Pipeline Under Deposit Corrosion

Pipeline Under Deposit Corrosion

Pipeline Under Deposit Corrosion

Dear All
Whilst there's strong evidence that pipeline deposits lower the inhibitor concentration and coverage, I am curious to see evidence of field experience supported (not laboratory )corrosion rates for under deposit corrosion under the following :
1. Export Condensate with no threat of MIC (so purely under deposit driven)
2. Combined MIC and under deposit corrosion.
3. Under both scenerio, the velocity of the condensate is low (<1 m/s)

I realise that indeed many other factors come into play, but curios to see any decent published field experience which assumes corrosion rates.

Many thanks

RE: Pipeline Under Deposit Corrosion

NACE Corrosion 2012, Paper 1379 might provide the first stepping stone.
