Unformatted text preview: Designation: A 179/A179M 90a (Reapproved 1996) e 1 An American National Standard Used in USNRC-RDT Standards Standard Specification for Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes 1 This standard is issued under the fixed designation A 179/A179M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon ( e ) indicates an editorial change since the last revision or reapproval. e 1 N OTE Keywords were added editorially in September 1996. 1. Scope 1.1 This specification 2 covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. 1.2 This specification covers tubes 1 / 8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter. N OTE 1Tubing smaller in outside diameter and having a thinner wall than indicated in this specification is available. Mechanical property requirements do not apply to tubing smaller than 1 / 8 in. [3.2 mm] in outside diameter or with a wall thickness under 0.015 in. [0.4 mm]. 1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specifi- cation. The inch-pound units shall apply unless the M designation of this specification is specified in the order. 2. Referenced Documents 2.1 ASTM Standards: A 450/A450M Specification for General Requirements for Carbon, Ferritic Alloy, and Austenitic Alloy Steel Tubes 3 3. Ordering Information 3.1 Orders for material under this specification should include the following, as required, to describe the desired...
