Join your peers on the Internet’s largest technical engineering professional community. Below is the statement: Are you an Engineering professional? Few production environments have the luxury of ordering new equipment to replace existing machines on their rpp floor.

The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs. What has been done looks like two calculations, picking the biggest number. So you consider the influence of the coating for the first 3 years and for the remainder, calculate without it.

So the point is basically that you need two sets of design lifeone for CP sytem and the other for the coating you apply to the structure. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Another factor is periodic cleaning of marine growth in this zone. The effect of marine growth is highest in the upper 30 meters where wave forces may further contribute to coating degradation. Click Here to join Eng-Tips and talk with other members!

Close this window and log in. You should size the anodes based on an assumed amount of coating damage and a anode lifetime.

The Eng-Tips staff will check this out and take appropriate action. You probably should also know what b is. Do let me know if you need any clarifications. So this lead to increased demand on the number of anodes and the design current etc.

I’d say that if you don’t know a, b and t, you should not be trying to use equation 3. I am hoping someone could elaborate the following part, ‘When the design life of the CP system exceeds the actual calculated life of the coating system according to 6.

As a simple engineering approach, fc can be expressed as: Kind regards, Sadik Hussain. It’s easy to join and it’s free. But over the last few years Coatings have been found useful in contributing positively to the CP cause which led to a considerable reduction in the usage of anodes.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. That’s what you want to do? What’s the point in having anodes lasting longer than the coating? Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration.

I think the Cathodic Protection Systems were designed previously without considering the influence of coating on the corrosion behavior. Ideally you would like both durations to be similar since it is beneficial to replace them together.

But then how do we calculate t if we don’t know f in eq 3. Biginch, Yes it would be preferable if you size the anodes based on the coating life. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

It appears that you need to know a and t to do this problem. But sometimes Owners tend to specify different durations say 5 years for the anodes and 3 for the coating.
