16、further develop national standards for pipe flanges and fittings fand later, for valves, gaskets, and valve actuators). Cosponsors of the B16 Committee were The American Society of Mechanical Engineers (ASME), the Heating and Piping Contractors National Association now the Mechanical Contractors Ass

17、ociation of America (MCAA), and the Manufacturers Standardization Society of the Valve and Fittings Industry (MSS). Cosponsors were later designated as cosecretariat organizations.Standardization of welding fittings was initiated in 1937 by a subgroup (designated Subgroup 6) of Subcommittee 3. After

18、 consideration of several drafts, a standard was approved by the Committee, cosponsors, and ASA, and published with the designation ASA B16.9-1940.Revisions were made in 1950 and 1955 to add sizes up to NPS 24 and to complete coverage of fittings in some sizes. These revisions were approved and publ

19、ished as ASA B16.9-1951 and ASA B16.9-1958. With the subgro叩 now designated Subcommittee 6 (later Subcommittee F), further revisions were begun to clarify the intent of the Standard, to add angularity tolerances, and to include fittings of different types (long radius reducing elbows and crosses) an

20、d smallersizes (NPS % and NPS %). This revision was published as ASA B16.9-1964 after ASA approval.After reorganization of ASA, first as the United States of America Standards Institute (USASI), then as the American National Standards Institute (ANSI), with the Sectional Committee being redesignated

21、 as an American National Standards Committee, another revision increasing the size range to NPS 48 and revising the text for clarity was approved and published as ANSI B16.9-1971.In 1975, Subcommittee F began a major revision to bring the standard up to date with current practice and usage. Common f

22、ractions were expressed as decimals (but without intending higher precision) and metric dimensional equivalents were added. Provisions for step-wise change of radius for NPS % long radius elbows and 180-deg returns were introduced. Following Standards Committee, cosecretariat, and ANSI approval, thp

23、 revision was published as ANSI R16.9- 1978. It was updated by a corrective addendum, B16.9a-1981, issued in February 1982.In 1982, American National Standards Committee B16 was reorganized as an ASME Committee operating under procedures accredited by ANSI. In ASME/ANSI B16.9-1986, the text was revi

24、sed and inch dimensions were established as the standard.In 1991, the Subcommittee reviewed the Standard and made a number of revisions that were included in ASME B16.9- 1993. Dimensions for short pattern lap joints were also added.In ASME B16.9-2001, short radius elbows and returns were added, whic

25、h included all dimensions and tolerances of ASME B16.28-1994. Metric units were provided as an independent but parallel alternative standard to U.S. Customary units. U.S. Customary units were moved into parentheses or separate tables in Mandatory Appendix I. In addition, a Quality System Program app

26、endix was added.In 2003, the Subcommittee reviewed the Standard and made a number of revisions. The scope of the Standard was changed to permit fabricated lap joint stub ends employing circumferential or intersection welds.In 2006. the Subcommittee reviewed the Standard and made a number of addition

27、s and revisions. Segmental elbow requirements were added, as were 3D radius elbow dimensions. Reference documents were updated.In 2012. the Subcommittee reviewed the Standard and made numerous revisions to the design proof test in section 9 and updated the references in Mandatory Appendix II.This ed

28、ition adds more specific descriptions of acceptable design methods, revises the requirements for the design proof test, and updates the references. In addition, the U.S. Customary tables in Mandatory Appendix I have been merged with the Metric tables and all tables have been redesignated. Following

29、the approval of the ASME B16 Standards Committee, ANSI approved ASME B16.9 2018 as an American National Standard on September 25, 2018.9ASME B16 COMMITTEEStandardization of Valves, Flanges, Fittings, and Gaskets(The following is the roster of the Committee at the time of approval of this Standard.)S
