Hi all,
Can you explain why for aboveground flammable horizontal storage tank Emergency vent sizing considère an allowable over pressure of 35 Kpa (5 psig)in ULC S601, while in NFPA 30 Emergency vent sizing consider only 17 kpa(2.5 psig)?
Also normal maximum operating pressure in ULC S601 state...
Hi All,
I'm designing a small tank with Flat Bottom ( less than 10 ft Diameter) at more 10 psig Presuure design,
So I know API650 is applicable only for max 2.5 psig, and API 620 is for large tank (typicaly more than 300 ft),
the question is can I use API 620 for this small tank?
Thanks.
