C70600...90-10 copper-nickel
C70620...90-10 copper-nickel (Modified
for Welding)
C71000...80-20 copper-nickel
C71500...70-30 copper-nickel
C71520...70–30 copper-nickel (Modified
for Welding)
C71640...copper-nickel-iron-manganese
C72200......
____________

A Copper UNS Nos. C10800 and C12200 are classified in Classification B224.

1.2 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.

1.3 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.

WarningMercury 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 mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA’s website (http://www.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law. (Mercury is a definite health hazard in use and disposal. (See 12.1.1.))

Standard Specification for Welded Copper and Copper-Alloy Heat Exchanger Tube

This specification covers welded tube of specific copper and various copper alloys of a limited range of diameters, for use in surface condensers, evaporators, heat exchangers, and general engineering applications. The product shall be manufactured by forming the material into a tubular shape on a suitable forming mill. Welding of tube shall be accomplished by forge-welding, fusion-welding, or full finishing that produces a forge weld leaving no crevice in the weld seam visible to the unaided eye. The tube shall conform to tensile strength and yield strength requirements, and shall be subject to expansion, flattening, and reverse bend tests. Mercurous nitrate or ammonia vapor tests shall be required only for selected UNS Numbers of Copper Alloys. Each tube shall be subjected to eddy-current, hydrostatic, and pneumatic tests.
