The following bibliographic material is provided to assist you with your purchasing decision:


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.

Scope

1.1 This specification establishes the requirements for arc-welded pipe for use in brackish water or seawater piping systems.

1.2 Units—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.

1.3 The following hazard statement pertains only to the test method described in 8.2 and 14.3.2 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.

1.4 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.

Significance and Use

16.1 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 E29.
