What is cathodic protection technology？

Cathodic protection technology is a technology currently widely used in the industrial field. It mainly protects metal structures from corrosion by applying a cathodic current to the surface. Cathodic protection technology can not only extend the life of equipment and reduce equipment maintenance cycles, but also greatly reduce maintenance costs and ensure the stability and reliability of equipment. In industrial production, cathodic protection technology has been widely used, and new ones are constantly being introduced, and the technical level is improving day by day.

The development of cathodic protection technology has a long history. As early as the 19th century, some scholars proposed the idea of ​​applying electric current to the metal surface to reduce corrosion phenomena. At the beginning of the 20th century, cathodic protection technology was rapidly popularized and promoted, and was widely used in the military and industrial fields. At present, it has been widely used in many industries such as oil and gas pipelines, water treatment, bridges, aircraft, ships, etc., and the technology is constantly upgraded and innovated.

The technical level of the cathodic protection industry is also constantly improving. As the needs of various industries continue to change and segment, cathodic protection technology is constantly being upgraded and improved. For example, in the cathodic protection of urban water pipes, passive cathodic protection technology has been adopted in recent years. This technology can not only reduce water pollution, but also reduce maintenance costs. In the cathodic protection of buried oil pipelines, new gas corrosion inhibitors have appeared in recent years. By gasifying into the interior of the pipeline, they achieve better protection of the pipeline's all-round anti-corrosion effect.

With the continuous development of society, the requirements for environmental protection are becoming higher and higher, and cathodic protection technology provides a reliable solution for this. In traditional cathodic protection technology, the anode is generally made of lead-antimony alloy, which may produce toxic substances such as arsenic and lead during use, causing pollution to the environment. At present, some new anode materials such as aluminum, zinc alloy, high silicon cast iron, titanium anodes, etc. have been widely used. In particular, MMO titanium anodes avoid environmental pollution and also improve equipment reliability and stability.

The application prospects of cathodic protection technology are very broad. As the demand for it in various industries increases, its technical level will continue to improve, playing an important role in environmental protection for society and ensuring equipment reliability. In the future, we can expect cathodic protection technology to continue to play a role in traditional industries while generating new applications in emerging industries. While the level of technology continues to improve, we should also continue to emphasize safety issues in the application of technology and contribute to the future of mankind.
