Item SG Subject Page(s)

13-29 Items of Interest

Record #09-885: New BPV XII requirement for maintenance of PRVs by uncertified personnel

August 9, 2011: Currently in Section XII industry, they are taking valves off of tanks, cleaning them, replacing parts, not modifying the spring that controls the pressure, but replacing different components for continuous maintenance. There are no rules for this and no rules for who should do this. They want some rules to be written, but they do not want to impose anything new and to keep it very open ended. This was put to a vote a while ago and SVR voted against it. BPV XII wants to go forward with something and the handout is very preliminary. They are looking for feedback from us, NBIC, or whoever is the most appropriate party to give them guidance on the rules, the latest proposal can be found on page 363 of the August 9, 2011 Meeting Minutes. This is going to remain as an item of interest at this committee.

November 8, 2011: Mr. Pittel reported that this was discussed in Section XII. Monte plans to have something for review by mid-next year.

February 7, 2012: Mr. Pittel reported that this is still being worked on. Mr. Ball said that the need in the train industry is that they have tanks which they sometimes want to take the valve off and clean it and put it back together. The proposal from BPV XII was that there could be a valve that could be designated that anyone could repair.

May 15, 2012: Mr. Pittel reported that he talked with Mr. Ball on this. A joint task group will likely need to be created between BPV XII and SVR. Mr. Ball reported that first they were going to propose a type of design with limited adjustment and then mandate that the manufacturer provide information so that these adjustments could be made.

August 14, 2012: Mr. Pittel noted that they are accepting the fact that there are issues with not having certificated individuals doing this maintenance; they are working with the NBIC to develop a resolution. Mr. Ball noted that when this was balloted to BPV XII they got a number

6


of negatives and comments and were going to send it back to whoever was originally working on it.

November 6, 2012: Mr. Pittel reported that there has been no progress on this.

February 12, 2013: Mr. Pittel reported that this is being worked on and discussions are being held with the NBIC; they are trying to definite the problem and get consensus on how to approach this.

August 13, 2013: Project Plan for new UD-3 Certification The publication of Record #01-061 one for the UD-3 certification has been put on administrative

hold until the project plan for the new conformity assessment program has been approved. For a copy of the memo issued by Gerry Eisenberg, Director of Pressure Technology Codes and Standards see pages 268-271 and for a copy of the latest draft of the project plan, see pages 272-273.

BPV IV Interpretation regarding Size of boiler connection and connecting piping between boiler and Safety or Safety Relief Valve (Record #13-871).

For a copy of the record information, see page 274. On page 275 please find a picture of the aluminum Isothermic heat exchanger with undersized safety relief valve connection. The connections on the heat exchanger accept tubing with an inside diameter of approximately 0.669 (one of which is shown in the attached photo). Also on pages 276-279 is a copy of some typical European style wall hung copper fin tube boiler sales literature indicating improper placement of a relief valve. There are several manufacturer's selling similar products based upon this heat exchanger with such mounting. Mr. Bedeaux from the ASME BPV IV Committee will discuss.

13-14 Errata

None 13-15 Next Meeting See page 280 for the list of the future Boiler Code Meetings.

Item 10-1776: Section I PRV and PARV Capacity Certification

SC-SVR History October 26, 2010 – This item was opened between meetings by request of the Project Manager. November 30, 2010 – Curtis Sharpe will be the PM and the task group will consist of Jeramy Dickson and David Scallan. February 1, 2011 – Mr. Sharpe reported that there are changes to 67.5 that need to be reviewed. There are a few editorial changes that need to be made. A task group was formed and they plan to develop a proposal and ballot to the SG-T before the next meeting. April 28, 2011 – Mr. Sharpe reported that the TG is working on a revised proposal. The scope of this item is broader than the title suggests. This item will be broken into three items, one of which is #11-453. The main changes will still be under #10-1776. Mr. Dickson will flow chart the circular reference for this item. Record #11-453 will get a new proposal and another new item may be established for the economizer portion of this item. Mr. Tuttle noted that this item started because super critical steam capacities were added. Mr. Tuttle also noted that he would like to be a part of the working group for this item. August 9, 2011 - Mr. Sharpe reported that they have a new proposal, which is shown on pages 249-259 of the August 9, 2011 Meeting Minutes, for the committee to review. The PM will be uploading the proposal and will notify the Secretary when they have done so and this will be sent for ballot. Mr. Danzy noted that there is some urgency for this revision because of the way power actuated valves are affected by it. Alan West noted that the next edition of the code will not be until July 2013 so the power actuated portion may need to be issued as a Code Case/or Intent Interpretation. Mr. Danzy and Mr., Tuttle will create the intent interpretation request and separate out of the proposal the remaining changes which will not be included with the Intent Interpretation. – Record #11-1459 was opened for this. November 8, 2011 – Mr. Hart reported that this item is on hold pending the outcome of the intent interpretation that is being processed in SG-D. February 7, 2012 – Mr. Sharpe reported that this item is on hold pending intent interpretation #11-1459. May 15, 2012 – This item is loosely linked to #11-1459. As soon as #11-1459 is complete, this proposal will be modified accordingly and will be sent for ballot. August 14, 2012 – Mr. Cox reported that there were minor changes made to the proposal by the subgroup. The proposal was uploaded to the record on CS Connect and the explanation

19

Item 10-1776: Section I PRV and PARV Capacity Certification [Continued]

and summary of changes were updated as well. This item is now ready for ballot to Subcommittee Safety Valve Requirements. November 6, 2012 – This item will be sent for a recirculation ballot; the PM will post the necessary responses and then ballot will be issued before the next meeting. February 12, 2013 – Mr. Sharpe reported that this item was balloted and was disapproved with one negative. Mr. Sharpe will be modifying the proposal accordingly and the proposal will be sent for a recirculation ballot. August 13, 2013 -

Frank Richter

Subject

Section VIII, Division 1; Correction of reference paragraphs for Ovepressure Protection in the

Scope and Subsections.

Proposal

Revise paragraph U-1(f) to indicate the correct paragraph references for overpressure

protection (UG-125 through UG-140 and Appendix 11).

Revise all subsections to have similar sentence structure and reference paragraph U-1(f). By

doing so, all subsections will be consistent and if the Overpressure Protection section is

modified, only one paragraph reference, U-1(f), would need to be revised.

Section U-1(f) referenced overpressure sections UG-125 through UG-137. Paragraph was

revised to include all overpressure protection sections (UG-125 through UG-140).

In addition, the following subsections were revised to make reference to U-1(f) rather than the

individual subsections for overpressure protection. Subsections: UW-65, UB-60, UCS-125,

UNF-125, UHA-65, UCI-125, UCL-60, UCD-125, UHT-125, ULW-125.

UF-125, ULT-125 and UIG-125 were revised to change references as noted above as well as

the sentence structure was changed to make them the same as UW-65, UB-60, UCS-125,

UNF-125, UHA-65, UCI-125, UCL-60, UCD-125, UHT-125 and ULW-125.

The terminology "Pressure Relief Device" was replaced with "Overpressure Protection"

throughout the affected paragraphs commensurate with the incorporation of overpressure

protection by system design in UG-140.

Item 11-2106; BPV VIII; Correct Overpressure Protection Subsections

SC-SVR History

November 8, 2011 – This item was initiated at the meeting and was assigned to Subgroup Testing. Alton Cox will be the temporary PM until someone else is assigned. This item will affect sections UW-65, UF-125, UB-60, UCS-125, UNF-125, UHA-65, UCI-125, UCL-60, UCB-125, UHT-125, ULT-125. February 7, 2012 – Mr. Cox reported that the PM needs to be changed to Mr. Dickson. Mr. Dickson then reported that this item was submitted to SC-SVR for review. There are 16 sections within BPV VIII and at the end of each there is a paragraph that refers you to the relevant UG Section. There have been additions to the UG paragraphs and these references have not been accordingly revised. The PM will be reviewing each of these and will determine what the appropriate references are. May 15, 2012 – Mr. Cox reported that there is a proposal drafted for this item which is ready for ballot to the BPV SC-SVR SG-Testing. Mr. Dickson will contact the Secretary to initiate the ballot when the item is ready. August 14, 2012 – Mr. Cox reported that this item is ready for ballot to SC-SVR, the secretary will initiate the ballot. November 6, 2012 – The PM noted that this item received a comment on the latest ballot indicating that there is a typo in the last two items. He agrees with the commenter and will be revising the proposal accordingly and will send it for a recirculation ballot. February 12, 2013 – Mr. Hart reported that this item was disapproved by SC-SVR. Mr. Nutter provided a handout to the committee which was reviewed at the meeting. Mr. DeMichael suggested that UG-125 be added to the record as background material. The Secretary reminded Mr. Nutter that responses need to be posted on C&S Connect before this item can move forward. Once this is done Mr. Nutter will send a note to the secretary and a new first consideration ballot will be issued. August 13, 2013 -

(f) For sample forms and guidance in their preparation,see Appendix W.

OVERPRESSURE PROTECTION

UG-125 GENERAL

(a) Other than unfired steam boilers, all pressure vesselswithin the scope of this Division, irrespective of size orpressure, shall be provided with overpressure protectionin accordance with the requirements of UG-125 throughUG-138 and/or overpressure protection by system designper UG-140. Unfired steam boilers shall be provided withoverpressure protection in accordance with the require-ments of UG-125 through UG-138. In addition, the follow-ing shall apply:

(1) It is the user’s or his/her designated agent’sresponsibility to identify all potential overpressure scenar-ios and the method of overpressure protection used tomitigate each scenario.

(2) It is the responsibility of the user to ensure thatthe required overpressure protection system is properlyinstalled prior to initial operation.

(3) If a pressure relief device(s) is to be installed, itis the responsibility of the user or his/her designated agentto size and select the pressure relief device(s) based onits intended service. Intended service considerations shallinclude, but not necessarily be limited to, the following:

(a) normal operating and upset conditions(b) fluids(c) fluid phases

(4) The overpressure protection system need not besupplied by the vessel Manufacturer.

(5) Unless otherwise defined in this Division, thedefinitions relating to pressure relief devices in Section 2of ASME PTC 25 shall apply.

(b) An unfired steam boiler shall be equipped with pres-sure relief devices required by Section I insofar as theyare applicable to the service of the particular installation.

(c) Other than unfired steam boilers, when a pressurerelief device is provided, it shall prevent the pressure fromrising more than 10% or 3 psi (20 kPa), whichever isgreater, above the maximum allowable working pressureexcept as permitted in (1) and (2) below and UG-127(d)(3).(See UG-134 for pressure settings.)

(1) When multiple pressure relief devices are pro-vided and set in accordance with UG-134(a), they shall

90

prevent the pressure from rising more than 16% or 4 psi(30 kPa), whichever is greater, above the maximum allow-able working pressure.

(2) When a pressure vessel can be exposed to fire orother unexpected sources of external heat, the pressurerelief device(s) shall be capable of preventing the pressurefrom rising more than 21% above the maximum allowableworking pressure. Supplemental pressure relief devicesshall be installed to protect against this source of excessivepressure if the pressure relief devices used to satisfy thecapacity requirements of UG-125(c) and UG-125(c)(1)have insufficient capacity to provide the required protec-tion. See Nonmandatory Appendix M, para. M-13 for caseswhere the metal temperature due to fire or other sourcesof external heat can cause vessel failure prior to reachingthe MAWP.

(3) Pressure relief devices, intended primarily forprotection against exposure of a pressure vessel to fire orother unexpected sources of external heat installed on ves-sels having no permanent supply connection and used forstorage at ambient temperatures of nonrefrigerated lique-fied compressed gases,42 are excluded from the require-ments of (c)(1) and (c)(2) above, provided:

(a) the pressure relief devices are capable of pre-venting the pressure from rising more than 20% above themaximum allowable working pressure of the vessels;

(b) the set pressure marked on these devices shallnot exceed the maximum allowable working pressure ofthe vessels;

(c) the vessels have sufficient ullage to avoid aliquid full condition;

(d) the maximum allowable working pressure ofthe vessels on which these pressure relief devices areinstalled is greater than the vapor pressure of the storedliquefied compressed gas at the maximum anticipated tem-perature43 that the gas will reach under atmospheric condi-tions; and

(e) pressure relief valves used to satisfy these pro-visions also comply with the requirements ofUG-129(a)(5), UG-131(c)(2), and UG-134(d)(2).

(d) Pressure relief devices shall be constructed, located,and installed so that they are readily accessible for testing,inspection, replacement, and repair and so that they cannotbe readily rendered inoperative (see Appendix M).

(e) Pressure relief valves or nonreclosing pressure reliefdevices44 may be used to protect against overpressure.

42 For the purpose of these rules, gases are considered to be substanceshaving a vapor pressure greater than 40 psia (300 kPa absolute) at100°F (40°C).

43 Normally this temperature should not be less than 115°F (45°C).44 A pressure relief valve is a pressure relief device which is designed

to reclose and prevent the further flow of fluid after normal conditionshave been restored. A nonreclosing pressure relief device is a pressurerelief device designed to remain open after operation.

SUBJECT: Background File for Item 11-2106

DATE: February 28, 2012 Team: This item was referred to our committee for review on the discrepancy that each of the sub-sections of ASME Section VIII-1 referenced the incorrect paragraph ranges that are applicable to pressure relief devices. In efforts to keep future revisions of the Standard consistent, I am proposing that each sub-section be revised to the same sentence structure and refer back to Section U where only one paragraph has to be revised. Section VIII-1 has the following sections:

(f) a vessel for containing water1 under pressure,including those containing air the compression of whichserves only as a cushion, when none of the followinglimitations are exceeded:

(1) a design pressure of 300 psi (2 MPa);(2) a design temperature of 210°F (99°C);

(g) a hot water supply storage tank heated by steamor any other indirect means when none of the followinglimitations is exceeded:

(1) a heat input of 200,000 Btu/hr (58.6 kW);(2) a water temperature of 210°F (99°C);(3) a nominal water containing capacity of

120 gal (450 L);(h) vessels not exceeding the design pressure (see

3-2), at the top of the vessel, limitations below, with nolimitation on size [see UG-28(f), 9-1(c)]:

(1) vessels having an internal or external pres-sure not exceeding 15 psi (100 kPa);

(2) combination units having an internal orexternal pressure in each chamber not exceeding 15 psi(100 kPa) and differential pressure on the common ele-ments not exceeding 15 psi (100 kPa) [see UG-19(a)];

(i) vessels having an inside diameter, width, height,or cross section diagonal not exceeding 6 in. (152 mm),with no limitation on length of vessel or pressure;

(j) pressure vessels for human occupancy.2

U-1(d) The rules of this Division have been formulatedon the basis of design principles and construction practicesapplicable to vessels designed for pressures not exceeding3000 psi (20MPa).

UCL-40 WELDING PROCEDURES

Welding procedures for corrosion resistant weld overlay,composite (clad) metals, and attachment of applied liningsshall be prepared and qualified in accordance with therequirements of Section IX.

UCL-42 ALLOY WELDS IN BASE METAL

Groove joints in base material and parts may be madewith corrosion resistant alloy-steel filler metal, or groovejoints may be made between corrosion resistant alloy steeland carbon or low alloy steel, provided the welding proce-dure and the welders have been qualified in accordancewith the requirements of Section IX for the combinationof materials used. Some applications of this rule are basemetal welded with alloy-steel electrodes, and alloy nozzleswelded to steel shells.

UCL-46 FILLET WELDS

Fillet welds of corrosion resistant metal deposited incontact with two materials of dissimilar composition maybe used for shell joints under the limitations of UW-12,for connection attachments under the limitations of UW-15and UW-16, and for any other uses permitted by this Divi-sion. The qualification of the welding procedures and weld-ers to be used on fillet welds for a given combination ofmaterials and alloy weld metal shall be made in accordancewith the rules prescribed in Section IX.


UCL-50 GENERAL

The rules in the following paragraphs apply specificallyto the inspection and testing of pressure vessels and vesselparts constructed of base material with corrosion resistantintegral or weld metal overlay cladding and those havingapplied corrosion resistant linings, and shall be used inconjunction with the general requirements for Inspectionand Tests in Subsection A, and with the specific require-ments for Inspection and Tests in Subsection B that pertainto the method of fabrication used.

UCL-51 TIGHTNESS OF APPLIED LINING

A test for tightness of the applied lining that will beappropriate for the intended service is recommended, butthe details of the test shall be a matter for agreement

228

between the user and the manufacturer. The test should besuch as to assure freedom from damage to the load carryingbase material. When rapid corrosion of the base materialis to be expected from contact with the contents of thevessel, particular care should be taken in devising andexecuting the tightness test.

Following the hydrostatic pressure test, the interior ofthe vessel shall be inspected to determine if there is anyseepage of the test fluid through the lining. Seepage ofthe test fluid behind the applied lining may cause seriousdamage to the liner when the vessel is put in service. Whenseepage occurs, F-4 of Appendix F shall be consideredand the lining shall be repaired by welding. Repetition ofthe radiography, and heat treatment, or the hydrostatic testof the vessel after lining repairs is not required exceptwhen there is reason to suspect that the repair welds mayhave defects that penetrate into the base material, in whichcase the Inspector shall decide which one or more shallbe repeated.

UCL-52 HYDROSTATIC TEST

The requirements for standard hydrostatic test in UG-99shall apply to pressure vessels fabricated in accordancewith the rules of Part UCL.

MARKING AND REPORTS

UCL-55 GENERAL

The provisions for marking and reports in UG-115through UG-120 shall apply to vessels that are constructedof base material with corrosion resistant integral or weldmetal overlay cladding and those having applied corrosionresistant linings, with the following supplements to theData Reports.

suggest the following: "The provisions for overpressure

protection in U-1(f) shall apply to vessels constructed to

this Part with the additional requirement that the safety

relief device be suitable for low temperature service and

installed to remain at ambient temperature except when

relieving."

Thank you for your comment and proposed improvement.

We will incorporate your suggestion and offer the item for

recirculation ballot.

Code Case

Project Manager

Dean Miller

Subject

Code Case to delay implementation of record #01-061

Proposal

Adopt a new Code Case to postpone the requirement for rupture disk devices to carry the

ASME Certification Mark and applicable Designator as described in KR-200(a) until January

1, 2015

The 2013 Edition of ASME Section VIII, Division 3 will incorporate item 01-061 into the

Code. This change requires all bursting disk devices used on Division 3 vessels to be marked

with the ASME Certification Mark and applicable Designator. By default this requirement will

become mandatory on January 1, 2014. This provides only six months for manufacturers to

identify designs that are used on Division 3 vessels, submit application to the ASME Designated

Organization and get production testing scheduled and performed. With some devices being

manufactured by differing rupture disk and holder manufacturers this process will be even more

time consuming. Since this item also includes the creation of new ASME Scopes of

Authorization and there are many manufacturers of these devices it is very likely that many of the

devices used today will not have completed the certification process by January 1, 2014. The

objective of the Code Case is to delay the mandatory implementation of these requirements to

allow manufacturers sufficient time to pursue the necessary device certifications and prevent

users from being put in the position of having to knowingly violate Code rules by applying

non-certified devices.

Item 13-495: Code Case to Delay Implementation of #01-061

SC-SVR History February 12, 2013 – Mr. Miller reported that this item is a byproduct of #01-061. It entails establishment of new scopes of authorization as well as a new process for manufacturers to have time to prepare and implement some of the devices. As written now, the code would require that all devices to be stamped on Jan 1, 2014 and this is to delay that mandate by one year. Mr. West requested that the proposal for this item be developed and balloted prior to the May BCW. August 13, 2013 -

Case XXXX Implementation of ASME Certification Mark and Applicable Designator. Section VIII, Division 3 Inquiry: In the 2013 Edition of the ASME Section VIII, Division 3 paragraph KR-200(a) adds a new requirement for rupture disk devices to carry the ASME Certification Mark with the applicable UD or UD3 Designator. May rupture disk devices for use on Division 3 vessels without the ASME Certification Mark continue to be used beyond the six-month period after which revisions to the Code published in the 2013 Edition become mandatory? Reply: It is the opinion of the Committee that the implementation of the requirement for rupture disk devices to carry the ASME Certification Mark and applicable Designator as described in KR-200(a) may be postponed until January 1, 2015.

Section VIII, Division 1; Revision to paragraph UG-136(d)(2), UG-137(d)(2), and

UG-38(d)(2) Hydrostatic Pressure Test

Proposal

To revise paragraphs UG-136(d)(2), UG-136(d)(3), UG-137(d)(2), and UG-38(d)(2).

The paragraphs UG-136(d)(2), UG-136(d)(3), UG-137(d)(2),and UG-138(d)(2) Hydrostatic

Pressure Test of Section VIII, Division 1 needs to be revised to clarify: a) clarify that pressure

testing is required and not restricted to hydrostatic testing, b) state what components require

pressure testing; c) the conditions for exempting components from pressure testing; d) the

option of either testing hydrostatically or pneumatically and, e) remove visible as a requirement

for test acceptance.

Explanation

Summary of ChangesRevised paragraphs UG-136(d)(2), UG-137(d)(2), and UG-138(d)(2) changing the subject

from "hydrostatic testing" to "pressure testing", revised content to better define the parts

exempted from testing and deleted the word "visible" with regards to acceptance criteria.

Delete the word "visible" from UG-136(d)(3)

Item 08-1594: BPV VIII-1; Revision to para UG-136(D)(2), UG-137(D)(2), and UG-138(D)(2) Hydrostatic Pressure Test

SC-SVR History November 3, 2009 – This item is currently being worked on within Section VIII-1.

February 2, 2010 – Mr. Doelling reported that they are trying to get the requirements in Section I to be the same as those in Section VIII. This item is currently at BPV VIII SG-GR.

August 3, 2010 – This item is still at BPV VIII SG-GR. November 30, 2010 – This item is still at the BPV VIII SG-GR. Mr. Patel is still shown as the Project Manager. He has updated the proposal, approved by this committee, from the 2007 Edition of the Code to the 2010 Edition. As a courtesy Mr. Patel will forward this to BPV VIII SG-GR however, once an item has left SC-SVR we do not have the responsibilities to update the proposal to current Code. February 1, 2011 – Mr. Patel reported that this item is with BPV VIII SG-GR and there is no progress since the last meeting. April 28, 2011 - This item is at BPV VIII SG-GR and there has been no action to date. August 9, 2011 - Mr. Patel reported that this item is currently within BPV VIII SG-GR. It was balloted in July and was approved. There were some negatives because the proposal said 2007 over the 2011 edition. Mr. Patel created a new proposal with the same revisions using the 2011 Edition. There was not much difference between the 2007 and 2011 wording except that para 136(d)(2)(d) was removed in the 2011 edition and there were objections to removing the word “visible” in subparagraph (e). Visible was already removed in Section I and we are trying to match the wording in Section VIII. Mr. Patel will give copies of the new proposal to Mr. DeMichael or Mr. Danzy to provide to the BPV VIII PM. It was also suggested that the word “may” be removed. November 8, 2011 – Mr. Danzy reported that this item is currently in Section VIII. This item was discussed at the August meeting of Section VIII SG-GR and they felt that the wording was confusing. This item will be discussed at the meeting tomorrow, both Mr. West and Mr. Danzy plan to attend. February 7, 2012 – Mr. Danzy reported that this item was approved by the SC-SVR and was referred to BPV VIII. The Standards Committee balloted and revised the proposal, approved it and sent it back to SC-SVR for review. This item will be dropped back down to Items in Progress. There will be a new ballot to SC-SVR regarding this item before the next meeting. May 15, 2012 – This item has been returned to SC-SVR to rework and will be moved back to items in progress on the agenda. The proposal in CS Connect is correct and is ready for ballot to BPC SC-SVR.

Item 08-1594: BPV VIII-1; Revision to para UG-136(D)(2), UG-137(D)(2), and UG-138(D)(2) Hydrostatic Pressure Test [Continued]

August 14, 2012 – Mr. Danzy reported that this item was balloted and received some comments which have been resolved. He will post responses to all of the comments on CS Connect and will notify the secretary when this has been completed so that the item can move forward. November 6, 2012 – This item was approved by SC-SVR with comments. The PM will post the final responses and will notify the secretary and the item will be transferred to the Standards Committee. February 12, 2013 – This item has been approved by SC-SVR and has been forwarded to BPV VIII SG-GR for consideration. This item can be moved to items referred. August 13, 2013 -

Item 10-1412: Section XII; Use of the “TV” and “TD” Designators in accordance with CSP-53

SC-SVR History August 3, 2010 – This item was opened regarding the use of the “TV” and “TD” Code Symbol Stamps, in accordance with CSP-53, in response to item #12 of list of requests to the BPV SC-SVR from BPV XII via record #04-20. November 30, 2010 – No action to report on this item. February 1, 2011 - Mr. DeMichael reported that items 10-1409, 10-1410, 10-1411and 10-1412 will be included in note to BPV XII for clarification with Modal Appendices. April 28, 2011 - This and several other items have to do with comments from Mr. Tanner that came from #04-20. The PM’s of these items sent notice to Mr. DeMichael. Nothing has been received yet. However, Mr. DeMichael is arranging to discuss these items with members of Section XII at the Las Vegas meeting. August 9, 2011 - Mr. DeMichael noted that there is no reason to hold this item up due to the Modal Appendixes and the PM will move forward with a proposal for this. November 8, 2011 – Mr. Richardson reported that this item was generated in response to a comment by Mr. Tanner. They were delayed for a while pending clarification regarding the modal appendices. However, they will now be moving forward and providing general requirements. A proposal was provided to the subgroup for review and the PM plans to have a proposal for action by SG-GR by the next meeting. February 7, 2012 – Mr. Ball reported that John Richardson and Dave Parrish have been working on this item. A proposal was distributed at the SG-GR meeting. Once the PM incorporates the comments from the SG meeting it will be uploaded to CS Connect and a request will be sent to the secretary to initiate a ballot to SG0GR. Mr. Richardson noted that the forms will need to be added to Section XII. May 15, 2012 – Mr. Richardson reported that this item was initiated in response to Mr. Tanners comments. The proposal has been completed and updated on CS Connect. This was discussed at SG-GR and they feel that it is ready for ballot. The secretary will initiate a ballot to SG-GR. August 14, 2012 – Mr. Richardson reported that this item came from Mr. Tanners comments on Section XII. A proposal was put forward and balloted in SG-GR and was approved with a comment. There is one word in the current proposal which needs to be corrected, the PM will do so and will notify the secretary when the record has been updated. This item will then proceed to the SC-SVR for ballot. November 6, 2012 – Mr. Richardson reported that this item is currently out for ballot and has not received any comments so far.

tion Organization shall have and maintain a quality controlsystem that will establish that all Code requirements,including material, design, fabrication, examination (bythe Manufacturer, Repair, and Relief Valve RecertificationOrganization), and for vessels and vessel parts, inspection(by the Inspector), will be met. Provided that Coderequirements are suitably identified, the system mayinclude provisions for satisfying any requirements bythe Manufacturer, or User, which exceed minimum Coderequirements and may include provisions for qualitycontrol of non-Code work. In such systems, the Manufac-turer of vessels or vessel parts may make changes in partsof the system that do not affect the Code requirementswithout securing acceptance by the Inspector. Beforeimplementation, revisions to quality control systems ofManufacturers and Assemblers of pressure-reliefvalves shall have been found acceptable to the ASME-designated organization if such revisions affect Coderequirements.

The system that the Manufacturer uses to meet therequirements of this Section must be one suitable for hisown circumstances. The necessary scope and detail of thesystem shall depend on the complexity of the work/"performed and on the size and complexity of theManufacturer's organization.f ' A written description ofthe system the Manufacturer will use to produce aCode item shall be available for review. Depending uponthe circumstances, the description may be brief orvoluminous.

The written description may contain information of aproprietary nature relating to the Manufacturers orprocesses. Therefore, the Code does not require anydistribution of this information except for the Inspector,ASME Designee, or an ASME-designated organization ascovered by I15(c) and I16(c). It is intended that informa-tion learned about the system in connection with theevaluation will be treated as confidential and that allloaned descriptions will be returned to the Manufacturerupon completion of the evaluation.

12 OUTLINE OF FEATURES TO BE INCLUDEDIN THE WRITTEN DESCRIPTION OF THEQUALITY CONTROL SYSTEM

The following is a guide to some of the features thatshould be covered in the written description of the QualityControl System and that is equally applicable to both shopand field work.

Code Case

Project Manager

Denis DeMichael

Subject

Section VIII, Division 1; Code Case regarding Multiple Marking of Certified Capacities for

Pressure Relief Valves

Proposal

Adopt the Code Case as shown in the Proposal file.

There are many capacity certified direct spring loaded and pilot operated pressure relief valves

that are certified for steam, gas (air) and/or liquid (water) that will perform to all ASME Section

VIII Div 1 requirements when set and tested for one capacity certification and without

adjustments or changes to their parts will perform to all ASME Section VIII, Div 1

requirements for their other capacity certifications. At present even under the performance

capabilities noted, only one of the capacity certifications can be marked on the valve or its

nameplate and the end user can only apply the pressure relief valve to applications related to the

marked capacity certification.

It is noted that rupture disks may be marked for all applicable capacity certifications, see

UG-129(e)(9).

Item 10-1784: Section VIII Code Case regarding Multiple Marking of Certified Capacities for Pressure Relief Valves

SC-SVR History October 27, 2010 – This item was opened between meetings. November 30, 2010 – This item was assigned to Dave Tuttle. Mr. Tuttle reported that he expects to have a proposal for review at the next meeting. February 1, 2011 – Mr. DeMichael provided a progress report. The Subgroup went through each item of the Code Case and provided comments to the Project Manager for consideration. Any comments should be sent to Dave Tuttle for consideration.

April 28, 2011 – Mr. Tuttle reported that this Code Case is to allow marking of multiple capacities on the relief valves. His basis for his proposal comes from what was done on rupture discs for multiple capacities.

Mr. Tuttle’s proposal was reviewed by the subgroup and was revised by them. The proposal was shown to the members as a progress report and was discussed. This item will be revised by the subgroup at their next meeting and will then be brought to SC-SVR for ballot after their review.

Jeramy Dickson noted that something in the code case needs to be added regarding what will be written on the UV-1 form.

Mr. Tuttle requested that everyone with comments or concerns with this proposal send their suggestion to him for consideration of inclusion in the next revision of this case. August 9, 2011 - Mr. Tuttle reported that at the last meeting, the item was held because Roger hadn’t seen the proposal yet. He has reviewed it and the subgroup reaffirmed the proposal. Alan West noted two revisions to the code case request that he would like made before this item proceeds to ballot. At the last meeting, Mr. Dickson also wanted to know where the media was to be included on the stamp. Mr. Tuttle will revise the proposal and this item will then be sent for ballot. November 8, 2011 – Mr. Tuttle reported that this ballot received several disapprovals. The negatives were discussed and Mr. Tuttle noted that he will make revisions to the proposal based on the negatives he received. He will be updating the record and will get it ready for another round of balloting. February 7, 2012 – Mr. Ball reported that ballot #12-80 closed with three negatives. Mr. DeMichael plans to withdraw his negative and the other comments will require editorial revisions; this item will be recirculated when the proposal is revised. May 15, 2012 – Mr. DeMichael reported that this item has been through a first consideration ballot to SC-SVR. It received negatives which have been addressed.

Proposal

Approve the Code changes shown in the proposal.

The no longer utilized log-log plotting process in UG-131(d)(2)(b) is replaced with current

industry method of flow factor capacity certification for liquid pressure relief valves.

The format of slope certification in UG-131(d)(2)(a) is revised to mirror the flow factor

incorporation. Redundant equations for rated capacity based on set and overpressure are also

removed from UG-131(d)(2)(a).

A code rule located in a note in UG-131(e)(2) is incorporated into body text of UG-131(e)(2).

Item 10-1877: Section VIII-1 UG-136(d)(2)(b) and UG-136(e)(2) Liquid Capacity Certification

SC-SVR History November 8, 2010 – This item was opened between meetings. November 30, 2010 – PM was changed to Mr. Wang and the task group will consist of Greg Goodson and Sid Cammerisi. February 1, 2011 – Mr. Cox reported that the PM needs to be changed to Brandon Nutter. Mr. Nutter then reported that this item is a change from what’s required in the code to what’s actually practiced in industry. The subgroup received a proposed revision to the code (Feb. 2011 minutes pages 256-258). Brandon noted that there are a few things that need to be worked on before the item moves forward. The task group will consist of J. Dickson, Z. Wang, J. Goodson and S. Cammerisi. There will be a ballot before then next meeting.

April 28, 2011 – Mr. Nutter provided a handout for the committee to review. Mr. Nutter reviewed the rationale of this revision to bring the code in line with current industry practices.

The proposal provided was a revised draft created by the subgroup on Testing. The committee reviewed the proposal. Mr. Nutter noted that h would like to have Joe Ball review the proposal before it goes out for ballot to the entire committee. After Mr. Ball reviews the proposal, Mr. Nutter will send a request to the secretary to initiate the ballot before the next meeting.

August 9, 2011 - There have been some Task Group meetings and they have requested to bring this item back to the Task Group level. The Task Group plans to revise the scope of this item and do some further work on it before it is presented again to the Subcommittee. Mr. Nutter noted that, during discussions with several of the interested parties, it came to light that the coefficient of discharge method for all device certifications might be something they want to look at. Any members who would like to be a part of the TG should notify Mr. Nutter. November 8, 2011 – There have been a lot of comments received on the latest proposal and has been brought back to the task group for further work. February 7, 2012 – Mr. Nutter reported that this item began with an inquiry from Mr. Danzy. The proposal that he supplied incorporated several things including the log-log plotting method for liquid capacity certification. He proposed that we incorporate the industry standard flow factor certification method. He also proposed that we change the liquid capacity certification to a volumetric certification rather than the mass. The TG will be work on a proposal to correct the rules as they are now and then go back to the additional information on volumetric and coefficient of discharge methods on another item. They plan to have a proposal by the next meeting. May 15, 2012 – There was a task group teleconference and they agreed to revise the scope of record #10-1877 to address UG-136(d)(2)(b) only to eliminate the log-log and to instead

84

Item 10-1877: Section VIII-1 UG-136(d)(2)(b) and UG-136(e)(2) Liquid Capacity Certification [Continued]

describe the actual practice. Mr. Nutter will send a request to the Secretary to open new items for the inquiry as well as new items to address the issues that came up during the review of the proposal. August 14, 2012 – Mr. Nutter reported that he has further revised the proposal, a copy of the revised proposal can be found on pages 292-397 of the August 14, 2012 Meeting Minutes. Mr. Nutter reviewed the proposal with the committee and they agreed to open a new item at the subgroup level to review the other portion of Mr. Danzy’s issues. Mr. Danzy added that this item can go forward for the flow factor portion. Mr. Danzy further noted that the statement being removed about failure to meet the requirements is in the wrong location and that it shouldn’t be deleted all together. Mr. Nutter will revise the proposal to avoid the issue of the failure to meet the requirements. November 6, 2012 – On the first ballot for this item (#12-204), there were a few comments made which were corrected in a recirculation ballot. During the recirculation ballot, Mr. Glaspie noted that there was a missing subscript which is a typographical error.

MOTION was made to add subscript M to the S as shown in the proposal as shown on pages 66-71 of the November 6, 2012 Meeting Minutes. Motion was seconded and APPROVED.

The corrected proposal will be uploaded to CS Connect and this item will be referred to the Standards Committee. February 12, 2013 – This item was approved by the subcommittee and some editorial changes were introduced; it is currently listed as standards committee proposal. August 13, 2013 -

Item 11-311: Section XII, TR-100 through TR-140 – General Requirements

SC-SVR History February 8, 2011 – This item was opened between meetings. April 28, 2011 – Mr. Pittel noted that the original proposal for this was reviewed and commented on. This will be revised and submitted at the next meeting for voting. August 9, 2011 - Mr. Pittel reported that this item is for general updates for PRV and RD. This item is not a large update and it is currently being voted on. When the ballot closes the PM will take the comments into consideration including how to handle the Modal Appendixes. November 8, 2011 – Mr. Pittel reported that this item was sent for ballot and was reviewed by members of the SC-SVR SG-GR which came back with comments and disapprovals. The item will be revised in response to those comments as well as some additional changes allowing the modal appendices to override the TR sections. He hopes to have this proposal balloted to SG-GR prior to the next meeting. February 7, 2012 – Mr. Ball reported that this item considers some General Requirements fixes in BPV XII. Mr. Pittel reported that he has the SG review his markup and he made some further changes to it. The new mark-up is posted on CS Connect and there is one additional issue that needs to be revised. Once the proposal is ready for ballot the PM will request that the secretary initiate a ballot to SG-GR and then that will hopefully be followed by a ballot to SC-SVR. May 15, 2012 – Mr. Pittel reported that this item was balloted to and APPROVED by SG-GR. This is now ready to be sent for ballot to SC-SVR. August 14, 2012 – Mr. Pittel reported that he has reviewed all of the comments and negatives associated with the ballot and only formatting changes are necessary to the proposal. Mr. Pittel will modify the proposal and upload it to CS Connect. He will then notify the Secretary and the item will move forward. November 6, 2012 – Mr. Tuttle reported that this item has passed SG-GR and has been sent up to the BPC XII Standards Committee for action.

of 3 Item #: 11-311 Rev.: 05-10-2012 (header added 08-13-2012)

(a) All transport tanks within the scope of this Section, irrespective of size or pressure, shall be provided with overpressure protection in accordance with the requirements of this Part, as set forth in Articles TR-1 through TR-5, except as permitted by the applicable Modal Appendix, and the following shall apply. It is the user’s or his/her designated agent’s responsibility to identify all potential overpressure scenarios and the method of overpressure protection used to mitigate each scenario. It is the responsibility of the user to ensure that the required overpressure protection system is properly installed prior to initial operation. It is the responsibility of the user or his/her designated agent to size and select the pressure relief device(s) based on its intended service. Intended service consideration shall include, but not necessarily be limited to, the following: (a) normal operating and upset conditions, (b) fluids, (c) fluid phases. The overpressure protection system need not be supplied by the vessel Manufacturer. Transport tank or tank is an all-inclusive term comprising pressure vessel, service equipment, and external structural components. (d) As an alternative to the stamping requirements of this Section, pressure relief devices certified for service in unfired pressure vessels per Section VIII Division 1 may be used for Section XII applications if it meets the additional requirements of Section XII, particularly the Modal Appendices.

94


Pressure relief device(s) shall be readily accessible for testing, inspection, replacement, and repair. Pressure relief devices shall be installed to minimize the potential for damage or otherwise being rendered inoperable during expected operating conditions. (b) The opening through all pipe, fittings, and nonreclosing pressure relief devices (if installed) between a transport tank and its pressure relief valve shall have at least the area of the pressure relief valve inlet. The characteristics of this upstream system shall be such that the pressure drop will not reduce the relieving capacity below that required or adversely affect the proper operation of the pressure relief valve. The opening in the transport tank wall shall be designed to provide unobstructed flow between the vessel and its pressure relief valve. (c) When two or more required pressure relief devices are placed on one connection, the inlet internal cross-sectional area of this connection shall be either sized to avoid restricted flow to the pressure relief devices or made at least equal to the combined inlet areas to the pressure relief devices connected to it. The flow characteristics of the upstream system shall satisfy the requirements of (b) above. (d) There shall be no intervening stop valves between the vessel and its pressure relief device or devices, or between the pressure relief device and the point of discharge. (e) The pressure relief devices on all transport tanks shall be so installed that their proper functioning will not be hindered by the nature of the transport tank’s contents.

95


(f) Discharge lines from pressure relief devices shall be designed to facilitate drainage or shall be fitted with drains to prevent liquid from lodging in the discharge side of the pressure relief device, and such lines shall lead to a safe place of discharge. The size of the discharge lines shall be such that any pressure that may exist or develop will not reduce the relieving capacity of the pressure relief devices below that required to properly protect the vessel, or adversely affect the proper operation of the pressure relief devices.
