WebAug 20, 2024 · Iron return pipe systems undergo critical corrosion; thus, if the concentration of CO 2 in the boiler water is high enough, the iron carbonate will be formed, and it changes to ferrous hydroxide and CO 2 further, which is the obvious corrosive medium. WebPipes used to distribute drinking water are made of plastic, concrete, or metal (e.g., steel, galvanized steel, ductile iron, copper, or aluminum). Plastic and concrete pipes tend to be resistant to corrosion. Metal pipe corrosion is a continuous and variable process of ion release from the pipe into the water. house for sale fall river ma molotov https://automotiveconsultantsinc.com
