Stainless steel tanks

My vineyard has matured and the crop this year exceeded my carboy capacity. I am able to trade services with a welder who can manufacture stainless steel tanks. He says that he can obtain steel tubes up to 15 inches in diameter which would make the job easier and since I am mostly looking for 100 liter tanks, these would work. If my math is right a 15"x96" tank would be around 92 liters(24.5 gallons). The question regards the composition of the stainless steel tubes for wine making as there are different grades according to the alloy. Do manufacturers of stainless steel tanks use a specific grade of steel? Is there such a thing as food grade steel?

My math is off. I used an online calculator for a cone rather than a cylinder. 15"x36" tubes are closer. I think. Am not a math whiz.

To answer your question - Yes there are food grade stainless steels.

Doubl,

I plan to have the tanks with floating lids for variable capacity or if with fixed capacity I would go with nitrogen gas to top off. I have heard that plastic barrels oxygenate the wine over extended periods(and sellers of these barrels will tell you that's a good thing- when you have lemons, right?). I have 3 6-gallon, 15 5-gallon and 4 3-gallon carboys with 5 1-gallon jugs on the floor right now and it is becoming awkward to deal with them. I have 5 cultivars in the carboys that I want to blend and even with the 5 5-gallon carboys I have left empty, I can't blend with any consistency if I want to have say 26 gallons of one blend, 12 of another and 16 of a third. And besides, empty one carboy and then you have to clean it right away to reuse it. When you get to this volume, carboys are a pain. That's why I want to go to stainless. If I have 6 or 7 variable capacity tanks I can ferment, age and blend a lot more easily and with consistency. The only thing is, I don't want to have to pay $3000 to buy tanks!
