i am looking for a vrendour to provide material for cath. protection. pls help if u can
AFIC can provide you all the needs in cathodic protection system
i am an engineer intersted in cathod protection
i am a electromechanical engineer and willing to increase my knowledge about cathodic protections.
it is connecting a metal to a more reactibe metal in order to it from rusting
i’m a stupid mechanical engineer who wishes to rust proof himself against the elements
I need to download (free) a cathodic protection design softwar (is that any help)
Thanks
I am a structural engineer looking for solution to rail foot corrosion taking place under the fittings used to hold rail to sleeper.
I am a corrosion engineer and I am willing to exchange ideas on CP with you. gregc@uj.ac.za
I like this website, very helpful for engineer and designer
Searching for the correct anode material in CP to tests with the Oil & Gas non mag drill collar materials.
We are about to release the sacrificial anode to the field to test the cathodic protection method on the non mag SB P530 material. Studying at some corrosion prevention methods to protect from the corrosive mud environment with H2S formation and others.
Materials concern are the non mag materials, basically SB P530 and P550 SCHOELLER-BLECKMANN, SMFI GRADE:AMAGNIT501 and JORGENSEN FORGE CORPORATION NMS140.
Seems to be a good handout material. Thank you for publishing it for free
it is useful to me for the pipeline cathodic protection study purpose.
I love it because it is goog for my research and teaching in the industries.
i’m an Phisyc Engineer from Universitas Nasional, Indonesia. about this ebook of chatodic i hope there is the another one to be same like this, anyway thank’s for the freesownload god bless you
THE CONDO I am working at ,is installing cathodic protection
induce current . How well does the continuity have to be connected
and what are the ramifications of where it isn’t connected to the re bar how does it effect p t c
thank you,
Bill
plz give material abt designing for cathodic protection
This article is found very informative, thanks a lot.
I want to know more about cathodic protection
I’m Electricral & Instrumentation Technician, from Oil & Gas field. I would like to learn about CP because I’ve to utlize the technique in my career. Thanks for the website.
I am CP engineer at oil fields, like to know more about storage tanks desiging & installation..
Many thanks.

Dear CP Professionals:
We are conducting this survey as part of a research project sponsored by the Oregon Department of Transportation, entitled “Replacing Thermal Sprayed Zinc Anodes on Cathodically Protected Steel Reinforced Concrete Bridges”. Click here: http://www.surveymonkey.com/s.aspx?sm=J1AB3N1c4VH2fLFgBuUyqQ_3d_3d (feel free to forward this to other professionals specialized in CP or coatings removal or concrete surface preparation).
Thank you for taking the time to provide input on this important research, which aims to determine the most cost-effective method to remove existing zinc anodes and to develop a protocol to prepare the concrete surface for the new anode.
Happy holidays!
Sincerely,
Xianming
Actually i don’t have specific comments, but i tried to log in item no.9 under the following topic but i failed.
“Searching for the correct anode material in CP to tests with the Oil & Gas non mag drill collar materials”
Please can i have a copy to be kidly sended to my email of the above mentioned absract which is developed by Mr. Mohamed Edris
Moreover if there is any websites discussing the effect of using sacrificial anode cathodic protection with sour service or even traces of hydrogen sulfide, kindly send me the link.
I am a technical procedure writer and need to put together some procedures for CP regarding operation and maintenance. I will definately use this website for information on CP.

i am a stident of federal university of technology oweeri in the department of materials and metallurgical engineering. i wish to specify on corrosion and this is why i need to know more on cathodic protection, getting the latest technological update and research on the topic. tell me more if u know, you can reach me through my email. i have used several webs but in most cases i used google to search out this webs, but i still need more books(ebooks are not bad)
i have a problem that when we put an earthing rod(3 lenght of 3 meter ) in the solar for cp pipe line unite and coected
the potintial of the pipe line cp go up from -1400mv to -1650mv
iam confused why it hapen pls can you explan
im febricationo engineer and i should know more about c.p. systerms
it very usefull
I am a little confused about Impressed Current Systems. I’ve heard two different things and don’t know which is correct. On an Impressed Current System, do ALL components of the system have to be continuous with each other, or do they only have to be continuous with themselves? For example, if a site has two tanks with piping, one regular and one super, does the regular tank and piping have to be continuous with each other? Or if they are both continuous with themselves, meaning all the tank and piping for the regular is continuous, and all the tank and piping of the super is continuous with itself, but the two are not continuous with each other, is that still ok? Any help in clearing up my confusion would be greatly appreciated.
im facing problem in our gls tank for sewage treatment plant, because internal structural is rested ,there was cathode protection may it 10 years old , we install new one same but i failure to prevent from rust ,can u help me ,what i have to do???
i’m a student of applied chemistry & chemical technology and i need this corrosion protection
Can anyone send me free access to the BS 7361-1:1991 cathodic protection
Best regards
