Annotation of standard text ASTM B241/B241M-22 :

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.

Additional information

1. Scope

1.1?This specificationNote 1:?Throughout this specification, use of the term Note 2:?For drawn seamless tubes, see Specification B210/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, Specification B483/B483M.

1.2 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 4 preceded 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.

1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
