Piping Material for CO2 -60¦F
Piping Material for CO2 -60¦F
(OP)
Hi:
I want to select material piping for CO2 service -60°F@100 psig, liquid. Searchig some information, I found in "Pressure Vessel Handbook" from Megyesy a table, with Chemical Resistance of Metals. With a recomendation that CS is "fair" for use in CO2 (dry) & "Caution" with CO2 (wet). This recommendation means that I have to use a corrosion admisible thickness greater than 1/8" for example or, in othe hand it´s better to use another alloy, like Inconel or Monel.
The proble to use this alloys is the price and long delivery time. I prefer to use another alloy like A333 Gr 3 or Gr 6.
Maybe do you have some recommendation for this application.
B. Regards,
Luis Felipe

Carbon Steel is having Excellent chemical compatibility with the CO2(Dry)
and is having Fair compatibility with CO2(Wet)
as per Cole-Parmer

Thanks for your help. Now I have a better idea about selection of material, now I have another question, how about other super alloys, like Inconel or Monel? This page doesn´t have info about them.

I agree with BigInch, that the price is more, even then I googled and found CO2(Dry) is having excellent comparability with the Monel.

Thanks every body
I am going to use A333 Gr 9 or Gr 9 for CO2 -60F. Now I have one more question about welding, hardness test, heat treatment after welding.
Somebody can help or some guidelines about it.
B regards.
