Moisture Level - Carbon Steel
Moisture Level - Carbon Steel
(OP)
Hi all,
I would like to seek for opinions on the below situation:-
With >80ppmV moisture level, will it cause any corrosion issue to the flowline designed from carbon steel material?
Thanks and Regards





RE: Moisture Level - Carbon Steel
Your question can't specifically be answered with what you've said.
RE: Moisture Level - Carbon Steel
Gremlins to watch out for, when water vapor is present are dissolved O2, CO2, H2S, dissolved chlorides, ammonia, amines - the list goes on..
RE: Moisture Level - Carbon Steel
That is not entirely the case. Demineralized water, distilled water, and even good old potable water can all be corrosive to common piping materials without anything special going on.

All the flavours of water you've mentioned have at least dissolved O2 in it.
Was referring to PURE water
And one more contaminant in water : living microbes cause MIC - microbial induced corrosion, and they enable metabolism with any of CO2, O2, H2S or hydrocarbons in the presence of water.
RE: Moisture Level - Carbon Steel
Are you really saying that the oxygen in "Pure" water would be nonreactove when in contact with iron in steel and thus, a corrosion reaction will not form?
