Cathodic Protection for Pipelines
Why do buried pipelines suffer from corrosion?
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.
