"Cone-roof" versus "dome roof" tanks
"Cone-roof" versus "dome roof" tanks
(OP)
To all,
With regard to API-650, flat bottomed storage tanks....
I am aware that API-650 covers tanks with internal pressures to 2.5 psig...and
I am aware that a domed roof configuration is somewhat more expensive than a cone roof and is frequently used for liquids with slightly higher vapor pressure than water or fuel oil....
By what objective criteria should I recommend use of a "domed roof" storage tank over a "cone-roof" configuration ?
Is there a recommended vapor pressure based criteria ?
I have asked this question on several enginerring bulletin boards and have only recieved vague feeling and recollections. I have also reviewed Phillip Myers "Storage Tank Handbook" looking for an answer to this question
Is there any in-house company based criteria developed that can be shared ?
Thank You.....
MJC

RE: "Cone-roof" versus "dome roof" tanks
Domed roof construction is also used on mid size (diameter) storage tanks- this construction can reduce the mass (& cost) of roof structure support requirements - again it is a designers choice.
The design of the roof construction is usually based on API 650 recommendations, i.e. internal pressure limitations, etc. - as few designers are willing to undertake the responsibility of "independent" design.
