Welcome
Welcome to cathodic-protection.com, brought to you by Abriox, the remote monitoring specialists. Here you will find information on cathodic protection (CP) and how it's used in the industry.
Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathodic side of an electrochemical cell. The simplest method to apply CP is by connecting the metal to be protected with another more easily corroded metal to act as the anode of the electrochemical cell.
Cathodic protection systems are used to protect a wide range of metallic structures in various environments. The most common applications include:
• Water and fuel pipelines
• Storage tanks
• Ships and boats
• Offshore oil platforms
• Oil well casings
Cathodic protection can, in principle, be applied to any metallic structure in contact with a bulk electrolyte although in practice its main use is to protect steel structures buried in soil or immersed in water.
CP use on Pipelines
Cathodic protection is an important method of preventing corrosion on buried metal pipelines. Every pipeline operator must carry out regular measurements of CP – at transformer rectifiers and tests points (in impressed current systems) and at sacrificial anodes (in galvanic systems).
Collecting and analysing these CP measurements is labour-intensive, very expensive and (more importantly) they can only be reactive – CP problems can lie undetected for long periods, during which the pipeline is insufficiently protected.
Following intensive discussions with pipeline operators and CP professionals, Abriox have developed the MERLIN system to remotely monitor and communicate CP levels.
