INVÄNDIG KORROSION AV KOPPARLEDNINGAR FÖR DRICKSVATTENDISTRIBUTION / Internal Corrosion of Copper Pipes for Drinking-Water Supply
Copper is a common material in building plumbing system. Copper pipes corrode in different ways wich have consequences for the useful life of the pipe and also for water quality. From a water quality point of view, the uniform corrosion is of imponance. This type of corrosion, resulting in high copper content, is common at low pH or in hard waters. In order to investigate copper corrosion mechanisms, a project is being financed by Swedish Water and Waste Water Works Association (VA-forsk) and water treatment plants. The investigations have been carried out in different scales from laboratory to fullscale distriburion systems. Tests results clearly show that the concentration of free carbon dioxide is very important for copper corrosioa. There is a positive, logarithmic correlation between carbon dioxide and copper concentration. “Complete abstract not presented.”
