Q: I have a high pressure application that exposes my flanges to sulfuric acid? Can you suggest the best flange and material for this situation?
A: For high pressure applications weld neck flanges have a beveled end that, when connected to a pipe, creates a trough for a strong weld which is highly suitable for this situation. In terms of material, this always depends on concentration and temperature and various materials may work from Inconel, Hastelloy, Zirconium and Tantalum (for the most severe).
