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

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
