To all,
I am aware of the 2.5 to 15 psig pressure design limits for tanks designed to API-620.
What are the practical pressure and diameter limits for flat bottomed tank design ?
At what combination of pressure and diameter make a flat bottomed tank unecononomical and make a tank with two dished ends a better choice ? (assume carbon steel at ambient temperature ?
For example, assume a 12 foot diameter tank, 33,000 gallons designed to 14 psig......is an API-620 design (flat bottom) or a "non-coded" ASME-VIII design (horizontal with dished heads) more econonomical ?
Is there some general criteria that could be used/shared here ?
Thank you for your input....
