14、 ASME International Provided by IHS under license with ASME Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-FOREWORDThe Sectional Committee on the Standardization of Pipe Flanges and Fittings, B16, organizedin 1920 under the procedure of the American Standards Asso

15、ciation (ASA) appointed a subgroupof Subcommittee 3 (now Subcommittee F) to initiate the standardization of welding fittings inMay 1937. The first meeting of this group was held later that month, and at its meeting inDecember 1938, in New York, it was agreed to undertake the standardization of dimen

16、sions ofsocket-welding fittings and to refer this project to a new drafting subgroup. One of the mostimportant dimensions of this type of fitting requiring standardization was considered to be thedimension from the centerline of the fitting to the bottom of the socket, since from the standpointof th

17、e designing engineer, this dimension governs the location of adjacent pipe with referenceto the entire piping layout. Another important item for consideration was the welding filletdimensions.The drafting subgroup held meetings in Chicago, Detroit, and New York in March 1939 andMay and October 1940,

18、 respectively, and at the last named meeting, the completed draft of theproposed standard was discussed, and further revisions were suggested. When applied to theSeptember 1940 draft, these changes produced the May 1941 draft, which was prepared fordistribution to industry for criticism and comment.

19、This distribution resulted in a number of helpful comments. The members of the subgroupagreed by mail that many of the changes suggested should be incorporated in the revised draft(December 1941). Progress on the approval of the standard was delayed by the war, after which,a few more changes were ad

20、ded to make the proposal acceptable to all concerned. The reviseddraft (April 1946) was then submitted to the members of the sectional committee for letterballot vote.Following the approval of the sectional committee, the proposed standard was next approvedby the sponsor bodies and presented to the

21、ASA with recommendation for approval as anAmerican Standard. This designation was given on December 9, 1946.In 1960, it was agreed that the standard needed a complete revision and simultaneously thatit should be expanded to cover threaded fittings and plugs, then covered by MSS SP-49 andSP-50. A Tas

22、k Force worked diligently for 4 years before arriving at a draft that it felt wasacceptable. They also found that ratings were outdated and eliminated the 4,000-lb classes ofthreaded fittings, assigned pressuretemperature ratings for a number of materials, and convertedthe socket-weld fitting rating

23、s to 3,000 and 6,000 lb. Following approval by the Sectional Committeeand Sponsors, ASA approval was granted on January 28, 1966.Following designation changes of ASA to ANSI and Sectional Committee to StandardsCommittee, Subcommittee 6 began consideration of changes in 1969. Early in 1972, changes i

24、nthe pressure class designations, materials, and clarification of wording were agreed upon andsubmitted for approval. This approach was granted on June 20, 1973.The work of development of the 1980 edition of B16.11 began in 1975 when the committeebegan consideration of comments and proposals for cha

25、nge that were received. The developmentprocedure was arduous in that a number of ballots were taken that elicited many additionalcomments and counter proposals. The major changes included an expanded scope for betterdefinition, requirements for conformance marking, a Nonmandatory Annex with provisio

26、ns forproof or burst testing, and the inclusion of metric equivalents. Following approval by the StandardsCommittee and Co-Secretariat, final approval by ANSI was granted on October 6, 1980.In 1982, American National Standards Committee B16 was reorganized as an ASME Committeeoperating under procedu

27、res accredited by ANSI. The 1991 edition of the standard, retitled “ForgedFittings, Socket-Welding and Threaded,” incorporated forging material listed in Table 1 of ASMEB16.34-1988, including Group 3 material that was not previously covered in B16.11. The 1991edition established U.S. Customary units

28、 as the standard. Other clarifying and editorial revisionswere made in order to improve the text. Following approval by the Standards Committee andASME, final approval by ANSI was granted on March 4, 1991.ivCopyright ASME International Provided by IHS under license with ASME Not for ResaleNo reprodu

29、ction or networking permitted without license from IHS-,-,-In 1996, metric dimensions were added as an independent but equal standard to the inch units.Following approval by the Standards Committee and ASME, this revision to the 1991 edition ofthis Standard was approved as an American National Stand

30、ard by ANSI on December 16, 1996,with the new designation ASME B16.11-1996.In 2000, the Standards Committee, ASME, and ANSI approved an addenda to this Standardto remove partial compliance fittings and nonstandard material requirements. Due to an ASMEpolicy change concerning the publishing of addend

31、a, the intended addenda changes were incorpo-rated into the 2001 edition.Threaded end street elbow requirements were incorporated into the 2004 edition. Followingapproval by the Standards Committee and ASME, the revision to the 2001 edition was approvedas an American National Standard by ANSI on Sep

32、tember 30, 2005 with the designationASME B16.11-2005.A number of technical revisions were made along with format and reference revisions, suchas material marking requirements. Following approval by the Standards Committee and ASME,this revision to the 2005 edition was approved as an American Nationa

33、l Standard by ANSI onJuly 9, 2009 with the designation ASME B16.11-2009.Suggestions for improvement of this Standard are welcome.
