| ASTM B210 Standard Specification for Aluminum and Aluminum-Alloy Drawn Seamless Tubes | |
| This specification covers aluminum and aluminum-alloy drawn seamless tubes in straight lengths and coils for general purpose. The tube shall be produced by drawing an extruded tube made from hollow extrusion ingot (cast in hollow form or pierced) and extruded by the use of the die and mandrel method. The tubes 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 607 and E 1251), methods. The tube shall conform to the tensile property requirements specified. The tension tests shall be made in accordance with test methods B 557M. Flattening test specimens shall be flattened sidewise under a gradually applied load so as to give a uniform radius of bend until the minimum outside diameter under load is not more than F times the wall thickness of the tube as specified. The specimen shall be forced axially with steady pressure over a hardened and polished tapered steel pin having a included angle, to produce a flare having the permanent expanded outside diameter specified. When specified, heat treatment of applicable tempers shall be in accordance with practice B 918. The different methods for leak testing of tubes are presented. | |
| 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 0.083 in. and only in nonheat-treatable alloys. 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 1 preceded by A9, for example, A91100 for aluminum designation 1100 in accordance with Practice E527. Note 1—See Specification B483/B483M for aluminum-alloy drawn tubes for general purpose applications; Specification B234 for aluminum-alloy drawn seamless tubes for condensers and heat exchangers; and Specification B241/B241M 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. 1.3 A complete metric companion to Specification B210 has been developedSpecification B210M; therefore, no metric equivalents are presented in this specification. 1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
