Standard Specification for Copper-Nickel Alloy Castings
ASTM B369/B369M-24
Organization:
ASTM - ASTM International
Year: 2024
Abstract: This specification establishes the requirements for threadless, seamless, and deoxidized copper pipes in straight lengths, in all nominal or standard pipe sizes, for piping systems that are assembled with brazed-joint pipe fittings. The pipe shall be produced from coppers with either UNS No. C10300 or C12200. The materials for manufacture shall be cast billets, bars, or tubes of such purity and soundness as to be suitable for processing by hot extrusion or piercing, and subsequent cold working to produce a uniform wrought structure in the finished product. Products shall be produced in the H58 (drawn general purpose) temper. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (outer and inner diameters, wall thickness, cross-sectional area, theoretical weight, mass, length, and roundness or squareness), mechanical (tensile strength and Rockwell hardness), and chemical composition requirements. Products shall also meet performance requirements under microscopical examination, electromagnetic (eddy-current) test, hydrostatic test, and pneumatic test.

| scope | 1.1 This specification covers the requirements for copper-nickel alloy castings with nominal compositions shown in Table 1. 1.2 Castings of these alloys are used primarily for corrosion-resistance applications such as construction or pressure vessels, particularly for marine pumps, valves, and fittings. 1.3 These alloys are considered weldable, but they may be ordered with a weld test to ensure weldability. When extensive welding is to be performed on the casting, weldability tests should be specified in the ordering information (5.2.6) to ensure proper welding characteristics. 1.4 Units—The values stated in either inch-pound units 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.5 The following hazard statement applies only to Section 8, Weldability Test, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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. | |
