Double Wall Tank Annulus Covers
Double Wall Tank Annulus Covers
(OP)
Is anyone aware of a limitation for the size of double wall tank that can have a roof over the annulus space. This may go into NFPA 30 and I am caught between a customer and an engineer. The enginner says that there is a 20,000 gallon thresshold for tank with a covered annulus.
Thanks for the consideration.

Sending sketch or indicating specialized vendor would be helpful
I am dealing with a double containment tank , with a cover above the annulus.
The inner tank has a dome roof and I have no question there.
Thanks
