ASTM B234M

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. Scope

1.1 This specification covers aluminum-alloy (Note 0) drawn seamless round tube in straight lengths designated as shown in the , for use in surface condensers, evaporators, and heat exchangers. Note 0Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.

For drawn seamless tubes used in general applications, see Specification B 210M; for extruded tubes see Specification B 221M; for seamless pipe see Specification B 241/B 241M; and for structural pipe and tube see Specification B 429.

This specification is the metric counterpart of Specification B 234.

1.2 Alloy and temper designations are in accordance with ANSI H35.1M. The equivalent Unified Numbering System alloy designations are those of preceded by , for example, A91060 for aluminum 1060, in accordance with Practice E 527.

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

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 health practices and determine the applicability of regulatory limitations prior to use.
