| Abstract: | Corrosion damage in an industrial cooling system In several industrial cooling systems after relatively short operation time comparable corrosion occurred. The reason for this damage was the combined installation of galvanized steel pipes and heat exchangers made of copper, well-known as the reason for the corrosion damage in house installations. The galvanized surfaces of the condenser tubes in the relevant cooling-water circulation showed copper-induced pitting corrosion and break-throughs in the pipewalls. As the result, the cooling fluid ammonia entered into the water circulation which led to dissolving of nearly all of the zinc coating. |
