COPYRIGHT American Society of Mechanical Engineers Licensed by Ination Handling Services COPYRIGHT American Society of Mechanical Engineers Licensed by Ination Handling Services FOREWORD This Foreword is not part of ASME B16.24-1991. The development of the first Bronze Flanged Standard was started i n 1910 to eliminate the confusion prevailing in the trade with respect to bronze flange dimensions and service ratings. The work culminated and was published in 1914 under the title “1914 Brass Standard Flange Dimensions’’ for 150 and 250 lb steam pressures. This was superseded in 1928 by the Manufacturers Standardization Society of Valves and Fittings Industry MSS “Standard Practice” SP-2 which contained changes to pro- vide interchangeability with the American Cast-Iron Flange Standards for 125 lb and 250 lb steam pressures, Subsequent revisions were issued i n 1930 and 1936. In the latter a new column of thickness for 300 lb flanges was added. In the 1937 edition, illustrations and dimensions of bronze flanged fittings were added. This was edited and reprinted i n 1943 to make it con in effect to U.S. Department of Commerce, National Breau of Standards, Simplified Practice Recommendation R- 183-42 and to the War Production Board Limitation Order G252, dated January 23, 1943. In the 1946 edition, the pressure-temperature ratings were added for the 150 lb and 300 lb standards and the dimensions for and reference to the 250 lb standard were omitted. Limitation Order G252 was cmcelIed on April 28, 1945. The period of Gov- ernment prohibition of manufacture and civilian use of the 250 lb standard, during the life of Order G252, caused no hardship on the part of either the manufacturer or the consumer, indicating that this pressure class in bronze products does not warrant being recognized as a standard. This standard which has been kept up-to-date and in constant use since 1910, was reviewed and reaffirmed in 1949. In October, 1951, MSS presented it to SectionaI Com- mittee B16 on Pipe Franges and Flanged Fittings for review and possible approval as an American Standard. Following approval o f the sectional committee and sponsor organizations, it was pre- sented to the American Standards Association ASA, now the American National Stan- dards Institute ANSI, for approval and designation as an American Standard. This was granted on February 27, 1953. In 1961, following the organization of Subcommittee No. 11 now J, work was begun on revision of the 1953 edition. Chief among the changes recommended was the deletion of reference to brass. This resulted from an action by the ASTM of redefining the alloys which could properly be called bronze. Several other changes which brought the standard up-to-date were also approved by the Sectional Committee and sponsor organizations, with approval designation as an American Standard being granted on July 2 0 , 1962. Subcommittee J, in keeping with regulations of ANSI began a review of the document in 1969. Only minor changes were found necessary. Among these were the presentation of ratings in tabular , and the gasket retaining grooves being made permissible rather than recommended. Final approval to the changes was granted by ANSI on January 27, 1971. A revision was undertaken i n 1977 and several changes were proposed, Chief among ... 111 COPYRIGHT American Society of Mechanical Engineers Licensed by Ination Handling Services COPYRIGHT American Society of Mechanical Engineers Licensed by Ination Handling Services these was the addition of metric equivalents and the elimination of the optional gasket retaining grooves. In addition, the standard was extensively revised editorially.

This includes any maximum tem- perature limitation, or rule governing the use of a material at low temperature, or provisions for oper- ating at a pressure exceeding the pressure-temper- ature ratings in this Standard. 1.3 Units of Measurement U.S. customay units are the standard. For con- u 1 in. 25.4 mm version to metric units use the foIlowing the dimensions prescribed in Tables 3, 4, 5, and 6. The tabulated pressuretemperature ratings shown in Table 1 apply to the materials designated i n para. 5.2.3 and to the dimensions prescribed in ASME/ ANSI B16.5. All ratings are independent of the con- tained fluid and are the maximum non-shock pres- sures at the tabulated temperatures. Pressure ratings at temperatures intermediate to those tabulated may be obtained by linear interpolation. 2.2 Ratings of Flanged Joints Ratings in this Standard apply to flanged joints which con to the limitations on bolting in paras. 5.4 and 8a, and on gaskets in paras. 5.5 and 8b and which are made up in accordance with good practice for alignment and assembly. Use of the rat- ings for flanged joints not coning to these limi- tations is the sole responsibility of the user. Requirements for alignment and assembly of joints and consideration of leakage due to forces and mo- ments developed in the connected piping or equip- ment are not covered in this Standard. if the two flanges in a flanged joint do not. have the same pres- sure-temperature ratings, the rating of the joint at any temperature is the lower of the two flange ratings at that temperature. 2.3 Rating Temperature bj 1 psi 0.069 bar 6.9 kPa The temperature shown for a corresponding pres- C O F 13C 32 sure rating is the temperature of the pressure-con- taining shell of the flange or flanged fitting. In general, this temperature is the same as that of the ing to a temperature other than that of the contained fluid is the responsibility of the user, subject to the The tabulated pressure-temperature ratings applicable code or regulation. For any temperature shown in Tables 1 and 2 apply to the materials des- below - 20F, the rating shall be no greater than the ignated in paras. 5.2.1, 5.2.2, 5.3.1, and 5.3.2, and to rating for -20F. 2 PRESSURE-TEMPERATURE RATINGS . contahed fluid.

System testing at higher pressures is the re- sponsibility of the user, subject to the requirements of the applicable code or regulation. 3 SIZES AND OF DESIGNATING OPENINGS 3.1 The size of a regular flange or fitting is identi- fied by the corresponding nominal’ pipe size, NPS. 3.2 Reduced fittings shall be designated by the size of the openings in their proper sequence as indi- cated in Fig. 1. 4 MARKING 4.1 General Except as modified herein, flanges and flanged fit- 4.1.1 Name.
