Engineering practice proves that in actual seawater environments, the outer coating can provide effective corrosion protection. What is AC corrosion?What is AC corrosion?AC electrical corrosion is caused by induction, usually when pipelines run parallel to high-voltage electrical lines (see Figure 3). The pipe intercepts the AC current, which then travels along the pipe. Eventually the current returns to its source through the soil, completing the circuit.Combatting corrosion in piping installations What is cathodic protection corrosion?What is cathodic protection corrosion?The Basics of Cathodic Protection Corrosion is a naturally destructive phenomenon that occurs when some metals are exposed to the environment. The reaction between air, moisture and the metal substrate gives rise to specific chemical reactions that cause the metal to convert to its more chemically-stable oxide, hydroxide or sulfide form.Corrosionpedia - The Basics of Cathodic Protection

Why do pipelines have sacrificial anodes?Why do pipelines have sacrificial anodes?This is why steel pipelines should have sacrificial anodes electrically attached to them when they are placed into the ground, completing electrical circuits. The anodes give up energy to protect the steel and the steel will not corrode, but the anode will corrode and will have to be replaced when its energy is depleted.Combatting corrosion in piping installations(PDF) Analysis of internal corrosion in subsea oil pipeline

Bimetallic corrosion, as its name implies, is a unique type of corrosion that occurs between the pairing of two metals. This corrosion is observed in several situations where dissimilar metals are in direct or indirect contact with each other. Bimetallic corrosion is usually characterized by accelerated corrosion in one metal while the other remains unaffected.
