This specification covers only factory-made wrought aluminum and aluminum-alloy welding fittings in contrast to field-made fittings. The aluminum or aluminum-alloy material used in the manufacture of the fittings shall be in accordance with the alloy and temper specified. The material shall be in the form of rod, bar, forgings, sheet, plate, seamless pipe or seamless tube, each of which conforms to all requirements. Forging or shaping operations may be performed by hammering, pressing, piercing, rolling, extruding, upsetting, bending, or fusion welding, or by a combination of two or more of these operations. Tension tests and hydrostatic tests shall be made to conform to the specified requirements.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers only factory-made wrought aluminum and aluminum-alloy welding fittings in contrast to field-made fittings. The term “welding fittings” applies to butt-welding or socket-end parts, such as 45° elbows, 180° return bends, 90° short radius elbows, and other types made to the dimensional standards specified by ASME B16.9 and B16.11.

Note 1—Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum-alloy.

1.2 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A1.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and heal practices and determine the applicability of regulatory limitations prior to use.
