Fluorosilicic Acid Compatibility with PVC

[Nalsoft]

Hi,

Going to use PVC pipes for Hydro-Fluorosilicic Acid (20% conc) in a chemical dosing system.

wanting to know if anybody has come across any issues regarding material compatibility.

Thanks in advance

Why not ask the PVC manufactures, surely the best source of information?

Also, 20 seconds to google with lots of info to read.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Use fluoride-compatible materials such as polyvinyl chloride (PVC), chlorinated PVC (CPVC), and HDPE in pipe manifolds.

It's not only the material PVC. PVC is compatible for FSA as per manufacturers. However, the compatibility of the joints/solvent cement is the concern here. There are no clear information available as nobody has done any testings. Does anybody have any experience of using PVC pipes with FSA?
