Standard Specification for Seamless Copper Alloy (UNS No. C69100) Pipe and Tube

Abstract

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.
