Accelerating the aging of copper pipe

摘要

Experiments were conducted to investigate whether chemical treatments can reduce copper release from new pipes. Lime, caustic, sodium bicarbonate, and chlorine treatments decreased copper corrosion by-product release at greater than 95 % confidence, whether the treatment was applied to a new pipe or a pipe that was previously exposed to water for one week. Pre-treatments did not provide long term resistance to continuous sulfide attack.
