We do 100% PAUT and MT inspection as well. The visual inspection is on top of that.
I think the next course of action will be to take sufficient samples from the field with varying levels of corrosion and perform destructive testing/examination. I am especially interested in getting these cross...
Stress,
That is exactly what I am trying to do. I was secretly hoping an organization like DNV/ASME/API would have done the research and developed industry guidelines like they have with ASME B31G or API 579.
The NO-GO gauge is not effective here because as some noted, they don't work with non-uniform material loss. In our case, the corrosion along the length of the thread usually occurs bad/good/bad/good/bad where the bad threads on the ends I don't really care about as we have always assumed they...
Stress,
Definitely in agreement with you here. I actually wrote several versions of such a procedure to do exactly what you suggested. Part of the problem is we often see a lot of what I am going to term minor pitting that is pretty well dispersed throughout the thread length but the threads...
Does anyone know of any publicly available standards, recommended practices, documents, studies, etc. that address the inspection and disposition of corroded threads on in use equipment? We are in the process of writing our own criteria and are looking to see what information is out there that...
