Standard Specification for Welded Copper-Nickel Pipe
The following bibliographic material is provided to assist you with your purchasing decision:
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
1.1 This specification establishes the requirements for welded copper-nickel alloy pipe for general engineering purposes. The following alloys are covered:
| Copper Alloy UNS No. | Type of Metal |
| C70600 | 90-10 copper-nickel |
| C70620 | 90-10 copper-nickel |
| (Modified for Welding) | |
| C71500 | 70-30 copper-nickel |
| C71520 | 70-30 copper-nickel |
| (Modified for Welding) |
1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems could result in nonconformance with the specification.
Significance and Use
For purposes of determining compliance with the specified limits for requirements of the properties listed in the following table, and observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.
| Property | Rounded Unit for Observed or Calculated Value |
| Chemical composition | nearest unit in the last right-hand place of figures of the specified limit |
| Tensile strength Yield strength | nearest ksi [nearest MPa up to 10 ksi, incl, nearest 5 MPa over 10 ksi] |
| Elongation | nearest 1 % |
