Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Seamless Extruded Tube
|Publication Date:||1 February 2016|
|ICS Code (Aluminium products):||77.150.10|
This specification2 covers aluminum and aluminum-alloy seamless pipe in the alloys (Note 1) and tempers shown in Table 1 [Table 2] and seamless extruded round tube in the alloys and tempers shown in Table 3 [Table 4] intended for pressure applications. The standard sizes for seamless pipe are listed in Table 16.7 of ANSI H35.2 and H35.2(M). Nonstandard alloys, tempers, and sizes of pipe are produced as seamless extruded tube. Also included in this standard are seamless extruded pipe and seamless extruded tube for Oil & Gas Transmission previously covered under Specification B345/B345M.
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 condenser and heat exchanger tubes with integral fins, Specification B429/B429M; and for drawn tube for general purpose applications, Specifications B483/B483M.
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 5 preceded by A9, for example, A91100 for aluminum 1100 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 SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
The SI units are shown either in brackets or in separate tables.
