Standard Specification for Welded Copper and Copper-Alloy Heat Exchanger Tube
|Publication Date:||1 October 2018|
|ICS Code (Copper products):||77.150.30|
This specification establishes the requirements for welded tube of copper and various copper alloys up to 31⁄8 in., inclusive, in diameter, for use in surface condensers, evaporators, heat exchangers, and general engineering applications. The following coppers or copper alloys are involved:2

A Copper UNS Nos. C10800 and C12200 are classified in Classification B224.
The values stated in either inch-pound or SI units are to be regarded separately as standard.Within the text, SI units are shown in brackets. 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.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning-Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.
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.
A Summary of Changes section appears at the end of this standard
New designation established in accordance with Practice E527. In the new UNS system, the designations for copper alloys are simply expansions of the present standard designations by a prefix "C" and a suffix "00."
