Cathodic Protection Materials

Cathodic protection is one of the most effective ways to control corrosion on buried and submerged metal, from pipelines and storage tanks to well casings, marine structures, and underground steel. By making the protected structure the cathode of an electrochemical cell, cathodic protection stops the corrosion that would otherwise eat through metal over time. Doing it right takes the correct materials: anodes to supply the protective current, reference electrodes and test equipment to measure it, and the cable, connections, and accessories that tie a system together.

Where Advance Electrical Cathodic Protection Is Used

Cathodic protection is used anywhere metal is buried, submerged, or otherwise exposed to a corrosive environment and cannot easily be replaced. The materials Advance supplies go into systems across industries such as:

  • Oil and gas pipelines: Buried and above-ground pipelines protected against soil-side and atmospheric corrosion along their length.
  • Storage tanks: Aboveground and underground storage tank bottoms, where soil-side corrosion is a constant threat.
  • Water and wastewater: Buried water mains, treatment infrastructure, and steel structures in municipal systems.
  • Marine and offshore: Docks, pilings, ballast tanks, and offshore structures exposed to seawater, one of the most corrosive environments there is.
  • Utilities and infrastructure: Well casings, grounding systems, and buried steel across utility and industrial sites.


In each of these settings, the same fundamentals apply: anodes deliver the protective current, reference electrodes and meters confirm the structure is protected, and quality connections and cable keep the system reliable for years. Sourcing those materials from one experienced distributor keeps a CP project moving.

Cathodic Protection FAQs

What is cathodic protection?

Cathodic protection is a technique for controlling the corrosion of a metal surface by making it the cathode of an electrochemical cell. It is applied to buried and submerged structures such as pipelines, storage tanks, well casings, and marine structures. There are two main types: galvanic (or sacrificial anode) systems, which use a more reactive metal that corrodes in place of the structure, and impressed current systems, which use an external power source to drive protective current through anodes.

A galvanic system uses sacrificial anodes, such as magnesium, made of a metal more reactive than the structure, so the anode corrodes instead of the protected metal. It needs no external power and suits smaller or lower-current applications. An impressed current system uses a rectifier or other power source to push current through anodes, delivering much higher output for large structures or high-resistance environments. The choice depends on the size, the soil or water conditions, and the current the structure requires.

Corrosion is an electrochemical process in which metal gives up electrons and slowly dissolves. Cathodic protection stops that process by forcing the protected structure to act as the cathode of an electrochemical cell, so it receives current instead of losing it. In a galvanic system, a more reactive sacrificial anode corrodes and supplies that current on its own; in an impressed current system, a rectifier drives the current through durable anodes. Either way, the structure is kept negatively charged relative to its environment, which is the condition under which it does not corrode.
It depends on the system type and the environment. Galvanic (sacrificial anode) systems commonly last around 10 to 25 years before the anodes are consumed and need replacement, with the exact life driven by anode size and soil or water conditions. Impressed current systems are built for the long haul, with anodes often rated for 20 to 40 years or more, though power components such as the rectifier may need attention sooner. Regular monitoring and maintenance are what keep either system performing to its full design life.
Corrosion is one of the leading causes of premature failure in buried and submerged metal, and a failed pipeline, tank, or structure can mean costly repairs, environmental damage, safety hazards, and regulatory problems. Cathodic protection slows or stops that corrosion, extending the service life of critical assets and reducing the total cost of owning them. For many buried and offshore steel structures, it is also a regulatory expectation, not just a good practice.
For metallic pipelines and tanks in corrosive environments, it usually is. Cathodic protection is a widely required corrosion control measure for buried and submerged steel, particularly where long service life and regulatory compliance matter, and it is often paired with a protective coating so the two work together. Non-metallic systems such as HDPE do not need it, though metallic components connected to them frequently do. The specific requirement depends on the structure, the environment, and the governing standards for the project.
Yes, and the two are usually used together. A good protective coating limits how much metal is exposed to the environment, which reduces the current a cathodic protection system has to supply, and the cathodic protection then guards the small defects and holidays that no coating avoids entirely. Most pipelines and tanks are both coated and cathodically protected, because the combination is more effective and more economical than either method alone.
Yes. As a family-owned cathodic protection distributor serving the industry since 1986, Advance Electrical helps corrosion control professionals identify and source the right materials for their systems.
