storage tank for sulfuric acid! immediately
(OP)
Please, can anyone help me???
Which kind of metallic materials are suitable for realizing a storage tank for diluited sulfuric acid?
Thanks a lot

You can use two component polyamide adduct cured epoxy painted carbon steel shell for the storage of dilute sulphuric acid. If the temperature is aroun 65-70 degree C, you can use GFRP (Glass Fiber Reinforced Olastic) tanks as well. Depends on your economics. The former is cheaper butrequires regular maintenece, whereas the latter is costlier but minimal maintenance.

What do you mean by dilute?
What is the acid temperature?

www.viatec.com visit this site for one source of design and manufacture.
you will need to be specific on the concentration and temperature of the sulfuric acid - straight RTP can handle concentrations up to ~ 70% at relatively low temperatures (100F comes to mind but if you check out www.derakane.com or www.ashland.com you may be able to narrow it down better).
good luck

For moderate temperatures and tank size, your least expensive tank is cylindrical, flat-bottomed polyethylene. Same material as 55-gallon drums used for 93% sulfuric.
For small tanks, molded polypropylene is slightly better than polyethylene and can handle higher temperature.
For higher temperatures and larger tanks, you already have lots of good suggestions for reinforced plastic tanks. Use vinylester resin (not polyester) if choose FRP.
Of the metals (uncoated) mentioned, I have used all (except monel) plus silicon bronze and titanium in various sulfuric solutions and would not use any as a tank. 316L SS is maybe suitable if lots of oxygen (aeration). Copper can only be used if totally air- and oxygen-free condition. Aluminum, you cannot not use any high strength alloy, only high purity Al; it will form a protective sulfate smut. Titanium and Hastalloy C are OK for dilute solutions. For critical applications, zirconium has excellent chemical resistance; my company uses for heat exchangers.
For coated steel tanks, vinyl is good for low/moderate temperature (to ~150 F) and some grades of Hypalon are good up to 300 F. I believe Hypalon is the lining used in railroad cars for shipping hot sulfuric.
