    24、 because of the wall thickness of this equipment; (3) the need for interchangeability of equipment through the use of common drilling patterns; and (4) the fact that standards could be based on the successful usage and good service records of existing installations. A survey of water utility users i

    25、ndicated that it was desirable to maintain the outside diameter and drilling of flanged fittings and valves given in ANSI/ AWWA C500, Gate Valves for Water and Sewage Systems, and ANSI/ASME B16.1, Cast Iron Pipe Flanges and Flanged Fittings (for classes 25, 125, 250, and 800). The committee decided

    26、to follow this practice for sizes 6 in. through 48 in. (150 mm through 1,200 mm). In its extensive deliberations, the ASME/AWWA committee had available the results of special research and testing conducted by Armco Steel Corporation, Bethlehem Steel Company, and Taylor Forge and Pipe Works. The vari

    27、ous design methods and test results were given in “Steel Ring Flanges for Steel Pipe,” Bulletin 47-A (1947), from the Ameri- can Rolling Mill Company, Middletown, Ohio. The design of flanges for waterworks service, with the results of the preceding report, was published in Journal AWWA in October 19

    28、50, pp. 931944. A discussion in the paper by Taylor Forge, participants in the ASME/AWWA committee, states the reasons why a waterworks flange is not an ASME/Taylor Forge flange. Concern about high secondary stresses at the attachment, e.g., thick material to thin wall pipe, is covered here along wi

    29、th the published “Design of Wye Branches” (Journal AWWA June 1955, appendix C, pp. 581630). Beginning in 2006, a special flange task group investigated development history of the flange dimensions found within the standard. After five years of research the task group reached the following conclusion

    30、s. 1. There is no one exact stress-based design method that could reproduce the thickness values in the tables. However, it appears the ring flange thicknesses in this standard are based on using the LaTour-Barnard design procedure (ARMCO Bulletin 47-A, 1947) for ring flanges, which is based on ASME

    31、 integral flange design procedures. 2. A current design analysis was performed based on the LaTour-Barnard proposed design method (which was based on physical tests on pipes with steel ring flanges) that demonstrated comparable results. It is worthwhile to mention that the original LaTour-Barnard de

    32、sign procedure was a bending stress design methodology. 3. It has been established that flange thickness design based solely on a stress- based design procedure is incorrect. In Barnards October 1950 Journal AWWA paper he writes: “When the test results were analyzed, it became obvious that the design formulas used in establishing American Standard flange dimensions predicted fantastically high localized stresses even when the joint assembly performed satisfactorily.
