Hi all,
I'm not sure if this is the best Forum for the question, so please tell me if you know of a better one.
We have a burried pipe in a tank farm, that is protected with local cathodic protection. As such there are no Isolation Flanges to the attached storage tanks.
We want to assess the coating integrity of the pipe. In a typical CP-protected pipe we would use CIPS to do so. But since our pipe is not electrically insulated from the neighbouring structures we were advised that CIPS won't work. We want to avoid shutting down the line, and opening all the flanges. The pipe is not piggable, so that is also not an option.
Do you know/have experience with other techniques for assessing the coating integrity untere these conditions?
I initially posted the question in the QC, Inspection & Testing forum, but removed it form there, since it might fit better here.
