Introduction to Cathodic Protection | matcor.com

[@doctorona]

This is the best video on KZbin in regards to basic CP system and it's function. The presenter did an AMAZING job!

[@danielstrobel3832]

That is one of the best presentations for that topic that I've ever seen!

[@abassabdullateef9694]

Thank you so much for making this publicly available.

[@pravoslavn]

Loved your presentation. I have been curious about cathodic protection since I learned 50+ years ago that AT&T protected its buried lead-sheathed cable cathodically. Now I will be going in search of some books which give me the math ! Job well done, thanks !

[@jb4bold]

Nice basic introduction,( meaning no chemistry degree necessary) very well presented, Great to see companies willing to part with with there experience and information so freely, Thank you

[@salmanqaiser6918]

can you or someone explain why we make our structure (electrode) more -ve in potential? As the presenter showed in chart and told that more negative metals tend to give aways electrons easily and hence corrode. A bit confused

[@Wally03]

​@salmanqaiser6918 I'm confused on what you asked but if I got any of it here's that. If you mean why do we flood the structure(cathode) with electrons, it is because of the stadium analogy. If there's many going in, it's hard to get out.

[@zdapperman]

Super... The best technical learning video i have seen till date in KZbin !

[@user-ic9wm1gm8j]

This is gold 👌 Thank you so much!!! I'm been researching all the time about this cause is not only following the prints, as a electrician I love the troubleshooting and the understanding of CP is value resource for industrial electricians that was my first assignment on my first time at the trade, thanks again 🍻

[@zahir585]

Be AWARE about the 100mv shift criteria. It is the difference between the instant off reading and the native reading. not like said in 18:00. thanks

[@michaelporter5745]

Fantastic Presentation, you really know your cathodic protection!

[@josephm.6453]

Every second of this video is very important. Condensed with real life application examples. Great video.

[@rishabhsirvaiya136]

Thanks a lot. I didn't get so easy explanation over the internet. Real time Industrial application is explained in this video.

Very brilliant and on point Cathodic Protection Introduction

[@enigmaticerror]

Such a wonderful and detail presentation. Thank you very much!

[@ahmedelghmati4628]

Thank you for the knowledgeable presentation I'm working on cathodic protection system project for pipeline network and this helped my a lot understand what is needed to be done

[@brucechen8844]

Very impressed presentation! I have a silly question. What causes the loss of the anodes? Thanks.

[@LuisAlbanes]

So from the corrosion point of view, it is advisable to use aluminum cables rather than copper for grounding re-bars of concrete structures?

[@pidgeiam4979]

Thank you very much. Loved the presentation. Very interesting and learnt a bunch. Will watch again for my own learning notes. -Pidge

[@aarongonzales964]

Had to pause not even three minutes in to mention I have gained a lot of information already!

[@tonyoostenbrink7808]

wondering about the efficacy of putting cp on carbon steel screwpiles and galvanized screwpiles

[@kasserole55]

@matcor Hi Matcor -- do you have a reference for the 20mA/sq ft current requirement for buried copper mentioned at 52:37?

[@ghostrunner1167]

This is what i was doing a pm on out in the field at the plant great explanation of cathotic protection.

[@faizanghauri2538]

Thank you very much sir your teaching style and abilities are far better than my teacher for this subject...!!

[@A_struggle2563]

Very easy explanation about CP, my query what about the safety precaution for general public during rains, etc.

[@bradleysmith681]

Wow! What an excellent presentation and instructor!!

[@zrated]

Not sure who this guy is but I would like to know. This is very informative. Learned a whole lot, gearing up for NACE CP-1 in December.

[@yakoubyahiaoui9067]

@zack Hi zack When you have the cp1 test Me too i have a test on next january?

[@yakoubyahiaoui9067]

This is my email :[e-mail] I have also cp1 test next month We can share info

[@carlr22]

In seawater cooling systems on ships, would you rather place the CP at the beginning or the end of the pipeline? You cannot have to much protection.

[@philipchinedu2595]

This video takes on electrolytes and more on the corrosive points,good

[@richardnovio8531]

thank you for this great presentation.. i work as power lineman here in saudi arabia and one problem we have here is corrosion of anchor rod for guy wire of the pole where the transformer and rectifier for cathodic protection is placed . there is a oil well in the area which this cathodic protection protect. what would be your suggestion to protect the anchor rod since cp is already available. is it possible to hook up this cp to the anchor rod using the existing anode for the pipe of the well....

[@patrickbetyounan7235]

Do ions actually migrate from the anode through kilometres of underground resistivities and reach the structure almost instantaneously?

[@tedhuck845]

Electricity travels at extremely fast speeds - far faster than the speed of sound but not as fast as the speed of light. So the answer is yes electrical current does reach the structure, even holidays in the coating kilometers away from the source.

Can cathodic protection be used to inhibit rust on a motor vehicle?

[@kray249]

+John Doe CP can only be used on structures that are underground or submerged, as an electrolyte is required for the application of cathodic protection.

Is MATCOR company has branch in South East Asia or Not? I want go training.

[@MATCORmedia]

+Anan S. Hello Anan, MATCOR does not provide CP training for individuals, although we will occasionally provide basic training for clients or groups, such as the training that we have made available on youtube. For a more formal training we would recommend the NACE Cathodic Protection training and certification program starting with the CP Level 1 training. Please refer to www.NACE.org for additional information.

[@Verdeword]

So an anode sprays electrons onto a cathode, which is material to be protected! Anode is -, repulsing negative charges, while cathode, the + charged side attracts the -e's. Where on the voltage value of the charge voltage should be depends on the respective materials' & immediate environments' chemistry, to be more + or -, yes? Has there been experiments with alloys (MMO's?)of Zinc, Magnesium or Aluminum to extend anode life & what that would do to current needs of equal protection, sort of like stainless steel to H2S, & When installing deep anodes, can one side of the anode be shielded and biased to influence the direction of electron travel?
