The Cathodic Protection

The method of corrosion control that can be applied to buried and submerged metallic structures is called Cathodic Protection (CP). Usually, it is used in conjunction with coatings and can be considered as a secondary corrosion control technique. Normally a coating system which can be between 50 and 99 % efficient depending on the type, age, a method of installation, etc is the primary corrosion control method on any given structure. A maintained cathodic protection system and a properly designed will take up the remainder resulting in a 100 % efficient cathodic protection system.

Why Does Cathodic Protection Important And What Is Its Principles?

An estimate of 3 and 5 % of the gross national product (GNP) of industrialized countries is attributed to corrosion damage. Almost $300 billion per year of corrosion of metals costs an average economy and it is estimated that one-third of this value could be saved with a better selection of corrosion prevention techniques which includes Cathodic Protection in Singapore. Useful metals are frequently extracted from their naturally existing states as ores to be industrially and commercially viable. But there’s a propensity for these metals to revert back to their initial states (metal oxides) because of their chemical nature. In layman’s terms, the process is often known as corrosion and it’s the most common example notable in everyday life is the rusting of iron and its various alloys.

What Are The Uses And Advantages Of CP?

The ability to be deployed merely by the maintenance of a Direct Current Circuit is the primary benefit Cathodic Protection offers over other anti-corrosion systems. And also the effectiveness of the applied Cathodic Protection can be easily monitored just like the regulated by adjusting the properties of the Direct Current passing through the system. The coatings may have been compromised but it can also work for a hand with hand with Anti-Corrosion coatings. This can be applied also to marine architecture structures to counter the effects of corrosion thus increasing the lifespan of these structures.
