Reasons for corrosion

2018-11-15View Original

Thread Content

These are pictures of the acid return pipeline before it was replaced during our maintenance work. How many possible causes could there be for the corrosion?

Is the acid concentration meter in the drying tower working properly? Is the drying tower also equipped with a butterfly-shaped bottom?

The acid concentration is too low; 70% acid can corrode white steel to the point of complete destruction
