What is Cathodic Protection ?
For those unfamiliar with the basics of corrosion prevention here is a short rundown.
Cathodic protection (CP) is a technique to control the corrosion of a metal surface by making it work as a cathode of an electrochemical cell. This is achieved by placing in contact with the metal to be protected another more easily corroded metal to act as the anode of the electrochemical cell. Cathodic protection systems are most commonly used to protect steel, water or fuel pipelines and storage tanks, steel pier piles, ships, offshore oil platforms and onshore oil well casings.
Impressed current Cathodic Protection (ICCP) systems use anodes connected to a DC power source (a cathodic protection rectifier). Anodes for ICCP systems are tubular and solid rod shapes or continuous ribbons of various specialized materials. These include high silicon cast iron, graphite, mixed metal oxide, platinum and niobium coated wire and others.
A typical ICCP system for a pipeline would include an AC powered rectifier with a maximum rated DC output of between 1 and 50 amperes and 50 volts . The positive DC output terminal is connected via cables to the array of anodes buried in the ground (the anode groundbed ). A cable rated for the expected current output connects the negative terminal of the rectifier to the pipeline. The operating output of the rectifier is adjusted to the optimum level to ensure adequate protection of the structure.
