In a piping system that will have 36% HCl ran through it and then purged with air and then 6% HF run through at ambient temperature, would you expect any issues using C276? Or possibly another alloy? I am thinking C276 just because its resistance to HCl but not so sure with the HF, I know it is not as resistant to HF but my concern is with any residual acid that is left over during the purge. Anybody have experience with a system where two different acids are ran through the same piping system.
