    Conc Sulf Acid Damage to Alloy 20??

    @MJCronin nobody begged for you to come post anything so next time I have a "quection" (USE SPELL CHECK NEXT TIME FOR ILLITERACY PROBLEMS) make sure you avoid it and don't bother with your remarks that are absolutely not helpful and a waste of everyone's time. Now get back to work being a waste...

    Conc Sulf Acid Damage to Alloy 20??

    @MJCronin as far as your questions, at the time of the original post, I didn't have pictures of any of this just yet. I do now however. As to why I didn't say who manufactured the gaskets, well that's simple. I don't know who the manufacturer is because I haven't seen the gasket. This work...

    Conc Sulf Acid Damage to Alloy 20??

    @mk3223 yes there are two different leak locations. The one this post is about was an area that didn't make sense to me at the time but I think I'm narrowing it down. The second is right at check valves which I believe the BFW is working at a higher pressure and mixing with the acid and...

    Conc Sulf Acid Damage to Alloy 20??

    @edStainless that is what I am assuming is that it started as a crevice corrosion because it's the only thing that makes sense to me as of right now. It's absolutely possible they were contaminated at installation but I won't know for sure. Now I went this morning and examined the flange...

    Conc Sulf Acid Damage to Alloy 20??

    It's all Alloy 20 material. Valve bodies, valve trim, gaskets, pipe, everything that I have information on anyway. I haven't been able to get really into the valve itself and see if some other material is used in that particular valve that would be weak link yet. Gaskets are alloy 20 IR with...

    Conc Sulf Acid Damage to Alloy 20??

    Thank you for the response and yes I don't put a lot of faith in those things that I put as far as operating temp and material. That's what everything is supposed to be anyway that's why I put that in there. About the water, I was just meaning for this specific location, it's not right up...

    Conc Sulf Acid Damage to Alloy 20??

    Just wondering if anyone else has or is experiencing corrosion of Alloy 20 gaskets with 93% sulfuric acid? Had a valve flange and gasket get corroded away in a deadleg right off of the acid tank far away from any water getting to it. All material is Alloy 20 and the deadleg is from the middle...
