Current cathodic protection

Have you ever noticed metal objects rusting used, but not everywhere on other sensors? Rust is the reddish-brown coating that happens when metal breaks down. And then they embarrassingly have a habit of literally rusting into nothing after some time; this is the phenomenon that we call corrosion, and for industries like oil and gas transportation construction it's really calling. Danger such as corrosion that can stop machinery and make buildings unstable, which for humans is quite unsafe. Fortunately, there is a way to prevent this from happening — it is called cathodic protection

When it comes to metal surfaces, the much of they we do in how prevents them stop rusting is by a process called cathodic protection. This SME impressed current is done by sending a negative electric charge through the metal which in turn restricts free flowing electrons from passing out and causing rust. Over hundreds of years it has been on the market and with todays state of the art technology, it is finely tuned to better effectiveness at rust prevention.

Revolutionizing industrial corrosion prevention with modern cathodic techniques

In the past it was done using cathodic protection, which means a scrap of metal that is used as sacrificial anode. In this case it would literally anchor to the protected object, and in a way anchored us into an electrical point. The sacrificial anode corrodes instead of the important object. This procedure had its own drawbacks as well because the sacrificial anode needed more replenishment and this might prove to be a bit of nuisance

This things are sacrificial anodes, what we use nowadays it called impressed current in comparison to than sacrificed anode. What happens here is that a negative electric charge created by a power source gets deposited on the metal one wants to protect. It is much more accurate than the old ways of doing this and moreover can be configured to do specifically whatever it needs that should have to done. So it can be customized to more accurately reflect the unique circumstances of an individual metal and location.
