Scope *1.1 This specification covers only fac
3、tory-made wroughtaluminum and aluminum-alloy welding fittings in contrast tofield-made 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.

They may be specifiedwhen desired. The so-called “modified vee” end prepara
33、tion described inAWS D10.7 is one example.8.2 Unless otherwise specified, the material shall be sup-plied in the mill finish and shall be uniform as defined by therequirements of this specification and shall be commerciallysound.

Hydrostatic Tests10.1 Welding fittings shall be capable of withstanding aninternal hydrostatic pressure, calculated accordi
36、ng to the fol-lowing equation, without developing leaks: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 (Not

46、esentative of the inspection lot and when no other samplingplan is provided or approved by the purchaser through thecontract or purchase order, at least two additional specimensshall be selected to replace each test specimen that failed. Allspecimens so selected for retest shall meet the requirement

Identification Marking of Product13.1 The producers name or trademark, the size andschedule number, and the material shall be stamped (Note 5),stenciled, or otherwise suitably marked on each fitting. Whenthe size does not

Each fitting shall be marked with the alloydesignation listed in Table 1. On wall thicknesses thinner thanSchedule 40, no stamps or other indented marking shall beused.NOTE 5If steel stamps are used, care should be taken so that themarking is not deep enough to cause cracks or to reduce the wall thicknessof the fittings below the minimum allowed.14.
