    ASTM B234

    Abstract

    This specification covers the standard for aluminum-alloy drawn seamless round tube in straight lengths proposed for use in surface condensers, evaporators, and heat exchangers. The tubes shall be manufactured by drawing an extruded tube made from hollow extrusion ingot and extruded using the die and mandrel method. Tubes shall conform to specified chemical composition 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 aluminum-alloy (Note 1) drawn seamless round tube in straight lengths designated as shown in Table 2, 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 B210 and B210M; for extruded tubes see Specifications B221 and B221M; for seamless pipe and seamless extruded tube used in pressure applications see Specification B241/B241M; and for structural pipe and tube see Specification B429/B429M.

    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 Table 1 preceded by A9, for example, A91060 for aluminum 1060, in accordance with Practice E527.

    1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.

    1.4 This specification is the inch-pound companion to Specification B234M; 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 and health practices and determine the applicability of regulatory limitations prior to use.
