22、cense from IHS-,-,-FOREWORDIn November 1980, a task force was appointed within Subcommittee C of the American NationalStandards (ANSI) B16 Committee to develop a standard for pipe flanges in size NPS 26 throughNPS 48. Every attempt was made to standardize those dimensions that existed within the ind
23、ustryfor the materials covered by ANSI B16.5.Prompted by suggestions received from committee members, the task force was authorized toincrease the size range to NPS 60. The first draft was developed in December 1982 to includeClass 75 through Class 1500 for the size range NPS 26 through NPS 60. Flan
24、ge dimensions werebased on the Manufacturers Standardization Society Standard Practice (MSS SP) 44 flanges, exceptfor Class 75 flanges that are ANSI/API 605 flanges.At the request of the American Petroleum Institute (API), flange dimensions, in accordancewith the API Standard 605, were included in t
25、he subsequent drafts. Class 1500 flanges weredeleted due to a lack of interest in using large size flanges in that pressuretemperature rating.The API-605 flanges for Class 150 and 300 and for sizes NPS 36 and smaller for classes higherthan Class 300 are not compatible with the MSS SP-44 flanges. Thu
26、s, the MSS SP-44 flanges aredesignated as Series A flanges and the API-605 flanges are designated as Series B flanges in thisStandard. Materials covered in this Standard are as in ANSI B16.5, except nickel base alloys areexcluded. Pressuretemperature ratings are in accordance with ANSI B16.5.In 1982
27、, American National Standards Committee B16 was reorganized as the American Societyof Mechanical Engineers (ASME) B16 Committee operating under procedures accredited by ANSI.Following approval by the Standards Committee and ASME, approval as an American NationalStandard was given by ANSI on June 12,
28、 1990.The 1996 Edition allowed flanges marked with more than one material grade or specification,revised flange face finish requirements, revised pressuretemperature ratings for several materialgroups, added permissible flange facing imperfections, added blind flanges for Series B flanges,and includ
29、ed several other revisions. Following approval by the Standards Committee and ASME,Boiler and Pressure Vessel Committee, ANSI approved the previous edition as an AmericanNational Standard on October 3, 1996 with the new designation ASME B16.47-1996.This 2006 Edition is presented in metric units, as
30、primary units, with U.S. Customary units ineither parenthetical or separate forms. Mandatory Appendix I has been provided after the maintext for convenience to cover ratings and dimensions in U.S. Customary units. Inch dimensionbolt holes were retained for flanges manufactured to metric dimensions t
31、o avoid fit up problems.Development of metric dimensions was done to reflect the intended precision of the dimensionrather than by numerical conversion. For some materials pressuretemperature ratings have beenrevised to reflect revisions to material strength properties (tensile and yield) listed in
32、the ASMEBoiler and Pressure Vessel Code, Section II. Some materials have been assigned to different ratingtables in order to minimize changes to ratings for commonly used materials.All requests for interpretation or suggestions for revisions should be sent to the AdministrativeSecretary B16, The Ame

41、m IHS-,-,-CORRESPONDENCE WITH THE B16 COMMITTEEGeneral. ASME Standards are developed and maintained with the intent to represent theconsensus of concerned interests. As such, users of this Standard may interact with the Committeeby requesting interpretations, proposing revisions, and attending Commi
42、ttee meetings. Corre-spondence should be addressed to:Secretary, B16 Standards CommitteeThe American Society of Mechanical EngineersThree Park AvenueNew York, NY 10016-5990As an alternative, inquiries may be submitted via e-mail to: SecretaryB16asme.org.Proposing Revisions. Revisions are made period
43、ically to the Standard to incorporate changesthat appear necessary or desirable, as demonstrated by the experience gained from the applicationof the Standard. Approved revisions will be published periodically.The Committee welcomes proposals for revisions to this Standard. Such proposals should beas
44、 specific as possible, citing the paragraph number(s), the proposed wording, and a detaileddescription of the reasons for the proposal, including any pertinent documentation.Interpretations. Upon request, the B16 Committee will render an interpretation of any require-ment of the Standard. Interpreta
45、tions can only be rendered in response to a written request sentto the Secretary of the B16 Standards Committee.The request for interpretation should be clear and unambiguous. It is further recommendedthat the inquirer submit his/her request in the following format:Subject: Cite the applicable parag
46、raph number(s) and the topic of the inquiry.Edition: Cite the applicable edition of the Standard for which the interpretation isbeing requested.Question: Phrase the question as a request for an interpretation of a specific requirementsuitable for general understanding and use, not as a request for a
47、n approvalof a proprietary design or situation. The inquirer may also include any plansor drawings, which are necessary to explain the question; however, theyshould not contain proprietary names or information.Requests that are not in this format will be rewritten in this format by the Committee pri
48、orto being answered, which may inadvertently change the intent of the original request.ASME procedures provide for reconsideration of any interpretation when or if additionalinformation that might affect an interpretation is available. Further, persons aggrieved by aninterpretation may appeal to the
49、 cognizant ASME Committee or Subcommittee. ASME does not“approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity.Attending Committee Meetings.
