"Cathodic protection – corrosion control for embedded/immersed structures"

In everyday practice we meet many owners of the immersed steel pipelines and tanks who doubt whether to apply cathodic protection system or not…

There’s no doubt about it!

Those without cathodic protection system change their pipelines after 4-15 years, while the pipelines of those who have CP system last well over 50 years, not to mention the savings seen as less product losses, better flow and higher work safety. There is less investing in cathodic protection system than in new repairs caused by corrosion.

When deciding on cathodic protection application, you decide on people’s safety and environmental protection. "YES" is an answer in the line with sustainable development strategies.

REHABILITATION OF HEAT TANKS WITH “SMART” CATHODIC PROTECTION

logoFor the purpose of heat tanks attacked by the severe corrosion rehabilitation, an active cathodic protection system has been chosen. System is precisely designed as a summary of historical data, empirical datasets and physico-chemical analyses. In a term of permanent integrity preservation, a cathodic protection system is designed for complete life cycle. Assessing the risks and having in mind that tank is closed space under raised pressure and temperature where replacement of components is not an option, and also that life cycle is next 30 years, a “three level safety” concept has been established. Paper will present design philosophy, measurement results in steady state operation, statistical and mathematical evidences that system operates successfully, and particularly possibilities of further development of “smart” systems that will be able by themselves to compute the results and even to bring decisions.

KORMAT 2016

IMG_644422nd International Conference of Materials Protection and Industrial Finish “KORMAT 2016″ was held on 20th of April. Conference shared new experiences in wide spectrum of corrosion protection techniques. In our field of expertise especially interesting was debate on “ER” corrosion measurement technique, a new approach that takes place in Cathodic Protection industry. Corrosion rate in mm/year does not replace polarization potential as main criterion, on the contrary it emphasise evaluation of Cathodic Protection effectiveness.
