We have been hearing that Kynar does not hold up well to 93% sulfuric acid but is fine for lesser concentrations. Does anyone have any experience with using Kynar for Sulfuric Acid in such concentrations? Will the piping fall apart?
I tried using Kynar Pumps for 93% sulfuric acid and it was a disaster. As for piping i dont know but I would recomend you research this very carefully before installing any Kynar materials on your Acid piping/pumping system.
Attached you will find the link of Georg+Fischer, they produce plastic Piping, I think you will get the information (chemical resistances) that you need there.
