What is corrosion?<\/h3>\n
Metallkonstruktionen stehen in st\u00e4ndiger Wechselwirkung mit ihrer Umgebung. Kommen sie in Kontakt mit elektrisch leitf\u00e4higen Metal structures are in a state of constant interaction with their environments. If they come into contact with electrically conductive materials like water, soil or other metals, differences in electric potentials produce a flow of current that carries away metal ions and thus erodes the material. This changes the surface of the metal and it begins to decompose \u2013 it corrodes. The material\u2019s properties change in ways that impede its function. Initially, the appropriate paints or coatings are used to prevent corrosion damage, but a layer of paint or a coating can never provide 100% protection against external chemical and mechanical influences. Even the smallest defects in the coating can very quickly lead to major corrosion damage. Cathodic Protection (CP) is the most effective and sustainable way to combat these electrochemical corrosion-causing processes.<\/p>\n
How does Cathodic Protection work?<\/h3>\n
Cathodic Protection generates an electrochemical protective shield that compensates for the difference in the electric potential between the structure and its surroundings. CP falls into the category of what\u2019s known as active corrosion protection and denotes the generation of direct or protective current that is usually produced by an external power source (solar panel or rectifier). This protective current is established between the protected object, i.e. the cathode, and a baser metal, i.e. the sacrificial anode. The baser metal then corrodes instead of the metal facility being protected. This anode bed ensures that current does not leak through defects in the paint\/coating.<\/p>\n
Injecting the protected objects (e.g. a pipeline) with protective current not only protects them cathodically, it also polarizes them, and that enables coating defects (even potential ones) to be reliably detected using special measuring equipment! This is possible because the difference between the values measured at the defects and those measured in areas where the coating is intact is easy to see. Moreover, with the help of remote monitoring technology with continuous threshold monitoring, an operator can immediately see a sudden increase in the protective current required \u2013 usually a sign of a new defect in the coating.<\/p>\n
CP pays for itself quickly and sustainably!<\/h3>\n
Comprehensive corrosion protection is simply indispensible for the safe and efficient operation of pipe networks, utilities, hydraulic steel structures or industrial facilities. And it\u2019s particularly important for the operators of pipelines and facilities that are exposed to greater risk due to gas or other petrochemicals.<\/p>\n
CP pays for itself quickly and appreciably. Installing a cathodic protection system represents only a fraction of the cost involved in repairing the damage caused by corrosion. CP prevents potential commercial losses and reputational damage and it helps enormously in assessing the structure’s condition. CP also helps operators fulfill their environmental obligations.<\/p>\n
