19、ting for Repairsand Alterations 211iiiCopyright ASME International Provided by IHS under license with ASME Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-FOREWORDASME formed an Ad Hoc Task Group on Post Construction in 1993 in response to an increasedneed for reco
20、gnized and generally accepted engineering standards for the inspection and mainte-nance of pressure equipment after it has been placed in service. At the recommendation of thisTask Group, the Board on Pressure Technology Codes and Standards (BPTCS) formed the PostConstruction Committee (PCC) in 1995
21、. The scope of this committee was to develop and maintainstandards addressing common issues and technologies related to post-construction activities andto work with other consensus committees in the development of separate, product-specific codesand standards addressing issues encountered after init
22、ial construction for equipment and pipingcovered by Pressure Technology Codes and Standards. The BPTCS covers non-nuclear boilers,pressure vessels (including heat exchangers), piping and piping components, pipelines, andstorage tanks.The PCC selects standards to be developed based on identified need
23、s and the availability ofvolunteers. The PCC formed the Subcommittee on Inspection Planning and the Subcommitteeon Flaw Evaluations in 1995. In 1998, a Task Group under the PCC began preparing Guidelinesfor Pressure Boundary Bolted Flange Joint Assembly. In 1999, the PCC formed the Subcommitteeon Re
24、pair and Testing. In 2002, the Subcommittee on Flaw Evaluation was dissolved and replacedby the Joint ASME/API Committee on Fitness for Service. Other topics are under considerationand may be developed into future guideline documents.The subcommittees were charged with preparing standards dealing wi
25、th several aspects of thein-service inspection and maintenance of pressure equipment and piping. The Inspection PlanningStandard provides guidance on the preparation of a risk-based inspection plan. Defects that areidentified are then evaluated, when appropriate, using the procedures provided in the
26、 Fitnessfor Service. Finally, if it is determined that repairs are required, guidance on repair proceduresis provided in the Repair of Pressure Equipment and Piping Standard. These documents are invarious stages of preparation.None of these documents are Codes. They provide recognized and generally
27、accepted goodpractices that may be used in conjunction with Post-Construction Codes, such as API 510, API 570,and NB-23, and with jurisdictional requirements.The first edition of ASME PCC-1, Guidelines for Pressure Boundary Bolted Flange Joint Assembly,was approved for publication in 2000. ASME PCC-
28、12000 was approved by the American NationalStandards Institute (ANSI) as an American National Standard on November 15, 2000.The first edition of ASME PCC-2, Repair of Pressure Equipment and Piping, was approved forpublication in 2004. This revision was approved by ANSI as an American National Standa

30、 for interpre-tations and revisions of the rules of this Standard and develop new rules if dictated by technologi-cal development. The Committees activities in this regard are limited strictly to interpretationsof the rules or to the consideration of revisions to the present rules on the basis of ne
31、w data ortechnology. As a matter of published policy, ASME does not “approve,” “certify,” “rate,” or“endorse” any item, construction, proprietary device, or activity, and, accordingly, inquiriesrequiring such consideration will be returned. Moreover, ASME does not act as a consultant onspecific engi
32、neering problems or on the general application or understanding of the rules. If,based on the inquiry information submitted, it is the opinion of the Committee that the inquirershould seek professional assistance, the inquiry will be returned with the recommendation thatsuch assistance be obtained.A
33、n inquiry that does not provide the information needed for the Committees full understandingwill be returned.REQUIREMENTSInquiries shall be limited strictly to interpretations of the rules or to the consideration ofrevisions to the present rules on the basis of new data or technology. Inquiries shal
34、l meet thefollowing requirements:(a) Scope. Involve a single rule or closely related rules in the scope of the standard. An inquiryletter concerning unrelated subjects will be returned.(b) Background. State the purpose of the inquiry, which may be either to obtain an interpretationof rules of this S
35、tandard, or to propose consideration of a revision to the present rules. Provideconcisely the information needed for the Committees understanding of the inquiry, being sureto include reference to the applicable Part, Article, Edition, Addenda, paragraphs, figures, andtables. If sketches are provided
36、, they shall be limited to the scope of the inquiry.(c) Inquiry Structure(1) Proposed Question(s). The inquiry shall be stated in condensed and precise question for-mat, omitting superfluous background information, and, where appropriate, composed in sucha way that “yes” or “no” (perhaps with provis
37、os) would be an acceptable reply. The inquirystatement should be technically and editorially correct.(2) Proposed Reply(ies). Provide a proposed reply stating what the inquirer believes that thestandard requires.If in the inquirers opinion, a revision to the standard is needed, recommended wording s
38、hallbe provided in addition to information justifying the change.SUBMITTALInquiries shall be submitted in typewritten form; however, legible handwritten inquiries willbe considered. They shall include the name and mailing address of the inquirer, and may eitherbe sent by email to SecretaryPCCasme.or
