(Specification)Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Seamless Extruded Tube
Standard Specification for Aluminum and Aluminum-Alloy Seamless Pipe and Seamless Extruded Tube
ABSTRACT
This specification covers aluminum and aluminum-alloy seamless pipe and seamless extruded tube. The pipe and tube shall be produced from hollow extrusion ingot (cast in hollow form, or drilled, or pierced from solid ingot) and shall be extruded by use of the die and mandrel method. The material shall conform to the chemical composition requirements specified. The determination of chemical composition shall be made in accordance with suitable chemical (test methods E 34) or spectrochemical (test methods E 227, E 607, and E 1251) methods. Alloys may be solution heat-treated and quenched at the extrusion press in accordance with practice B 807 for the production of T4 and T6-type tempers, as applicable. The material shall conform to the tensile property requirements specified. The tension tests shall be made in accordance with test methods B 557. The stress-corrosion cracking test shall be performed on extruded tube. The stress-corrosion test shall be made in accordance with test method G 47. The aluminum alloy coating of clad tube shall comprise the inside surface (only) of the tube and its thickness shall be approximately 10 % of the total wall thickness of the tube.
SCOPE
1.1 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 H35.2M. Nonstandard alloys, tempers, and sizes of pipe are produced as seamless extruded tube. Note 1—Throughout this specification, use of the term alloy, in the general sense, includes aluminum as well as aluminum alloy.Note 2—For other seamless drawn tubes, see Specification B210 or Specification B483/B483M. For extruded tube see Specification B221, and for structural pipe and tube see Specification B429/B429M.
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 5preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 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.
1.4.1 The SI units are shown either in brackets or in separate tables.
