14、d began in 1910 to eliminate the confusionprevailing in the trade with respect to bronze flange dimensions and service ratings. The workculminated and was published in 1914 under the title “1914 Brass Standard Flange Dimensions”for 150-lb and 250-lb (now Class 150 and Class 250) steam pressures.This
15、 was superseded in 1928 by the Manufacturers Standardization Society of Valves andFittings Industry (MSS) “Standard Practice” SP-2, which contained changes to provide inter-changeability with the American Cast-Iron Flange Standards for 125-lb (now Class 125) andClass 250 stream pressures. Subsequent
16、 revisions were issued in 1930 and 1936. In the latter, anew column of thickness for 300-lb (now Class 300) flanges was added.In the 1937 edition, illustrations and dimensions of bronze-flanged fittings were added. Thiswas edited and reprinted in 1943 to conform to the U.S. Department of Commerce, N
17、ationalBureau of Standards, Simplified Practice Recommendation R-183-42, and to the War ProductionBoard Limitation Order L-252, dated January 23, 1943.In the 1946 edition, the pressuretemperature ratings were added for the Class 150 and Class 300standards and the dimensions for that reference to the
18、 Class 250 standard were omitted. LimitationOrder L-252 was cancelled on April 28, 1945. The period of government prohibition of manufactureand civilian use of the Class 250 standard (during the life of Order L-252) caused no hardshipon the part of either the manufacturer or the consumer, indicating
19、 that this pressure class inbronze products did not warrant being recognized as a standard.This Standard was reviewed and reaffirmed in 1949. In October 1951, MSS ceded it to SectionalCommittee B16 on Pipe Flanges and Flanged Fittings for review and possible approval as anAmerican Standard.Following
20、 approval of the sectional committee and sponsor organizations, it was sent to theAmerican Standards Association (ASA), now the American National Standards Institute (ANSI),for approval and designation as an American Standard. This was granted on February 27, 1953.In 1961, following the organization
21、 of Subcommittee No. 11 (now Subcommittee J), the 1953edition was revised. Chief among the changes recommended was the deletion of reference tobrass. This resulted from an action of ASTM redefining the alloys that could properly be calledbronze. Several other changes that brought the standard up to
22、date were also approved by theB16 Committee, with approval designation as an American Standard being granted onJuly 20, 1962.Subcommittee J, in keeping with regulations of ANSI, reviewed the standard in 1969. Onlyminor changes were made. Among these were the presentation of pressuretemperature ratin
23、gsin tabular form, and the gasket-retaining grooves being made permissible rather than recom-mended. Final approval of the changes was granted by ANSI on January 27, 1971.A revision was undertaken in 1977, and several changes were proposed. Foremost among thesewas the addition of metric equivalents
24、and the elimination of the optional gasket-retaininggrooves. In addition, the standard was extensively revised editorially. Following approvals bySubcommittee J and the Standards Committee, ANSI granted its approval on June 26, 1979.In 1982, the American National Standard Committee B16 was reorganiz
25、ed as anASME Committee, operating under procedures accredited by ANSI.In 1991, the scope of the standard was changed from bronze pipe flanges and fittings to castcopper alloy flanges and flanged fittings, and it was expanded to include class designations 150,300, 600, 900, 1500, and 2500. The 1991 e
26、dition also established U.S. Customary units as thestandard, and editorial revisions were made to improve the text. Following approval by theStandards Committee and ASME, this edition of the standard was approved as an AmericanNational Standard by ANSI on February 1, 1991, with the new designation A
27、SME B16.24-1991and the new title “Cast Copper Alloy Pipe Flanges and Flanged Fittings.”In 2001, the standard was revised to include Nonmandatory Appendix A, Quality SystemProgram. Editorial revisions were made for clarification. Following approval by the B16 StandardsivCommittee and the ASME Supervi
28、sory Board, this Standard was approved as an AmericanNational Standard by ANSI on October 24, 2001.In the 2006 edition, metric units became the primary reference units while maintainingU.S. Customary units in either parenthetical or separate forms. Requirements for Class 400 flangeswere omitted from
29、 the Standard. In addition, several editorial revisions were made for clarity.Following approval by the Standards Committee and the ASME Board, ASME B16.24-2006, CastCopper Alloy Pipe Flanges and Flanged Fittings: Classes 150, 300, 600, 900, 1500, and 2500 wasapproved as an American National Standar
30、d by ANSI on November 9, 2006.In this edition, references to ASME standards were revised to no longer list specific edition years;the latest edition of ASME publications apply unless stated otherwise. Materials manufactured toother editions of the referenced ASTM standards have been permitted to be
31、used to manufacturefittings meeting the requirements of this Standard as long as the fitting manufacturer verifiesthe material meets the requirements of the referenced edition. Following approval by the StandardsCommittee and the ASME Board on PTCS, this revision was approved as an American National
32、Standard by ANSI on August 9, 2011 with the designation ASME B16.24-2011.Requests for interpretations or suggestions for revisions should be sent to the Secretary,B16 Committee, The American Society of Mechanical Engineers, Three Park Avenue, New York,NY 10016-5990.vASME B16 COMMITTEEStandardization

44、 SP-80.2 GENERAL2.1 Relevant UnitsThis Standard states values in both SI (Metric) andU.S. Customary units. As an exception, diameters ofbolts and flange bolt holes are expressed inU.S. Customary units only. These systems of units areto be regarded separately as standard. Within the text,the U.S. Cus
45、tomary units are shown in parentheses orin separate tables that appear in Mandatory Appendix I.The values stated in each system are not exact equiva-lents; therefore, it is required that each system of unitsbe used independently of the other. Except for the diam-eter of bolts and flange bolt holes,
46、combining valuesfrom the two systems constitutes nonconformance withthe Standard.2.2 ReferencesCodes, standards, and specifications containing provi-sions to the extent referenced herein constitute require-ments of this Standard. These references are listed inMandatory Appendix II.2.3 Quality System
47、sGuidelines relating to the product manufacturersquality system programs are described inNonmandatory Appendix A.12.4 Service ConditionsCriteria for selection of material suitable for particularfluid service are not within the scope of this Standard.2.5 User AccountabilityThis Standard cites duties
48、and responsibilities that areto be assumed by the flange or flange fitting user in thefollowing areas:(a) application(b) installation(c) system hydrostatic testing(d) operation(e) material selection2.6 Time of Purchase, Manufacture, or InstallationThe pressuretemperature ratings in this Standard are

For unused flanges or flanged fittings maintainedin inventory, the manufacturer of the flanges or flangedfittings may certify conformance to this edition, pro-vided that it can be demonstrated that all requirementsof this edition have been met. Where such componentswere installed in accordance with the pressuretempera-ture ratings of an earlier edition of this Standard, thosepressuretemperature ratings are applicable except asmay be governed by the appl
