Use of Aluminum for Portable Sea Water Distillation Equipment

Tests of 2000 hours duration were made to determine the suitability of aluminum as a cupro-nickel substitute in the fabrication of military sea water distillation equipment. It was found that with careful design and the elimination of copper alloys from the system, aluminum heat exchangers showed satisfactory corrosion resistance under tests conditions. Data reported include sources of copper contamination in system, alkalinity of sea water at Wrightsville Beach and Dayton Beach test areas, plus analyses (chlorides, copppr, aluminum) of sea water, compressed steam, distilled water and blowdown. 7.6.8, 6.4.2, 4.6.11
