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.

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.

Significance and Use

For purposes of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E 29 :

1. Scope

1.1 This specification establishes the requirements for annealed copper-alloy strip for the manufacture of flexible metal hose produced from Copper Alloy UNS Nos. C41100 and C50500.

1.1.1 The nominal compositions are as follows:

1.2 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 precautionary statement pertains only to the test method portion, Section 13, of this specification: 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
