- Overall, cathodic protection is a critical method for preserving the integrity and longevity of metallic structures exposed to corrosive environments, ensuring operational safety and efficiency in various industries.
- This method is widely employed to protect underground pipelines, tanks, ship hulls, offshore platforms, and other metallic structures from corrosion caused by environmental factors such as soil or water.
- Types of Cathodic Protection: Galvanic (Sacrificial) Anodes: This method uses more active metals such as zinc or magnesium, which are electrically connected to the structure to be protected.
- In cathodic protection, the metal structure is made the cathode by applying a direct current (DC) to it from an external source, typically a sacrificial anode or an impressed current system.
- How Cathodic Protection Works: Electrochemical Principle: Corrosion occurs when a metal surface acts as an anode and loses electrons, oxidizing in the presence of an electrolyte (e.
- Impressed Current Cathodic Protection: In this method, an external power source (rectifier) is used to supply a controlled DC current to the structure to be protected.
- Cathodic protection (CP) is a technique used to control the corrosion of metal surfaces by making the metal itself the cathode of an electrochemical cell.
- Reference Electrodes: Used to measure the potential of the protected structure relative to a known standard, ensuring proper CP operation.
- Applications: Pipelines: CP is extensively used to protect underground and underwater pipelines transporting oil, gas, water, etc.
