Can you simply explain to me what does the "Immersion-grade two-pack epoxy" means?
what does two-pack means here?

How much is the maximum allowable difference between concrete coating and anode thickness?
I heard about some 25mm as maximum...is it allowed?

I asked a question about pipeline pigging which it seems misunderstood!
I know that the ID is finally important matter for pigging, but I don't know which items shall be accounted for?
lets say that the pipeline has two sections with 14.3mm and 15.9mm wall thickness.
so is the ID difference...
To make pipeline piggable, the internal diameter shall be somehow unique along the pipeline. the deviation , as I know, up to some 5% is acceptable for conventional pigs, while 2% is recommended for Intelligent ones.
the question is how the deviation shall be calculated? which parameters shall...
Yes Steve, I know about the scopes and you are right. however, I mean the difference between previous B401 (1993) which was also applicable for pipelines and the new F103 (2003).
does the large difference between breakdown factors is related to improvements in Coating quality?
I found a document...
the coating breakdown coefficients (a and b) in DnV-RP-B401 where in order of 0.1 and 0.01.
these coefficient are remained unchanged in new revision of B401.
on the other hand, the DnV-RP-F103 proposes very different coefficients, which are in order of 0.001 and 0.0001; which leads to very light...
