A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1.

3、Scope*1.1 This specification2covers aluminum and aluminumal-loy seamless pipe in the alloys (Note 1) and tempers shown inTable 1 Table 2 and seamless extruded round tube in thealloys and tempers shown in Table 3 Table 4 intended forpressure applications. The standard sizes for seamless pipe areliste

4、d in Table 16.7 of ANSI H35.2 and H35.2(M). Nonstan-dard alloys, tempers, and sizes of pipe are produced asseamless extruded tube. Also included in this standard areseamless extruded pipe and seamless extruded tube for Oil for extruded tubes, Specifications B221 and B221M; for drawnseamless tubes fo

5、r condensers and heat exchangers, Specifications B234and B234M; for seamless condenser and heat exchanger tubes withintegral fins, Specification B429/B429M; and for drawn tube for generalpurpose applications, Specifications B483/B483M.1.2 Alloy and temper designations are in accordance withANSI H35.
