Improvements relating to the prevention of electrolytic corrosion in surface condensers and like heat-exchange apparatus
Реферат: 185,436. Wurstemberger, F. von. March 8, 1921. Corrosion, preventing.-In a surface condenser or like apparatus having tubes 31, Fig. 3, and a tube-supporting plate 33 made of copper or copper alloy, means are provided to prevent the generation of galvanic currents between the iron stays or like strengthening parts and the tube-supporting plate, thus preventing corrosion. The tube-plates 32 are stayed by transverse stays 34. Longitudinal stays having coverings of copper or copper alloy at the parts passing through the supporting plate may be used. The iron stay rods 61, Fig. 5, pass through the supporting plate 63 without touching it, the holes being tapered to prevent accumulation of salt deposit and rust between the stay and the plate.
