Cathodic Protection

Cathodic protection is a technique used to control corrosion of metal surfaces by making the metal itself the cathode of an electrochemical cell. This is achieved by either impressing a direct current (DC) onto the structure to be protected (impressed current cathodic protection) or by using sacrificial anodes that corrode instead of the protected metal (galvanic cathodic protection). Cathodic protection is crucial for extending the lifespan of infrastructure such as pipelines, tanks, and marine structures, preventing costly damage and ensuring safety and reliability.

Various structures benefit from cathodic protection services, including:

‍

Underground Pipelines: Cathodic protection prevents corrosion of buried pipelines used in oil and gas transmission, water distribution, and sewage systems.

Aboveground Storage Tanks: Tanks storing petroleum products or chemicals are susceptible to corrosion, making them suitable candidates for cathodic protection.

Marine Structures: Piers, docks, ships, and offshore platforms are exposed to harsh marine environments and benefit from cathodic protection to prevent corrosion.

Steel Reinforced Concrete: Cathodic protection can be applied to steel reinforcement within concrete structures such as bridges, parking garages, and highway structures to prevent deterioration.

‍

Determining if a structure needs cathodic protection involves several steps:

‍

Corrosion Assessment: Conduct a thorough corrosion risk assessment of the structure based on its material, environment, and service conditions.

Inspection and Testing: Perform visual inspections and non-destructive testing techniques such as ultrasonic testing and electromagnetic inspection to detect signs of corrosion.

Consultation with Experts: Consult with cathodic protection specialists who can analyze assessment data, recommend appropriate protection systems, and develop a cathodic protection plan tailored to the structure's needs and regulatory requirements.
