CS pipe for a H2O saturated gas stream, 20 ppm chlorine?
CS pipe for a H2O saturated gas stream, 20 ppm chlorine?
(OP)
Colleagues
The tittle summarize the question.
Is it reasonable to use Carbon Steel in a pipe for a gaseous stream, saturated with water, containing 20 ppm of chlorine? Other gases that are present are inert from the point of view of corrosion, like nitrogen, methane, etc.
How many mpy's of corrosion can be expected?
Thanks in advance for your thoughts.

Will there be any wet walls in the piping?
My assumption is that if there is water anywhere it will be Cl saturated. Not good for CS.
I can't find my Compass Corrosion Guide to check, but it sounds bad to me.

Corrosion never sleeps, but it can be managed.

So, it will be interesting to know what would be the maximum corrosion rate that can be expected. A corrosion curve could help.
Internal protection of the pipe?

contains information on piping materials for chlorinated water. The data reported is for saturated conditions at various temperatures, which could occur over time in your piping system. Carbon steel is not recommended for this service because of a predicted penetration rate of > 50 mpy.
