27、ittee on the Standardization of Pipe Flanges and Fittings, B16, organized in 1920 under the procedure of the American Standards Association (ASA), appointed a subgroup of Subcommittee 3 (now Subcommittee F) to initiate the standardization of welding fittings in May 1937. The first meeting of this gr

28、oup was held later that month, and at its meeting in December 1938, in New York, it was agreed to undertake the stan- dardization of dimensions of socket-welding fittings and to refer this project to a new drafting subgroup. One of the most important dimensions of this type of fitting requiring stan

29、dardization was considered to be the dimension from the centerline of the fitting to the bottom of the socket, since from the standpoint of the designing engineer, this dimension governs the location of adjacent pipe with reference to the entire piping layout. Another important item for consideratio

30、n was the welding fillet dimensions. The drafting subgroup held meetings in Chicago, Detroit, and New York in March 1939 and May and October 1940, respectively, and at the last named meeting, the completed draft of the proposed standard was discussed, and further revisions were suggested. When appli

31、ed to the September 1940 draft, these changes produced the May 1941 draft, which was prepared for distribution to industry for criticism and comment. This distribution resulted in a number of helpful comments. The members of the subgroup agreed by mail that many of the changes suggested should be in

32、corporated in the revised draft (December 1941). Progress on the approval of the standard was delayed by the World War II, after which, a few more changes were added to make the proposal acceptable to all concerned. The revised draft (April 1946) was then submitted to the members of the sectional co

33、mmittee for letter ballot vote. Following the approval of the sectional committee, the proposed standard was next approved by the sponsor bodies and presented to the ASA with recommendation for approval as an American Standard. This designation was given on December 9, 1946. In 1960, it was agreed t

34、hat the standard needed a complete revision and simultaneously that it should be expanded to cover threaded fittings and plugs, then covered by MSS SP-49 and SP-50. A Task Force worked diligently for four years before arriving at a draft that was acceptable. They also found that ratings were outdate

35、d and eliminated the 4,000-lb classes of threaded fittings, assigned pressure-temperature ratings for a number of materials, and converted the socket- weld fitting ratings to 3,000 and 6,000 lb. Following approval by the Sectional Committee and Sponsors, ASA approval was granted on January 28, 1966.

36、 Following designation changes of ASA to ANSI and Sectional Committee to Standards Committee, Subcommittee 6 began consideration of changes in 1969. Early in 1972, changes in the pressure class designations, materials, and clar- ification of wording were agreed upon and submitted for approval. This

37、was granted on June 20, 1973. The work of development of the 1980 edition of B16.11 began in 1975 when the committee began consideration of comments and proposals for change that were received. The development procedure was arduous in that a number of ballots were taken that elicited many additional

38、 comments and counterproposals. The major changes included an expanded scope for better definition, requirements for conformance marking, a Nonmandatory Annex with provisions for proof or burst testing, and the inclusion of metric equivalents. Following approval by the Standards Committee and Co- Se

39、cretariat, final approval by ANSI was granted on October 6, 1980. In 1982, American National Standards Committee B16 was reorganized as an ASME Committee operating under procedures accredited by ANSI. The 1991 edition of the standard, retitled “Forged Fittings, Socket- Welding and Threaded, ” incorp

40、orated forging material listed in Table 1 of ASME B16.34-1988, including Group 3 material that was not previously covered in B16.11. The 1991 edition established U.S. Customary units as the standard. Other clarifying and editorial revisions were made to improve the text. Following approval by the St

41、andards Committee and ASME, final approval by ANSI was granted on March 4, 1991. 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 of this Standard was approved as an

42、 American National Standard 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 Standard to remove partial compli- ance fittings and nonstandard material requirements. Due to an ASME policy change conce

43、rning the publishing of addenda, the intended addenda changes were incorporated into the 2001 edition. vThreaded end street elbow requirements were incorporated into the 2004 edition. Following approval by the Standards Committee and ASME, the revision to the 2001 edition was approved as an American

44、 National Standard by ANSI on September 30, 2005 with the designation ASME B16.11-2005. A number of technical revisions were made along with format and reference revisions, such as material marking requirements. Following approval by the Standards Committee and ASME, the revision to the 2005 edition

45、 was approved as an American National Standard by ANSI on July 9, 2009 with the designation ASME B16.11-2009. This revision was approved by the American National Standards Institute on December 2, 2011. In this 2016 Edition, provisions have been made to update verbiage and readings. Following the ap

46、proval by the ASME B16 Standards Committee, approval as an American National Standard was given by ANSI on October 21, 2016, with the new designation ASME B16.11-2016. viASME B16 COMMITTEE Standardization of Valves, Flanges, Fittings, and Gaskets (The following is the roster of the Committee at the
