Zero Corrosion for Sulfuric Acid?
Zero Corrosion for Sulfuric Acid?
(OP)
I need advice on selecting a material that will not experience corrosion from sulfuric acid. All concentrations with working temperatures of -100 to 200 degrees F will be experienced. If velocity of the fluid is an issue, assume 300 mm/s.
Thanks!
Thanks!

I am aware that some glasses may do the job, but I wanted some clarification from people who have some experience with corrosion engineering. I would prefer a metal if it is an option at all.
Thanks

After you enter the site, locate the Technical Series article No 10057. This article provides a comprehensive explanation of stainless steel and ni-bearing alloys for sulphuric acid service, the paper is titled;
"Selection and performance of stainless steels and other ni-bearing alloys in sulphuric acid".

This application requires a flexural mechanism, and this was my primary motivation for examining metals. However, the difficulties of using metals in this case may certainly justify a different approach. The pressure in this application is less than 50 psi, so I am sure that polymers will work well.
Where might I find resources on selection of a polymer. Perhaps more important, I will need to find information on seals.
