The deleterious effects of metallic ions on the corrosion of ferrous alloys exposed to oxidizing acids has been investigated by this writer and other authors. Have you conducted any similar experiments?
We have conducted no experiments in oxidizing acids containing metal cations. A systematic study of this nature should be of considerable interest.
Has cathodic protection been applied to the pipes described in your paper?
Except for one river crossing we have not found it necessary to utilize cathodic protection on the pipes described in the paper. Most of our lines pass through highly congested areas which would provide us with a number of interference problems if cathodic protection were applied.
If you wanted to apply this method to another metal, would you merely measure the maximum pit depths on a series of specimens, plot the results on the extreme value probability paper, and see if a straight line is...
