Sectional Committee B16 to unify and further develop national standards for pipe flanges and fittings and 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. Association 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 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 published as ASA B16 9 1951 and ASA B16 9 1958 With the subgroup now desig. nated 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 and smaller sizes. NPS 1 4 and NPS 1 2 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 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 fractions were expressed as decimals but without intending higher precision and metric dimensional equiva. lents were added Provisions for step wise change of radius for NPS 3 4 long radius elbows and 180 deg returns were. introduced Following Standards Committee cosecretariat and ANSI approval the revision was published as ANSI B16 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 revised 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 which 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 appendix 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 additions 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 edition 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 the approval of the ASME B16 Standards. Committee ANSI approved ASME B16 9 2018 as an American National Standard on September 25 2018. falatghareh ir,falatghareh ir,ASME B16 COMMITTEE, Standardization of Valves Flanges Fittings and Gaskets.
