25、ASMENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-FOREWORD Ring-joint gaskets and grooves probably originated in the boiler field, where they were used in various forms for manhole covers, autoclaves, and other closures; however, it was in the oil industry (both
26、in the production and refining of oil) that they received the greatest recognition and were developed into their present form. Their use expanded steadily as temperatures and pressures were increased in steam plants. Tests examining their application in flanges and valves were conducted as early as
27、1928. In June 1936, the American Petroleum Institute (API) issued Tentative Standard 543-3 on Ring-Joints for Steel Flanges and Flange Unions for use with API Tubular Goods. This standard was known as API Specification 6B, Ring-Joint Flanges. Following the acceptance of ring-joints for flanges and v
28、alves by API and the issuance of their standard, ASA B16e on Steel Pipe Flanges and Flanged Fittings was revised to include them, and the 1939 edition included standard dimensions for a full line of ring-joint flanges based on the API standard. Development work continued, and API formulated Standard
29、 6E, Specification for Wellhead Equipment, which included ring-joints not covered in ASA B16e-1939. In 1949, the American Standards Association (ASA), Sectional Committee B 16, Subcommit- tee 3, Steel Flanges and Flanged Fittings, assembled the available information on ring-joint gaskets into a sing
30、le standard. ASA approval was granted on April 30, 1952, with the designation ASA B 16.20-1 952. Ring gaskets for Class 900 (900 Ib at that time) in sizes NPS 26 through 36 were added, and ASA approval was granted on April 30, 1952. An updated version was submitted, and ASA approval was granted on A
31、pril 4, 1955, with the designation ASA B i 6.20- 1955. The standard was reviewed, and reaffirmation approval was granted by the ASA on April 25, 1963. The standard was reviewed, and reaffirmation approval was granted by the American National Standards Institute (ANSI) on April 25, 1973, with the des
32、ignation of an American National Standard. API requested that ASME convert their gasket standard, API 601, into an ASME American National Standard. As a result of that request, this edition was expanded to include requirements for spiral-wound and jacketed gaskets that were formerly listed in API 60
33、1, 7th edition, 1988. Also, ring-joint groove dimensions are not included in this edition because they are included in ASMWANSI B 16.5-1 988, titled Pipe Flanges and Flanged Fittings, and ASME B 16.47-1990, titled Large Diameter Steel Flanges. The 1993 edition was approved by the BI6 Standards Commi
34、ttee. Following approval by ASME, approval by ANSI was given on January 22, 1993, with the designation ASME In the 1998 edition of ASME B16.20, reference standards are updated, a quality system program annex is added, inner ring inside diameters for spiral-wound gaskets are revised, and several edit
35、orial revisions are made. Following approval by ASME B 16 Subcommittee B and the BI6 Main Committee, ANSI approved this American National Standard on November 20, 1998. Requests for interpretations or suggestions for revision should be sent to The American Society of Mechanical Engineers; Secretary,
