Anotácia textu normy ASTM B234-17 :
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 specification2 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
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, 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. |
