Standard Specification for Welded Copper and Copper-Alloy Heat Exchanger Tube
|Publication Date:||1 April 2012|
This specification established 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
The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 and health practices and determine the applicability of regulatory limitations prior to use.
Warning-Mercury has been designated by EPA and
many state agencies as a hazardous material that can cause central
nervous system, kidney, and liver damage. Mercury, or its vapor,
may be hazardous to health and corrosive to materials. Caution
should be taken when handling mercury and mercurycontaining
products. See the applicable product Material Safety Data Sheet
(MSDS) for details and EPA's website
