(Specification)Standard Specification for Cold-Drawn Buttweld Carbon Steel Mechanical Tubing
Standard Specification for Cold-Drawn Buttweld Carbon Steel Mechanical Tubing
ABSTRACT
This specification covers cold-drawn buttweld carbon steel tubes for use as round, square, rectangular or special shape mechanical tubing. The carbon steel can be made unless a specific type of melting process is required by the purchaser. Heat and product analysis shall be made to determine the specified percentages of chemical elements to which steel tubes shall conform to. The tubing shall be free of injurious defects and shall have a workmanlike finish. Unless otherwise specified, both outside and inside surfaces of the tubing shall be coated with a film of rust-retarding oil before shipping.
SCOPE
1.1 This specification covers cold-drawn buttweld carbon steel tubes for use as mechanical tubing.
1.2 This specification covers round, square, rectangular, and special shape mechanical tubing.
1.3 Round tube size ranges covered are outside diameters up to 3 1/2 in. (88.9 mm) and wall thickness from 0.035 to 0.500 in. (0.89 to 12.70 mm).
1.4 Optional supplementary requirements are provided and, when desired, shall be so stated in the order.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 This product is available in various grades (Section 6 Tables 1 and 2 and conditions (Section 5).
1.7 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
