Cathodic protection (CP) is a critical service in the oil and gas industry, ensuring the longevity and safety of pipelines, storage tanks, and other critical infrastructure by preventing corrosion. It uses an electrochemical process to mitigate corrosion on metallic structures by introducing a sacrificial metal (anode) that corrodes instead of the protected structure. This process extends the lifespan of valuable assets and helps prevent potential failures, ensuring safe and reliable operations.
How Cathodic Protection Works in Oil and Gas:
Sacrificial Anode And Impressed Current:
In this method, a more reactive metal (the anode) is connected to the structure being protected. The anode corrodes, sacrificing itself to protect the structure from corrosion. This method uses an external power source to deliver a current to the structure, forcing it to become a cathode and preventing corrosion.
