Which outcome results on a corroding pipeline when cathodic protection fails?

💡 Explanation

When cathodic protection stops, reduction of oxygen at the cathode sites becomes limited because the electron supply ceases; therefore the oxidation (corrosion) at anode sites accelerates, rather than hydrogen embrittlement being mitigated due to lessened hydrogen production.
