Why do buried pipelines suffer from corrosion and why do they need to be cathodically protected?
Buried steel pipelines for the transport of gases and of crude oil, brine, and chemical products must be cathodically protected against corrosion according to technical regulations. The cathodic protection process is also used to improve the operational safety and economics of gas distribution networks and in long-distance steel pipelines for water and heat distribution. Special measures are necessary in the region of insulated connections in pipelines that transport electrolytically conducting media.
Water distribution networks and central district cooling are two main pipeline infrastructure areas heavily affected by corrosion. Korrosionsgruppen AB has successfully been protecting various buried objects for over 30 years.

Sacrificial Anodes for pipelines
Application areas
Cathodic protection with sacrificial anodes on buried pipelines makes perfect sense when a highly conductive soil is available, or as a temporary protection. (e.g. temporary protection when detecting leaks on pipes, e.g. water pipes)
Material Used
Magnesium anodes are essential for protecting buried pipelines from corrosion. As a highly active metal, magnesium provides an effective sacrificial cathodic protection system, ensuring the longevity of pipelines in harsh underground environments. These anodes are ideal for high-resistance soils, offering reliable protection and reducing the need for costly repairs. By using magnesium anodes, pipeline operators can maintain the integrity of their systems, ensuring long-term performance and reducing downtime.
