This specification covers drawn seamless aluminum-alloy tube of specified tensile properties for use in surface condensers, evaporators, and heat exchangers. The tube shall be produced by drawing an extruded tube made from hollow extrusion ingot (cast in hollow form or pierced) and extruded by use of the die and mandrel method. The tube shall be subjected to tension, leak, and expansion tests.
1.1 This specification covers aluminum-alloy ( ) drawn seamless round tube in straight lengths designated as shown in , for use in surface condensers, evaporators, and heat exchangers.
Note 1: Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
Note 2: For drawn seamless tubes used in general applications, see Specifications and ; for extruded tubes see Specifications and ; for seamless pipe and seamless extruded tube used in pressure applications see Specification ; and for structural pipe and tube see Specification .
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System alloy designations are those of preceded by A9, for example, A91060 for aluminum 1060, in accordance with Practice .
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see .
1.4 This specification is the inch-pound companion to Specification ; therefore, no SI equivalents are presented in the specification.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
