\n Abstract <\/b><\/p>\n

This specification establishes the requirements for welded copper tube with a longitudinal seam free of filler metal produced from sheet or strip of one of the Copper UNS Nos. C10100, C10200, C10300, C10800, C11000, C12000, C12200, and C14200. Copper C11000 welded tube shall not be used in applications where hydrogen embrittlement during heating is a concern. Tempers of the welded tube types are as follows: as-welded: WM50, WM02, or WM04, welded and annealed: W060 and W050, welded and cold drawn: WH00, WH02, and WH04, and fully finished: O60, O50, H55, H58, and H80. The product shall be manufactured by forming the material into a tubular shape on a suitable forming mill and welding shall be accomplished by any process that produces forge or fusion welds. The external flash of forge welded tube shall be removed by scarfing and the internal flash shall be treated by IFI (to remain in the as-welded condition), IFR (scarfing) or IFD (rolling or drawing) technique. The material shall conform to the chemical composition requirements prescribed for copper, phosphorus, and arsenic, as determined by chemical analysis. The welded tubes shall meet the requirements specified for grain size, electrical mass resistivity, mechanical properties such as tensile strength and Rockwell hardness, dimensions, and mass. Performance requirements includes microscopical examination, hydrogen embrittlement susceptibility test, and expansion test. Requirements for tensile, electromagnetic (eddy-current), hydrostatic, and pneumatic tests are detailed.<\/p>\n

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. <\/i> <\/font><\/p>\n

Significance and Use <\/b><\/p>\n

For purposes of determining compliance with the specified limits for requirements of the properties listed in the following table and for dimensional tolerances, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29<\/span> :<\/p>\n

1. Scope <\/b><\/p>\n

1.1 This specification establishes the requirements for welded copper tube with a longitudinal seam free of filler metal produced from sheet or strip of the following coppers:<\/p>\n

1.2 Unless otherwise specified in the contract or purchase order, product furnished of any listed copper, with the exception of copper C11000, shall be considered acceptable.<\/p>\n

1.2.1 Copper C11000 welded tube shall not be used in applications where hydrogen embrittlement during heating is a concern.<\/p>\n

1.3 Units <\/span> \u2014 <\/span> Values stated in inch-pound units are to be regarded as standard except for grain size, which is given in SI units. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.<\/p>\n

1.4 The following hazard caveat pertains only to Section 13 of this specification: <\/span> 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. <\/span><\/p>\n
