This specification covers seamless and welded titanium and titanium 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, evaporators, heat exchangers and similar heat transfer apparatus in unfinned end diameters of a specific size. Tubes shall be furnished with unenhanced ends in the annealed condition and shall be suitable for rolling-in operations. Each tube shall be subject to a nondestructive eddy current test, and either a pneumatic or hydrostatic test.
