Abstract

A SEAMLESS TUBE FOR A HEAT EXCHANGER TUBE OF A CROSS-FINNED TUBE HEAT EXCHANGER IS MADE OF PHOSPHOROUS-DEOXIDIZED COPPER. THE RATIO (t/D) OF THE THICKNESS (MM) TO THE OUTER DIAMETER (MM) OF THE SEAMLESS TUBE IS 0.040 OR LESS. THE SEAMLESS TUBE HAS A TENSILE STRENGTH (?B) OF 245 MPA OR MORE, A 0.2% PROOF STRESS (?0.2) OF 140 MPA OR LESS, AND AN ELONGATION (?) OF 40% OR MORE. THE SEAMLESS TUBE MADE OF PHOSPHOROUS-DEOXIDIZED COPPER WITH THIS STRUCTURE EXHIBITS HIGH STRENGTH AND CAN BE HAIRPIN-BENT PROPERLY.
