Direct Conclusion
Under-deposit corrosion occurs in oxygen-depleted and ion-concentration gradient environments, leading to localized electrochemical attack that is often more hazardous than uniform corrosion.
Judgment Criteria
- 01
The denser the scale layer, the higher the risk of localized corrosion.
- 02
Regular inspection and descaling reduce the risk of perforation.
Responsibility and Timeliness
