved language is shown in Attachment #5 to this report. This item is complete and will not appear in the 3rd Quarter report. This item will be included in the 2013 edition.

SECTION XII TECHNICAL ITEMS: Section XII, Item 09-1153; Establishing Governing Code Edition and Addenda Approve a revision to Section XII to clarify the requirements for governing Code Edition. BPV Section I issued Interpretation I-01-13 to clarify governing Edition and Addenda requirements and certification rules for parts "contracted for" at a time when the Code Addenda in effect is later than the Addenda governing the manufacture of the boiler. It is the opinion of some that the effect of this interpretation was “Code rule by interpretation”. It has been suggested that the Code be revised to clarify the requirements rather than relying on interpretations. During work on this item, it became apparent that clarification was needed for establishing governing Code Edition and Addenda for new construction and field assembly as well as for parts. This item has been submitted for review of BPV XII on 3/27/12 on ballot 12-745. This ballot is due to close on 5/14/12 and will be covered in the 2nd Quarter report. Section XII, Item 09-1883; “Code Case for cold stretched vessels” In January 2008, CC 2596 was approved to allow manufacture of Section VIII, Div 1 pressure vessels. The cold stretched procedure increases the yield strength by a factor of approximately two. Allowable design stress is based on the increased yield strength. This results in a lower weight vessel. This Code Case has been modified to allow the construction of cold stretched vessels for Section XII. Background information on this technology is provided in the background file. The information shown in the background file was presented to the BPV MC prior to the approval of the CC 2596. This item was disapproved by BPV XII 12/19/2011 on ballot 11-2662. This item was approved by BPV XII on 3/30/12 in ballot 11-2662RC1. Item 10-1330: Section XII - TM 250 revision to better reflect Section VIII-1, UHA 51 impact test requirements. Update TM-250 to reflect recent changes in VIII-1 UHA-51. A Nonmandatory Appendix is added for flow chart illustration of impact test requirements as in Nonmandatory Appendix JJ in VIII-D1. Revise TM-100.1(b)(1) because of cross reference to TM-250.4(a)(1), which is deleted under this revision. This item was disapproved by BPV XII on 12/18/11 in ballot 11-2662. A recirculation ballot 11-2662RC1 approved this item on 3/30/11. BPTCS approval was given on 8/9/12 on ballot 12-1732. The attachment #4 to the 1st Quarter

9

report is still valid. This item is complete and will not appear in the 3rd Quarter report. (NEW) Item 11-418: Section XII - using design pressure as MAWP in hydrotest (TT-210(a)(1) and (b)(3) Allow the design pressure as MAWP to calculate the hydrotest pressure in TT-210(a)(1) and (b)(3) as in BPV VIII-D1 UG-99. When MAWP is not available, BPV VIII-D1 allows using design pressure to calculate the hydro/pneumatic test pressure as stated in Footnote 34 in UG-99 and UG-100). This provision is absent in Section XII. Add "The MAWP may be assumed to be the same as the design pressure when calculations are not made to determine the MAWP" in TT-210(a)(1). This item was disapproved by BPV XII on 12/18/11 in ballot 11-2662. A recirculation ballot 11-2662RC1 approved this item on 3/30/11. BPTCS approval was given on 8/9/12 on ballot 12-1732. BPTCS activities of note: Meeting of June13 thru 14, 2012 in Tampa, FL BPV VIII committee report to BPTCS provided the following update that is of interest to PVMA members: Continuing education from ASME. ASME education group has established what appear to be some helpful training courses for engineers. Many are not code related but more technical to increase your engineering knowledge. You can also use them for RPE PDH’s. Look the site over at the following URL: go.asme.org/eLearning Victor Bogosian of National Board reported. There are proposed actions at BPV I, IV, & VIII to reference QAI-1, Part 8 for qualification of Certified Individuals. National Board has completed on-line training courses supporting QAI-1 requirements for Certified Individuals for Electric Boilers (Section I)

Cast Iron Boilers (Section IV)

Cast Aluminum Boilers (Section IV)

Miniature Pressure Vessels (Section VIII)

RTP equipment The on-line course for Pressure Relieving Devices should be completed by July 1. As of May 1, 2012, the National Board has received accreditation by IACET International Association for Continuing Education and Training (CEU). NB-263 Rules for National Board Inservice and New Construction Commissioned

10

Inspectors, revision 5 was approved by the BOT, reducing the training requirement from three years to two years. The procedure becomes effective January 1, 2013. NB-426 Criteria for Acceptance of Continuing Education Courses has been adopted as an alternate to National Board training requirements in NB-263. It provides for the employer to provide training, approved by the National Board. PROPOSED NON-NUCLEAR MATERIAL CERTIFICATION PROGRAM Preliminary discussions were held at the June BPTCS Meeting on the proposed material certification program at which time it was requested that additional supporting information be made available in Elmar Upitis' report of the results of his investigation before further consideration would be given by BPTCS. Tom Pastor has briefed me on this activity, which he chairs for BPTCS, and they are not ready or in a position to make presentations at this time. BPV VIII Common Rules Project: Lou Hayden has been contracted as the Project Manager. Work on Phase 1 has begun. Phase 1 is made up of four Tasks: The next common rule meeting will take place on 8/16/2012 in Washington, DC. o Task 1: Development of a Code Case and modifications to Div 1 UG-16 to permit Div 2 DBR to be used for Div 1 construction, and the evaluation of a similar action for Div 3. An article was written by Lou Hayden and published in the ASME News Letter on the use of VIII, Div.2 DBR Part 4 for designing Div. 1 vessels. A copy of this article is attachment #8 to this report. A final copy of CC2695 is included. o Task 2: Modification of Div 2 to include vessel classes. Work is progressing on reviewing Div. 1& 2 to determine what issues exist that must be resolved to implement two classes of pressure vessel design under Div. 2. o Task 3: Development of example problem manuals for Div 1 and Div 3. The problems solution manual for Section VIII, Division 1 has been published and is available for purchase from ASME( the document # is PTB-4 2012). A problem exists with this manual, the Div. 1 code has changed considerably in some areas during the creation and review of this manual. We are in need of a new revision prior to printing. o Task 4: Identification of Common Rules in Div 2 that be referenced from Div 1 and Div 3 SUMMARY:

I have attempted to condense the many activities of the ASME code committee into a highlight summary for review and information. My objective is to make it as easy as possible for PVMA members to review these items and provide

11

feedback. In this regard anyone can get comments, questions or suggestions to me by letter, phone, FAX or e-mail as noted in the letterhead of this report. Respectfully submitted,

Code Case XXXX Hydrostatic and Pneumatic Testing of Mass Produced Pressure Vessels with an Intermediate Isolation Valve between the Indicating Gage and Pressure Vessel Section VIII, Division 1

Inquiry: When is it permissible during hydrostatic or pneumatic testing to place an intermediate isolation valve between an indicating gage required in UG‐102(a) and a pressure vessel constructed to the requirements of UG‐90(c)(2) and Appendix 35 of Section VIII, Division 1?

Reply: It is the opinion of the Committee that it is permissible during h y d ro st at i c or pneumatic testing of mass produced vessels constructed in accordance with UG‐90(c)(2) and Appendix 35 of Section VIII, Division 1 to place an intermediate isolation valve between the pressure vessel and the indicating gage required by UG‐102(a) when the following conditions are met:

1. The pressure vessel is tested in a test enclosure and the test enclosure may not provide

adequate access to perform inspection in accordance with 35‐6 (f). 2. The intermediate isolation valve is required to maintain pressure in the vessel at a value

of test pressure divided by 1.3 while the vessel is moved from the test enclosure to a location where inspection for leakage is performed.

3. There shall be administrative procedures or valve operation controls to ensure that the intermediate isolation valve is maintained to its full, open position assuring that the pressure vessel is tested to the prescribed test pressure.

4. The manufacturer’s pressure test operating procedures shall describe the following: a) Requirements, operator actions and check points for performing the pressure test and

leakage inspection. b) The intermediate isolation valve setup and operating positions. If electric or

pneumatic controlled valves are used in the test, cell an explanation of the indicating lights, valve positions and valve fail open / closed positions shall be provided.

5. The indicating gage required by UG‐102(a) shall not be isolated from the source of pressure by the intermediate isolation valve.

6. The number of this Code Case shall be noted on the Manufacturer’s Data Report for the vessel.

35-7 Hydrostatic Testing Single chamber pressure vessels, constructed by a Manufacturer under the provisions of Para. UG-90(c)(2), may be pressure tested separately from their its removable covers in a test fixture, and the corresponding bolted blind flange closures pressure tested only on a quality control basis provided all of the following requirements are met:

(a) Only one end of the pressure vessel may consist of a bolted flat blind flange closure. The bolted flat blind flange closure and attachment flange shall comply with the following requirements:

(1) All requirements of ASME B16.5 for bolted flanges. (2) As an alternative to (1) a fabricated flat blind flange may be used provided

it is dimensionally identical to an ASME B16.5 flange or designed in accordance with Appendix 2 and UG-34. A flange dimensionally identical to ASME B16.5 shall use the pressure-temperature rating for the flange construction material and class. A cover and flange designed in accordance with Appendix 2 and UG-34 shall be designed to 1.14 times the vessel MAWP at the design temperature. The vessel shell shall not exceed 30 in. outside diameter. In addition, the ASME B16.5 surface finish and machining requirements shall be met.

(3) The MAWP of the vessel shall not exceed 500 psi (3.45Mpa) and the maximum design temperature shall not exceed 650˚F (343°C).

(4) No welding is permitted on the flat blind flanges. (b) The pressure vessel with open end shall be tested in a fixture that will permit

achieving the test pressure required by UG-99. The vessel shall be mounted to the test fixture in such a manner that the structural integrity and leak tightness of the body flange is established.

(c) One out of every 200 vessels, selected at random, from each day’s production shall be pressure tested per the rules of UG-99 with its removable cover, service gasket and service bolting installed. If this quality control vessel fails the test, then all vessels produced in that day’s production shall be so tested. All vessels in the subject production lot shall consist of identical vessels and design conditions.

(d) The vessel shall not be constructed and stamped for “lethal” service. (e) The The test fixture shall be designed such that the stress developed in the vessel

during the hydrostatic test using the a test fixture shall be the same as the stress developed in the vessel when tested with its removable cover.

GENERAL

The fabrication of pressure vessels and vessel parts shallconform to the general fabrication requirements in the fol-lowing paragraphs and to the specific requirements forFabrication given in the applicable Parts of SubsectionsBand C.

UG-76 CUTTING PLATES A.7IoIl) OTHERSTOCK

(a) Plates, edges of heads, and other parts may be cutto shape and size by mechanical means such as machining,shearing, grinding, or by oxygen or arc cutting. After oxy-gen or arc cutting, all slag and detrimental discoloration.of material which has been molten shall be removed bymechanical means prior to further fabrication or use.

(b) Ends of nozzles or manhole necks which are toremain unwelded in the completed vessel may be cut byshearing provided sufficient additional material is removedby any other method that produces a smooth finish.

(e) Exposed inside edges shall be chamfered or rounded.

UG-77 l\IIATERIAL IDENTIFICATION (SEEUG-85)

(a) Material for pressure parts preferably should be laidout so that when the vessel is completed, one complete setof the original identification markings required by UG-94will be.plainly visible. The pressure vessel Manufacturershall maintain traceability of the material to the originalidentification markings by one or more of the followingmethods: accurate transfer of the original identificationmarkings to a location where the markings will be visibleon the completed vessel; identification by a coded markingtraceable to the original required marking; or recording therequired markings using methods such as material tabula-tions or as built sketches which assure identification ofeach piece of material during fabrication and subsequentidentification in the completed vessel. Such transfers ofmarkings shall be made prior to cutting except that theManufacturer may transfer markings immediately after cut-ting provided the control of these transfers is described inhis written Quality Control System (see 10-6). Except asindicated in (b) below, material may be marked by any

method acceptable to the Inspector. The Inspector neednot witness the transfer of the marks but shall satisfy him-self that it has been correctly done (see UHT-86).

(b) Where the service conditions prohibit die-stampingfor material identification. and when so specified by theuser, the materials manufacturer shall mark the requireddata on the plates in a manner which will allow positiveidentification upon delivery. The markings must berecorded so that each plate will be positively identified inits position in the completed vessel to the satisfaction ofthe Inspector. Transfer of markings for material that is tobe divided shall be done as in (a) above.

(c) Wilen material is formed into shapes by anyone otherthan the Manufacturer of the completed pressure vessel,and the original markings as required by the applicablematerial specification are unavoidably cut out, or the mate-rial is divided into two ormore parts, the manufacturer ofthe shape shall either:

(1) transfer the original identification markings toanother location on the shape; or

(2) provide for identification by the use of a codedmarking traceable to the original required marking, usinga marking method agreed upon and described in the qualitycontrol system of the Manufacturer of the completed pres-sure vessel.

Identification in accordance with UG-93, in conjunctionwith the above modified marking requirements, shall beconsidered sufficient to identify these shapes. Mannfacmr-er's Partial Data Reports and parts stamping are not arequirement unless there has been fabrication to the shapesthat include welding, except as exempted by UG-l I.

Advances in ASME Pressure Vessel Code Design By

Louis E. Hayden, PE Project Manager-Common Rules Task Group ASME BPV Committee on Pressure Vessels

ASME Pressure Technology Sector is continually engaged in advancing the quality and

technology of ASME Codes and Standards. The ASME Boiler and Pressure Vessel Code has

been keeping pace with these advances for over 90 years. In the 1960’s it was recognized that the

special requirements for design of pressure vessels operating at pressures over 2,000 psi (13.7

MPa) would benefit from new design rules, and ASME issued Section VIII, Division 2,

Alternative Rules for Pressure Vessels. Since that time, the technology and understanding of

failure mechanisms and advances in material science, welding, nondestructive examination, and

computer-aided design have progressed to the stage where a new approach was needed to fully

utilize these advances. This new approach was fulfilled when ASME Section VIII, Division 2,

2007 Edition and subsequent addenda and editionsadditions were issued. The development and

issue of Section VIII, Division 2 demonstrated ASME’s commitment to providing manufacturers

and users of pressure equipment with the most up-to-date technology in an easy to use standards

format that serves the global market.

To fully utilize the up-to-date technology contained in Section VIII, Division 2,

recommendations from the Boiler and Pressure Vessel (BPV) Common Rules Task Group along

with the BPV Committee on Pressure Vessels resulted in approval and publication of Code Case

2695 which allows the use of BPV Section VIII, Division 2, Part 4 Design Rules to be used in

the design of Section VIII, Division 1 pressure vessels. A copy of this Code Case is included at

the end of this article.

Some of the advantages of using the design option of Code Case 2695 are savings in material

costs due to reduction in thickness of heads and nozzles for medium to lower design pressures.

Vessels operating at higher pressures using alloy materials will also see a reduction in the

material costs for shells. These savings are realized when using more sophisticated design

methods in Part 4 of Section VIII Division 2.

To aid designers and manufacturers in the design of vessels using Code Case 2695, ASME is

publishing the Section VIII Division 1 example problem manual (PTB-4-2011) in June, 2012. In

this manual, example problems are solved using both the Division 1 and Division 2 rules. When

the design rule is common, the example problem is solved using the Division 2 rules using the

Division 1 allowable stress value and weld joint efficiency. Using this approach, users will

become more familiar and adept at using Division 2. All ASME Certificate Holders for Section

VIII, Division 1 will be able to use this Code Case with their current ASME Certification Mark.

This design approach is a product of the Section VIII Common Rules Task Group review of

Section VIII, Division 1, 2 and 3 rules. Within the three Section VIII Divisions there are many

rules that are common to all Divisions. This commonality of rules located in different books has

become difficult to manage and does not lend itself to rapid introduction of new technologies. To

this end, the Common Rules Task group has developed a plan for rule consolidation within one

Division of Section VIII. The BPV Committee on Pressure Vessels recognizes that Division 2 is

the most technically advanced and best organized for referencing from the other Divisions and

with the exception of overpressure protection requirements, common rules identified by the Task

Group shall reside in Division 2 and be referenced from Division 1 and Division 3, as applicable.

This transition will be controlled by the Common Rules Task Group and Section VIII Standards

Committee over the next several editions.

Core rules for basic pressure vessel design such as wall thickness for shells and formed heads,

nozzle design, etc. will be maintained in Division 1; although different from Division 2 these

rules are time proven and should remain in Division 1 because they provide sufficient design

requirements for many basic pressure vessels.

In brief, the Common Rule Task Group and BPV Committee on Pressure Vessels undertook an

effort to review and identify common rules contained in the Section VIII Division 1, Division 2,

and Division 3 Codes with a goal of developing and implementing a plan to consolidate these

common rules in the best interest of all stake holders, i.e. users of the Code, volunteers, and

ASME. To this end, Code Case 2695 is the start of the transition and consolidation of common

rules.
