Why is demineralized water corrosive?Why is demineralized water corrosive?An acidic pH (below 7) can cause acid corrosion. Demineralization removes mineral ions (i.e. solids) from water, but is incapable of removing gasses. And as soon as water is free of gasses, it is hungry for gasses.Demineralized water and corrosivity"316SS and Deionized Water Corrosion" - The Hendrix Group

316SS is commonly used to handle and store deionized water. 316SS and alloy 800 should not be corroding to the extent that you suggest. Deionized water can be corrosive to carbon steel due to its low hardness content. Harder waters, (based on calicum carbonate) can be protective due to the protective scale they deposit on the steel surface.Author Ali A. Quraishi, Muhammad S. AlAmryPublish Year 1992Why Is Dimineralized Water Corrosive? - Industrial Effect of demineralized water on carbon steel and Jul 28, 2012Dimineralized Water is NOT corrosive. Let's agree on that fact. However, contaminated DM water IS corrosive - especially if contaminated with dissolved oxygen or carbon dioxide. If oxygen is present, you get one form of corrosion rust (or iron oxidation). If carbon dioxide is present, you get acidic attack on the steel with resulting acid etching of the steel.

Deionized - Demineralized Water - Lenntech

Pure water by definition is slightly acidic and distilled water will test out around pH 5.8. The reason is that distilled water dissolves carbon dioxide from the air. It dissolves carbon dioxide until it is in dynamic equilibrium with the atmosphere. That means that the amount being dissolved balances the amount coming out of solution.Demineralised Water and Steel - ReAgent ChemicalsDemineralised water will only corrode steel if it has been contaminated with dissolved gases like oxygen or carbon dioxide. It is very important, then, to always ensure that purified water is protected from atmospheric contact.Demineralized Water Corrosion on Carbon Steel - Corrosion Effect of demineralized water on carbon steel and Jan 24, 2008If you deaerate the water to remove the oxygen, the demineralized water will not be severely corrosive for carbon steel service.

When aerated water is introduced at startup, corrosion of components takes place, thereby harming the boiler system. Many demineralized water storage tanks are dosed with ammonia and hydrazine to reduce the oxygen content.Q & A Is de-ionized water corrosive? Department of Effect of demineralized water on carbon steel and I'm puzzled as to why DI water would be noticeably more corrosive than tap water. It does become slightly acidic due to dissolved CO 2 from the air, but it's a little surprising for that to have such a big effect. The chemical potential of iron ions will of course be lower if they are at lower concentration, so DI is "hungrier" for them, just Effect of demineralized water on carbon steel and
