Besides providing the necessary heat, steam also serves other purposes, including cleaning, moisturizing, and separation (stripping). All these benefits notwithstanding, steam is conducive to corrosion – often occurring in non-accessible places (e.g., corrosion under insulation, CUI) –, which has an enormous impact on plant integrity, safety, and operation costs.
To suppress corrosion, a chemical water treatment program is necessary to control and adjust the pH value and monitor the concentrations of corrosive ions, corrosion inhibitors, and corrosion by-products.
Metrohm offers a range of instruments and methods for measuring corrosion parameters. Read more about parameters that are relevant in the context of corrosion below.
