2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers only factory-made wroughtaluminum and aluminum-alloy welding fittings in contrast tofield-m
3、ade fittings. The term “welding fittings” applies tobutt-welding or socket-end parts, such as 45 elbows, 180return bends, 90 short radius elbows, and other types made tothe dimensional standards specified by ASME B16.9 andB16.11.NOTE 1Throughout this specification use of the term alloy in thegeneral
4、 sense includes aluminum as well as aluminum-alloy.1.2 For acceptance criteria for inclusion of new aluminumand aluminum alloys in this specification, see Annex A1.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to
5、SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and heal practices and determ

35、merciallysound. Any requirement not so covered is subject to negotia-tion between producer and purchaser.9. Tension Tests9.1 Tension tests of the finished fittings are not required,unless otherwise agreed upon between the producer and thepurchaser and so specified in the order. When tension tests ar
36、emade, methods of test, test specimens, and sampling frequencyshall be agreed upon between the producer and the purchaser.10. Hydrostatic Tests10.1 Welding fittings shall be capable of withstanding aninternal hydrostatic pressure, calculated according to the fol-lowing equation, without developing l
37、eaks:P 5 2St/D (1)where:P = maximum hydrostatic test pressure (gage), psi (MPa)(Note 3),S = 0.50 times the minimum specified yield strength of thedesignated material, psi (MPa),t = nominal wall thickness, in. (mm) of designated sched-ule number (Note 4), andD = outside diameter at bevel, in. (mm).10
38、.2 Hydrostatic acceptance tests shall be made only whenagreed upon between the producer and the purchaser and sospecified in the order.NOTE 3See Appendix X1.NOTE 4For nominal wall thicknesses corresponding to schedulenumbers, see Specification B 241/B 241M.11.
