Calculation of Tank Wall Thickness
Calculation of Tank Wall Thickness
(OP)
Hi,
Can anybody help on the calculation for the wall thickness of a storage tank 98"OD x 216"straight side? The SS304L tank is vertical with cone top and flat bottom at atmospheric temperature and pressure to hold 67% HNO3 (1.41kg/l or 11.7 lb/gal). We had a proposal with 10gauge SS304L for this tank. But not sure if it is safe for tank with this height. Highly appreciate your advice.
Thank you!

If you use 12F, please use a 'doghouse' shaped manway, not the rectangle 12F recommends. The square corners at the top of a 12F manway generate the highest spots of stress in that tank. I have had multiple cases of Stress-Corrosion Cracking from those square corners.

Manways, side and/or top, appear to be required to me.

What about your State of Ohio and your Insurance company requirements ?
While a "homegrown" tank design may not fail, it will be hard to prove that it is safe.
Storage of deadly/dangerous liquids may require a design certified to be in accordance with a nationally recognized Code or Standard.
NFPA-30 requires tanks that store diesel fuel to be in accordance with a UL, API or ASME code. Is your liquid less dangerous than diesel fuel ?
Yes, storage of large amounts of deadly liquids in API-650 stainless steel tanks is expensive.......
