Ester corrosion of carbon steel
Ester corrosion of carbon steel
(OP)
I have a vessel encased in ASTM A-516 Grd 60 carbon steel. If I were to pump an Ester through it (at moderate speeds and temperature) and also pump filtered air (no moisture removed), should i expect significant corrosion within a reasonable timeframe?

Looking on NACE Corsur i've found, sulfonic acids corrosion data for Steels, Carbon/ Low Alloy. For concentration in the range of 5 – 35 % and temperature 25 – 75 °F the corrosion rate is >50 mpy.
This is just an indication, in your case it depends on the operating conditions and fluid concentration. The ester with humidity can give an acid in you conditions?

In general, carbon steel is not a good idea for acid duty with no inhibitor. While uniform corrosion rates might be accounted for using a corrosion allowance, localised corrosion can lead to rapid perforation of your vessel.

and click on corrosion handbook, i've not checked but probably there is also the sulfonic acid.
Regarding corrosion rate for carbon steel i've never found a free database, the only data that i've found are on the Corsur Database of NACE that you can access on the Knovel website. Probably unclesyd is right and you have to select a more resistant materials like SS 316L.
