Cathodic Protection

Cathodic Protection

Cathodic Protection is one of the most effective methods for preventing most types of corrosion on underground metal surfaces, such as oil and gas pipelines, using an electrochemical means of corrosion control.
There are two types of cathodic protection: galvanic anode and impressed current cathodic protection. Both provide a cathodic protection current flow from cathodic protection anodes placed within the same electrolyte as the metal to be protected. The current flows from the anode into the electrolyte. It discharges onto the metal, controlling the corrosion. It must flow within the metallic circuit (the metal plus the cables) and back to the anode to complete the circuit.
Shiraz Mechanic Industrial Group designs and implements both methods of cathodic protection for various plants and systems.
