Cathodic Protection (CP) & Pipeline Integrity Products: Technical Guide
Cathodic Protection (CP) systems protect buried and submerged steel pipelines from corrosion by maintaining proper electrical potentials. These systems extend asset life, reduce maintenance costs, and ensure compliance with PHMSA, NACE, and utility regulations. CP is essential for gas utilities, oil transmission, water authorities, and industrial facilities that depend on long-term pipeline integrity.
What Is Cathodic Protection and How Does It Work?
Cathodic Protection prevents corrosion by shifting the pipeline’s electrochemical potential in a more protective (negative) direction. This is achieved through two core methods:
1. Galvanic (Sacrificial) CP Systems
- Uses magnesium, zinc, or aluminum anodes
- Anodes corrode instead of the steel pipeline
- Ideal for short pipelines, isolated services, and low-resistivity soils
- No external power source needed
2. Impressed Current CP (ICCP) Systems
- Powered systems using rectifiers and high-performance anodes (e.g., MMO)
- Adjustable current output for long pipelines
- Suitable for high-resistivity soils or high current demands
- Best for large networks and transmission lines
Core Components of CP Systems
Cathodic Protection requires engineered components working together to deliver stable, measurable corrosion prevention.
Anodes
- Magnesium: High driving potential; excellent for high-resistivity soil
- Zinc: Stable potential; ideal for marine or low-resistivity conditions
- MMO/ICCP: Long service life and high output for large pipelines
Test Stations
- Enable monitoring of structure-to-soil potential
- Multi-terminal setups support multiple circuits
Reference Electrodes (Cu/CuSO₄)
- High-accuracy measurements (±10 mV)
- Used for compliance testing and pipeline surveys
Bonding & Connections
- Cadweld connections, test leads, insulating joints
- Maintain required continuity or isolation
Rectifiers (ICCP)
- AC-to-DC conversion
- Adjustable output for precise current control
Technical Performance Overview
Where Cathodic Protection Is Used
CP is essential across multiple utility and industrial environments.
Gas Distribution & Transmission
- Reduces corrosion on steel mains and services
- Supports 49 CFR Part 192 compliance
- Extends pipeline service life
Water & Wastewater Utilities
- Protects ductile iron pipe and steel mains from aggressive soils
- Ideal for chlorides, sulfates, and corrosive groundwater
Oil & Petrochemical Systems
- Safeguards high-value pipelines and tanks
- Integrates with SCADA and monitoring networks
Municipal & Industrial Infrastructure
- Used on buried vessels, cooling lines, and structural steel
Engineering Factors to Consider
Choosing the correct CP solution requires understanding the following:
Soil Resistivity
- <1,000 ohm-cm: Zinc or magnesium
- 5,000 ohm-cm: High-potential magnesium or ICCP
Coating Condition
- Good coatings = lower current demand
- Poor coatings = higher anode consumption or ICCP
Pipeline Length
- Long, coated lines → ICCP
- Short, isolated segments → Galvanic systems
Monitoring Requirements
- Test stations are placed at valves, road crossings, and coating transitions
- Reference cells for accurate potential readings
