Abstract

This specification covers welded copper-nickel alloy pipes produced from Copper Alloy UNS Nos. C70600 and C71500 for general engineering applications. Pipes may be produced in any one of the following tempers: as-welded from annealed sheets, strips, or plates (WM50); as-welded from cold-worked sheets, strips, or plates (WM00, WM01, WM02, and so forth); welded and annealed (WO50); welded, light cold drawn (WR00) or hard cold drawn (WR04), and stress relieved; or fully finished as annealed, light drawn (WH00) or hard drawn (WH04), and stress relieved. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (outside diameter, specific and stock lengths, wall thickness, squareness of cut, and roundness), mechanical (tensile and yield strengths, and elongation), and chemical composition requirements. Specimens shall also undergo nondestructive tests such as radiographic examination, eddy-current test, and hydrostatic test.

Scope

1.2 Units—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. Grain size is given in SI units.

1.3 The following safety hazard caveat pertains only to the test methods portion, Section 14, described in this specification:

1.3.1 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.

1.4 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.
