ASTM B345/B345M 2011 Edition, August 1, 2011
Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Seamless Extruded Tube for Gas and Oil Transmission and Distribution Piping Systems
Includes all amendments and changes through Reinstatement Notice , August 1, 2011
Published By:ASTM International (ASTM)
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 alloy in the general sense includes aluminum as well as aluminum alloy.
NOTE 2—For drawn seamless tubes, see Specifications B210 and B210M; for extruded tubes, Specifications B221 and B221M; for drawn seamless tubes for condensers and heat exchangers, Specifications B234 and B234M; for seamless pipe and seamless extruded tube, B241/B241M; for round welded tubes, Specification B313/B313M; for seamless condenser and heat exchanger tubes with integral fins, Specification B404/ B404M; for extruded structural pipe and tube, Specification B429/ B429M; and for drawn tube for general purpose applications, Specification B483/B483M.
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 E527.
For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
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.
