VERTICAL MIXER TANK DESIGN

[401laurent]

Hi,
I have to design a vertical S.S tank ( 8'(dia., 30' H),
supported on skirt or legs. for milk , insulated .
for heads, I want to use fabricated conical with knuckle .
could some one response to theses questions please:
1- witch standards can I use.( I know API650, but this consider only vertical tank with flat bottom )
2- How can I calculate the thickness of the bottom heads.
3- I have used Compress program for ASME tank, and I consider that my design pressure is only atm. (=0), and a btm conical head with knuckle =6%, and the thk calculated is 5/8 po. witch is in my opignion very heigh, because ,in ASME code the safety factor (S.F) is about 3.5, and in other standards may be it less.
to confirm this statement?
4- How to design the legs if I want to welds them to Btm Head.

Thanks you.

401laurent,

I recommend using a skirt in your case. A skirt will impart much more rigidity than legs. With a mixer, you will need the rigidity.


Good luck,
Latexman
