Cathodic Protection

Overview of Cathodic Protection Services for Corrosion Control

Cathodic protection is a proven method for controlling corrosion in buried and submerged infrastructure assets exposed to aggressive environments. By applying electrical current, these systems reduce the natural electrochemical reactions that cause metal deterioration. This approach provides continuous protection and is widely used to preserve the integrity of pipelines, tanks, and other critical assets.

These services incorporate design, monitoring, and performance evaluation to ensure long-term effectiveness. Understanding environmental conditions, soil resistivity, and system requirements allows for the development of cathodic protection systems that provide reliable and consistent corrosion control.

By implementing properly designed cathodic protection systems, asset owners can significantly reduce corrosion rates, extend service life, and minimize the risk of leaks or structural failures.

Cathodic Protection System Design, Testing, and Troubleshooting Capabilities

Corrosion Probe, Inc. provides cathodic protection services designed to protect infrastructure assets under real-world operating conditions. Systems are developed based on asset type, environmental exposure, and corrosion risk to ensure effective and efficient performance.

Our services include cathodic protection system design, installation support, and commissioning, as well as ongoing testing and monitoring. We perform field measurements such as potential surveys, current output verification, and interference testing to confirm system effectiveness. Troubleshooting and system adjustments are also conducted to address performance issues and optimize protection levels.

All data is documented and interpreted to provide clear insight into system performance and compliance with applicable standards. These services support both new installations and existing systems, ensuring long-term corrosion control and asset protection.

Applications of Cathodic Protection in Water, Wastewater, and Industrial Systems

Cathodic protection is applied across a wide range of infrastructure systems including buried pipelines, storage tanks, marine structures, and other metallic assets exposed to soil or water environments. These assets are highly susceptible to corrosion due to constant exposure to moisture, corrosive species, and varying environmental conditions.

These systems are commonly implemented during new construction to prevent early-stage corrosion and are also retrofitted onto existing assets to mitigate ongoing deterioration. Cathodic protection is often integrated into broader corrosion control programs and used alongside coatings and linings for comprehensive protection.

By actively controlling corrosion processes, cathodic protection improves asset reliability, reduces maintenance costs, and helps extend the service life of critical infrastructure systems.

Frequently Asked Questions

Cathodic protection is a corrosion control method that uses electrical current to reduce or prevent the deterioration of metal surfaces exposed to soil or water environments.
The two main types are galvanic (sacrificial anode) systems and impressed current systems, selected based on asset size, environment, and protection requirements.
Common assets include pipelines, storage tanks, and other buried or submerged metallic structures that are exposed to corrosive environments.
Performance is monitored through field testing such as potential measurements and system checks to ensure adequate protection levels are maintained.
Yes, cathodic protection is used alongside coatings and linings, providing secondary protection where breaches in those barrier systems expose bare metal, resulting in a more complete and effective corrosion protection system.
