not knowing some details such as temperature, I would say glass-lined.

Your one word answer is: RUBBER.

The stadard material of construction for 70% Sulphuric Acid storage tank is Lead lined Carbon Steel. I have found this used in running Chemical Plants in the past.

But it is also possible to use HDPE or PVC in the present age of other more versatile materials. These materials will not react with H2SO4.

I used to work for a large lead acid batttery manufacturer. They used fiberglass tanks. You could see the fibers through the tank.

Advice may also be obtained from local suppliers of this material, as they will be up-to-speed on best practice.

What is the tank made of may not need to be lined.

FEP ( a form of Teflon fluoropolymer ) is often used for lining of tanks with highly corrosive materials.

The liner is a thick FEP fim , perhaps .125 inches thick, bonded to a knitted fiberglass fabric. The knitted fabric is used to adhesively bond the material to the tank wall. The two layer material , sometimes called Armalon uses a knitted fabric so it can be stretched to fit any contour of the tank . After the adhesive bonding , the FEP joints between sheets of Armalon are thermally welded together to form a seamless lining of FEP Teflon.

This installation is usuall done by a trained crew...not a do it yourself job.

this is a European company, but I am quite sure that they have a US agent (who installs)

Note that FEP is a generic name for a fluoropolymer. If DuPont makes it they call it FEP Teflon. Other companies make FEP but they cannot use the Teflon trade name

Donot coat the internal shell and the internal upper bottom of the Sulphuric Tank with any coating, but instead use an electrochemical technique for Anodic Protection of the tank internally, forming a passive film inside which in turn protects the tank from corroding from inside in the presence of concentrated H2SO4. This technique is also termed as Anotection.

If I am not mistaken, LEAD is used for as a internal liner for large sulphuric acid containers. Lead Acid Battery manufacturers could confirm if this is true.

Tanks made of Fibre-glass Reinforced Plastic ( FRP) can also be used provided the tank size is not too big. This material has fibre-glass net embedded in Epoxy resin and is used extensively in many chemical industries for ducts carrying corrosive vapors and also for smaller tanks to store corrosive liquids.
