One of the first thing that comes to your mind after hearing the term “corrosion” is corrosion of a metal. Corrosion is a basically harmful phenomenon, but it can be useful in some cases. For instance, environment’s pollution with corrosion products and damage to the performance of a system are among its harmful effects, whereas electric energy generation in a battery and cathodic Cited by:

Cathodic protection is employed intensively on the steel drains in oil and gas industry. It is a technique of prevention against the corrosion which transforms the structure into a cathode of a. A common application of internal cathodic protection is water storage tanks and power plant shell and tube heat exchangers.
Galvanized steel. Galvanizing generally refers to hot-dip galvanizing which is a way of coating steel with a layer of metallic zinc or tin. Cathodic Protection Basics. The first application of CP dates back tolong before its theoretical foundation was principle of CP is simple.
A metal dissolution is reduced through the application of a cathodic current. Cathodic protection is often applied to coated structures, with the coating providing the primary form of corrosion protection.

Electrochemistry is a branch of chemistry dealing with chemical changes that accompany the passage of an electric current, or a process in which a chemical reaction produces an. cathodic protection principles be understood (2).
Cathodic protection has been widely used for protecting structures from corrosion. The design of cathodic Protection systems normally relies on a combination of experience, experimental data. However, problems and failures of cathodic protection systems not only has an economic cost, it. Vandervelde Protection is active in the cathodic protection (CP) for all possible applications.

An intermittent impressed current cathodic protection technique using photovoltaic energy was evaluated to determine it`s ability to protect bridge concrete piles in marine environments against corrosion. The technique uses commercially available anode systems to deliver the cathodic protection current to the concrete and onto the reinforcing.
Takeaway: Commonly used to protect numerous structures such as pipelines, ships, tanks and offshore oil platforms, cathodic protection works by allowing a more reactive, sacrificial metal to corrode instead of the protected metal. Corrosion is a naturally destructive phenomenon that occurs when some metals are exposed to the : Krystal Nanan.
