Every attempt was made to standardize those dimen

21、sions that existed within the industryfor the materials covered by ANSI B16.5.Prompted by suggestions from committee members, the task force was authorized to increasethe size range to NPS 60. The first draft was developed in December 1982 to include Class 75through Class 1500 for the size range NPS

22、 26 through NPS 60. Flange dimensions were basedon the Manufacturers Standardization Society, Standard Practice (MSS SP) 44 flanges, except forClass 75 flanges that are ANSI/API 605 flanges.At the request of the American Petroleum Institute (API), flange dimensions, in accordancewith the API Standar

23、d 605, were included in the 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 Classes 150 and 300 and for sizes NPS 36 and smaller for classes higherthan Class 300 are not compatible with

24、 the MSS SP-44 flanges. Thus, 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 accord

25、ance with ANSI B16.5.In 1982, 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 w

26、as given by ANSI on June 12, 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

27、 Series B flanges,and included 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.In 2006, several revisi

28、ons were made, including use of metric units as primary units, withU.S. Customary units in either parenthetical or separate forms. Mandatory Appendix I wasprovided after the main text for convenience to cover ratings and dimensions in U.S. Customaryunits. Inch dimension bolt holes were retained for

29、flanges manufactured to metric dimensionsto avoid fit up problems. Development of metric dimensions was done to reflect the intendedprecision of the dimension rather than by numerical conversion. For some materials pressuretemperature ratings were revised to reflect revisions to material strength pr

30、operties (tensile andyield) listed in the ASME Boiler and Pressure Vessel Code, Section II. Some materials wereassigned to different rating tables in order to minimize changes to ratings for commonly usedmaterials. Following the approvals of the Standards Committee and ASME, approval for therevised

31、edition was granted by the American National Standards Institute on November 6, 2006.In the 2011 edition, the References section has been revised to cover the requirements of materialspecification editions other than those listed in Mandatory Appendix III. Additionally, thisStandard was updated in r

32、egard to the latest revisions to ASME B16.5.All requests for interpretation or suggestions for revisions should be sent to the Secretary,B16Committee,TheAmerican SocietyofMechanicalEngineers,ThreePark Avenue,NewYork,NY10016-5990.

SeriesB specifies flange dimensionsfor com-pact flanges that, in most cases, have smaller bolt circlediameters than Series A flanges. These two series offlanges are, in general, not interchangeable. The usershould recognize that some flanged valves, equipmentbolted between flanges, and flanged equipment may becompatible with only one series of these flanges.1.3 Ref
