Frequently Asked Questions

A sacrificial anode, also known as a galvanic anode, is a metal anode that is intentionally allowed to corrode to protect the main metal structure from corrosion. It works by being more anodic than the structure it protects, sacrificing itself in the process.

Zinc anodes are commonly used in marine environments and low soil resistivity environments to protect structures like ship hulls, pipelines, and offshore platforms. They are effective in low resistivity environments due to their high efficiency and low self-corrosion rates.

Aluminum anodes are lightweight and have a high electrochemical efficiency. They are often used in marine applications, including boats and offshore structures, because they provide long-lasting protection and are cost-effective.

Magnesium anodes are suitable for environments with high resistivity, such as soil and freshwater. They provide a high driving voltage, making them effective for protecting underground pipelines and storage tanks.

Galvanic anodes (sacrificial anodes) corrode to protect the structure, requiring no external power source. ICCP anodes use an external power source to provide a continuous protective current. ICCP anodes are typically used for larger structures requiring more control over the protection current.

A reference electrode is a stable electrode used to measure the electrochemical potential of a metal structure in a cathodic protection system. It provides a constant reference point against which the potential of the protected structure is compared.

CTS offers various types of reference electrodes, including copper/copper sulfate (Cu/CuSO4), silver/silver chloride (Ag/AgCl), manganese dioxide (Mn/MnO2), zinc reference electrodes and MMO Pseudo Electrodes. Each type is suited for specific environments and applications.

The choice of reference electrode depends on the environment (soil, freshwater, saltwater), the type of structure being protected, and the specific requirements of the cathodic protection system. CTS can help determine the most suitable reference electrode for your needs.

A transformer rectifier (TR) is an electrical device used in impressed current cathodic protection (ICCP) systems to convert alternating current (AC) to direct current (DC). The DC output is used to protect metal structures from corrosion.

A transformer rectifier steps down the high voltage AC to a lower voltage AC, then converts it to DC using rectifier components. This DC output is regulated and supplied to the cathodic protection system to maintain the desired protective current.
