Standard Specification for Aluminum and Aluminum-Alloy Drawn Seamless Tubes (Metric)
|Publication Date:||15 May 1995|
|ICS Code (Aluminium products):||77.150.10|
1. Scope *
1.1 This specification covers aluminum and aluminum-alloy drawn seamless tubes in straight lengths and coils for general purpose and pressure applications in alloys (Note 2), tempers, and thicknesses shown in Table 2. Coiled tubes are generally available only as round tubes with a wall thickness not exceeding 2.00 mm and only in nonheat-treatable alloys.
1.2 Alloy and temper designations are in accordance with ANSI H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by, for example, A91100 for aluminum 1100 in accordance with Practice E 527.
1.3 Preferred metric sizes are in accordance with ANSI B32.5.
NOTE 1--See Specification B 483M for aluminum and aluminum-alloy drawn tubes for general purpose applications, Specification B 234M for aluminum-alloy drawn seamless tubes for condensers and heat exchangers, and Specification B 241/B 241M for aluminum-alloy seamless pipe and seamless extruded tube.
NOTE 2--Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
1.4 This specification is the metric counterpart of Specification B 210.
1.5 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
