B359 C44300 C44500 Copper Alloy Low Fin Tube U Bend for Heat Exchangers
B359 describes seamless copper and copper alloy tubing on which the
external or internal surface, or both, has been modified by a
cold-forming process to produce an integral enhanced surface for
improved heat transfer. The tubes are used in surface condensers,
evapora-
tors, and heat exchangers and are normally made from the following
copper or copper alloys:
