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 and pressure applications. 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. Tensile properties of the tubes such as tensile strength, yield strength, and elongation shall be determined. The specimens shall be subjected to mechanical tests such as flattening test, flare test, and bend test. The tempers shall be subjected to heat treatment and the tubes shall be tested for leaks by pneumatic and eddy-current methods.
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 0), tempers, and thicknesses shown in . 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. The equivalent Unified Numbering System alloy designations are those of preceded by A9, for example, A91100 for aluminum designation 1100 in accordance with Practice E 527. Note 2See Specification B 483 for aluminum-alloy drawn tubes for general purpose applications; Specification B 234 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.
Throughout this specification, use of the term alloyin the general sense includes aluminum as well as aluminum alloy.
1.3 A complete metric companion to Specification B 210 has been developed-Specification B 210M; 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 .
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.
