This specification covers arc-welded copper-alloy pipe for use in brackish water or seawater piping systems. The pipe shall be made from annealed copper alloy sheet or plate that conforms to the requirements specified for copper alloys with UNS nos. C61300, C61400 C70620 and C71520. These specifications reference test methods E 62, E 76, and E 478 for the appropriate chemical analysis. Welded joints shall be made either manually or automatically by an arc-welding process. The pipe material shall conform to the chemical composition requirements prescribed. With test taken across any weld, the pipe shall be capable of conforming to the required transverse tensional strength value. The transverse-face and root-guided bend test shall be taken with the weld in the center of the test specimen and there shall be no open defects exceeding the required value measured in any direction on the convex surface of the specimen when tested in accordance with test methods E 190. Each length of pipe shall be capable of withstanding an internal hydrostatic pressure without showing evidence of weakness, defects, or leakage. All welded joints in any individual length of pipe shall be radiographed completely. Weld thickness shall conform to wall-thickness requirements after removal of reinforcement.
