FOREWORD
(This Foreword is not part of ASME B16.36-1996.)
激情文学88August of 1956 marked the first recorded correspondence noting the lack of standardization for orifice flanges. There were, and still are, veral codes for the performance and calibration of orifice flanges, but there had been no standardization of the flanges themlves. Over the ensuing 3 years, correspondence
continued among the Instrument Society of America, American Gas Association, and the B16 Standards Committee.
On December 3, 1959, Subcommittee 3 (now Subcommittee C) of B16 authorized the appointment of a Task Force to undertake drafting of a standard. Although the initial work progresd smoothly, a controversy developed over the standard size of taps to be specified for the flanges. This required many years to resolve. It was finally achieved in 1973 with the issuance of a draft from the Task Force. Comments and objections to this draft from members of Subcommittee C were resolved, and a redraft was approved by the Subcommittee late in 1974. The B16 Standards Committee was balloted in the spring of 1975 and approval was gained. Comments from B16 members from the gas industry requested that the Class 400 orifice flange be included, and the B16 Subcommittee C agree
d to consider this for a possible addendum. The Standard was approved by ANSI on August 15, 1975.
On April 30, 1979, an addenda was issued which added Class 400 flanges and Annex B covering reference documents and organizations.
In 1982, American National Standards Committee B16 was reorganized as an ASME Committee operating under procedures accredited by ANSI. In the 1988 edition, figures were added to illustrate jack bolts and comer taps, metric units have been omitted, and references to other standards have been updated. Following approval by the B16 Main Committee and the ASME Supervisory Board, the Standard was approved as an American National Standard by ANSI on February 18, 1988.
This 1996 Edition adds angular meter taps for ring joint flanges in sizes not previously covered and includes veral other revisions. Following approval by the B16 Main Committee and the ASME Supervisory Board, this Standard was approved as an American National Standard by ANSI on November 6, 1996. Requests for interpretations or suggestions for revisions should be nt to the Secretary, B16 Committee, The American Society of Mechanical Engineers, United Engineering Center, 345 East 47th Street, New York, NY 10017.
