2、the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers seamless pipe and seamlesse
3、xtruded 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 inapplications involving internal pressure.NOTE1Throughout this specification use of the term alloy in thegeneral sense includes aluminu
4、m as well as aluminum alloy.NOTE2For drawn seamless tubes,see Specifications B210 andB210M;for extruded tubes,Specifications B221 and B221M;for drawnseamless tubes for condensers and heat exchangers,Specifications B234and B234M;for seamless pipe and seamless extruded tube,B241/B241M;for round welded
5、 tubes,Specification B313/B313M;for seamless con-denser 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.1.2 Alloy and temper designations a
6、re in accordance withANSI H35.1 H35.1M.The equivalent Unified NumberingSystem alloy designations are those of Table 3 preceded byA9,for example,A93003 for aluminum alloy 3003 in accordancewith Practice E527.1.3 For acceptance criteria for inclusion of new aluminumand aluminum alloys in this specific
7、ation,see Annex A2.1.4 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The values stated in eachsystem are not exact equivalents;therefore,each system shallbe used independently of the other.Combining
