This specification establishes the requirements for standard sized seamless pipes, both regular and extra strong, and seamless tubes in straight lengths produced from copper alloy UNS No. C69100 for general engineering purposes. The materials for manufacture shall be cast or extruded shells of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in tempers TB00 (soft-annealed), TF00 (precipitation-hardened), and HR50 (drawn stress relieved). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, wall thickness, inside and outside diameters, cross-sectional area, nominal weight, length, squareness of cut, and density), mechanical (tensile and yield strengths, Rockwell hardness, and elongation), physical (electrical resistivity and coefficient of thermal expansion), and chemical composition requirements. Products shall also undergo nondestructive eddy-current and hydrostatic tests.
1.1 This specification covers the requirements for copper alloy UNS No. C69100 seamless pipe in standard pipe sizes, both regular and extra strong, and seamless tube in straight lengths for general engineering purposes.
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 safety hazard caveat pertains only to the test method portion, Section described in 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.
