Corrosion behavior of several metals in ethylene glycol-base heat-transfer fluids under conditions encountered in solar energy systems

Materials research activities at the National Bureau of Standards (1975-1982) pertaining to active solar heating and cooling systems

“…In another laboratory-based study [27], Argonne National Laboratory evaluated the corrosion behavior of representative metals (6061 aluminum, CA 122 copper, black iron, 1008 low-carbon steel, galvanized black iron and galvanized 1008 steel) in ethylene glycol-water solutions under temperature and flow conditions common to solar collector systems. The corrosion experiments were conducted under the heat-flux conditions encountered in normal operations.…”

Corrosivity of propylene glycol solution in solar-energy fluid systems

“…The FLS is sensitive to temperature fluctuation, and its voltage reading decreases with increasing temperature. 2 Since inhibited glycol solutions are stable and not susceptible to degradation at room temperature, 100°F (38 °C) was arbitrarily chos_en as the minimum •temperature (Tmin) to use in finding the monthly average voltage at each site. The results are summarized in Table 2.…”
