Corrosion Fatigue in Boiler Tubes – Thielsch Engineering

Off-line boiler corrosion is usually caused by oxygen in-leakage. Low pH causes further corrosion. Low pH can result when oxygen reacts with iron to form hydroferric acid. This corrosion product, an acidic form of iron, forms at water-air interfaces. Corrosion also occurs in …

Common types of corrosion in refinery heat exchangers - Yaang

Mar 01, 2021 · By analyzing the results in Table 2, it can be found that the content of sulfur and oxygen in the three-layer structure gradually increases from the inside to the outside, which indicates that the outer wall of the tube wall is severely corroded by sulfur in the boiler combustion state. Sulfur can penetrate into the corrosion layer and diffuse into the interior, which cause the reaction with metal substrate, and …
