Standard Specification for Seamless Copper Heat Exchanger Tubes With Internal Enhancement
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers seamless, internally enhanced copper tube, in straight lengths or coils, suitable for use in refrigeration and air-conditioning products or other heat exchangers. The material of manufacture shall be cast billet, bar, tube, or so forth of copper UNS No. C12200 and shall be of such purity and soundness as to be suitable for processing into the tubular product described. The tube shall be manufactured by such hot- and cold-working processes needed to produce a homogenous, uniform wrought structure in the finished product. The material shall conform to the chemical composition requirements specified. The grain size shall be determined in the wall beneath the ridges. The microstructure shall show complete recrystallization and shall have an average grain size within the limits specified. As-fabricated and O (annealed) temper tube shall conform to the mechanical properties specified. The specimens of annealed product shall withstand the specified expansion tested as specified. Each tube shall be subjected to an eddy-current test. Tubes shall be tested normally in the fabricated temper; however, they may be tested in the annealed temper at the option of the manufacturer.
