This specification covers the requirements for seamless UNS C70400, C70600, C71000, C71500, C71520, and C72200 copper-nickel pipes and tubes in straight lengths suitable for engineering applications. UNS C70620 and C71520 copper alloys are intended for products that are to be welded subsequently. Each product should be manufactured from cast billets by hot extrusion or piercing and then subjected to cold working and annealing. The standard tempers for the products in this specification are soft annealed (O60), light drawn (H55), hard drawn (H80), and hard drawn and end annealed (HE80). Pipe and tube tensile properties, Rockwell hardness, and test performance should conform to the values specified herein. Performance requirements include those from expansion, flattening, and eddy Current tests.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification establishes the requirements for seamless copper-nickel pipe and tube in straight lengths, suitable for general engineering purposes. The alloys involved are copper alloys UNS Nos. C70400, C70600, C70620, C71000, C71500, C71520, and C72200.
1.1.1 Copper alloys UNS Nos. C70620 and C71520 are intended for product that will be subsequently welded.
1.2 Units—Values stated in 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 nonconformance with the specification.
1.3 The following safety hazard caveat pertains only to the test methods described in the Test Methods section of 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 and health practices and determine the applicability of regulatory limitations prior to use.
