Corrosion issues with mixed acids
Thread Content
Does a mixture of 98% concentrated sulfuric acid and 65% concentrated nitric acid corrode stainless steel at room temperature? If there is any, what material would be better!
Using a carbon steel lining with PTFE or another type of adhesive can solve the problem.
It is better to use steel skeleton composite pipes when the temperature does not exceed 100°C
The fluoroplastic-lined pipes we use are still fine for now
PTFE lining can handle temperatures of 150°C; for 180°C, PFA lining can be used, and for even higher temperatures, Hastelloy should be considered
If the temperature exceeds 200 degrees, use zirconium materials directly; it’s just a bit expensive
