An insight into cathodic protection in hazardous areas
Corrosion is a natural process where metals are gradually degraded and destroyed by chemical and electrochemical reactions with their environment. Galvanic and impressed current CP systems are used to control the corrosion of steel in structures and involve voltages and currents being introduced into the structures. Occasionally, these structures are situated in hazardous environments where there are explosive liquids and gases, creating a risk of an explosion occurring if electrical voltages and currents are not managed carefully.
