Stainless Steel Steam Condensate Tank

[SDPoolePE]

I am replacing a lined carbon steel steam condensate tank and would like to use unlined stainless steel. The condensate is at 200F, contains chlorides, and the pH varies. I am considering using 2205. Does anyone have any recommendations for this application?

Could you provide more information on the expected (actual) chloride ranges and the pH ranges in service?

Nice talking to you Scott.

The porblem with this condensate tank is that they use steam for everything in the plant. Where ever there is a leak they pick up contamination.
If it was just some high Cl and low pH, I would look at lean duplex and try to save some money. What worries me is the chance for some solids (mud) to build up and lead to under deposite corrosion.
Considering 2205 for this application looks like a good option. There is also a wealth of fab experience from pulp and paper work in this alloy.

Corrosion never sleeps, but it can be managed.
