CONDENSER HEN quality is of paramount im- portance in condenser tubes, en- gineers specify the cupping process. ALL Scovill Admiralty Condenser Tubes are produced by this process, which, in itself, is a safeguard of tube quality. Discs are blanked from slabs of Scovill Admiralty Metal and cupped. None but sound metal will survive this cupping opera- tion which is repeated until the cup is of a length best handled at the draw benches. Scovill Admiralty Condenser Tubes are annealed under pyrometer control after each drawing operation. The finished tubes are heat treated to obtain an exceedingly fine uniform grain structure which is so effective in the fight against corrosion. Scovill means SERVICE to all who require parts or finished products of metal. Great factories equipped with the last word in laboratories, and modern machinery manned by skilled workmen, are at your disposal. ’Phone the nearest Scovill office.
