Experiments were conducted to determine the effect of sustained temperature gradients of
20 C on copper pipe corrosion during stagnant conditions. An apparatus was constructed to:
apply temperature gradients to the pipes; monitor copper release to the water; and, measure
corrosion accelerating currents between the warm and cold sections of pipe. The orientation of
the pipe in relation to the temperature gradients determined whether convection currents
developed that promoted mixing during stagnation, and this influenced the magnitude of the
temperature gradient in the pipe. The temperature gradient led to significant sustained
thermogalvaniccurrents. Mixing of the water within the pipe also influenced copper leaching
and scale buildup. Includes 7 references, figures.
