Sacrificial Anode Cathodic Protection Allied Corrosion

Sacrificial Anode Cathodic Protection
Scene #1:
Metal structures exposed to the environment will corrode over time.
Scene #2:
Sacrificial Anode Cathodic Protection is a method of mitigating corrosion to these important structures.
Refineries - Storage Tanks - Bridges - Pipelines - Oil Platforms - Ships
Scene #3: (Underground view of a Cathodic Protection System for a Pipeline. This scene focuses on introducing the components of a Cathodic Protection System.)
Cathode: In a Cathodic Protection System, the Cathode is the metal structure that we want to mitigate corrosion on.
Soil: The Cathode and Anode must be immersed in a medium that allows ions to flow freely - Earth or Water.
Anode: The Anode a metal that is more reactive than the Cathode, and will donate electrons to the Cathode, causing the Anode to corrode.
There must be an electrical connection between the Cathode and Anode, so that there is a return path for current flow.
Scene #4: (Same underground view of Cathodic Protection System for a Pipeline. This scene focuses on how the components of the Cathodic Protection System work together to mitigate corrosion.)
The moisture in the soil serves as the electrolyte which causes ions to move freely.
Since this is a more active metal, it’s more likely to lose electrons, as a result, corrosion begins.
Negative electrons are forced to travel from the anode to the structure.
As the electrons flow to the cathode, it creates chemical reactions which in turn help mitigate corrosion.
Scene #5:
In Sacrificial Anode Cathodic Protection, no external current source is used. The electric potential difference between the Anode and Cathode are what causes current to flow.
The most common metals used in Sacrificial Cathodic Protection are Aluminum, Zinc and Magnesium.
Scene #6:
The advantages of a Sacrificial Anode Cathodic Protections system are:
#1 - No external electrical current is required
#2 - It is easy to install
#3 - Is it less expensive to install than other types of Cathodic Protection systems
The disadvantages of a Sacrificial Anode Cathodic Protection system are:
#1 - Anode current is uncontrollable, making it more difficult ensure protection throughout the entire metal structure
#2 - It requires frequent monitoring and replacement of anodes.

It is fast but easy to understand

I was watching an underwater welding video and got curious about what purpose the anodes had, thanks for the video!

Thanks for watching!

sick intro

[@dorisatkinson7259]

Cathodic protection is so useful in so many different situations as you list in one of your graphics. However, One of the most problematic items for rust is cars. I didn’t see that on your list. I don’t understand why cathode protection isn’t used for cars all over the place. Is it just not feasible? Can it be added on aftermarket? I understand automakers not wanting to put it in because they make money by making disposable cars that corrode. Thanks for a great presentation.

[@bodyfitnessworkouts7210]

Is there an easy way to crack open the anode cells incase you need to do some repair & mentanaince

[@michaelhart7431]

The anodes are a consumable. At the the end of useful life they are replaced.

[@nasirahmed-ng4ru]

at 1:30 it says, Negative electrons.. . . . . . 🤔do we have any positive Electrons as well then?

[@SubrataRanjanMistri]

Yeah,those are called positrons.

[@aaronhe6877]

Aren't pipelines underground anyway, so the oxygen can't contact it?
