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.

Advantages
Sacrificial Anodes
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)
