ASTM B345/B345M-02 PDF

1.1 This specification covers seamless pipe and seamless extruded tube in the aluminum and aluminum alloys (Note 1) and tempers listed in Table 1 and Table 2, respectively. Seamless pipe and seamless tube are intended for use in applications involving internal pressure.

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

Note 2 - For drawn seamless tubes, see Specifications B 210 and B 210M; for extruded tubes, Specifications B 221 and B 221M; for drawn seamless tubes for condensers and heat exchangers, Specifications B 234 and B 234M; for seamless pipe and seamless extruded tube, B241/B 241M; for round welded tubes, Specification B 313/B 313M; for seamless condenser and heat exchanger tubes with integral fins, Specifications B 404 and B 404M; for extruded structural pipe and tube, Specification B 429; and for drawn tube for general purpose applications, Specifications B 483 and B 483M.

1.2 Alloy and temper designations are in accordance with ANSI H35.1 [H35.1M]. The equivalent Unified Numbering System alloy designations are those of Table 3 preceded by A9, for example, A93003 for aluminum alloy 3003 in accordance with Practice E 527.

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

1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
