Topic: What's the best material for a storage drum that contains sulfuric acid?

posed by 
I am designing a storage drum for sulfuric acid with material selection as SS 316L. Do I consider any corrosion allowance if the design temperature as high as 120 °C?

    Before attempting to answer the corrosion allowance question one must address whether you have chosen an acceptable MOC for this application. Do you already know that 316L stainless steel is suitable? Sulfuric acid is a tricky chemical to deal with since its corrosivity varies with concentration, temperature, impurities, and velocity; sometimes in unexpected ways. A temperature of 120 °C will most likely be challenging for many MOCs. I suggest you get guidance from a detailed reference that covers sulfuric acid and materials of construction selection such as MTI Publication 1: Materials Selector for Hazardous Chemicals: Sulfuric Acid.

    DEAR Mr. BRIAN, Thanks for your time and brief suggestion. But for an instance, if we suppose that SS 316L is suitable for handling Sulfuric Acid or any other Acidic Media like Corrosion Inhibitors. For that purpose what may the corrosion allowance for storage tank at same designing temperature

    If is industrial acid, concentration 95 % or more, the storage material could be Iron; if the concentration is diluted then the material must be SS 316 or other recommended in the materials guides and standards (Depend of the temperature, pressure, environmental conditions, life time of installations, if is a short time of the installations, could be used PVC or fiberglass ). In extreme cases is used Titanium.
