API 650 - Max internal pressure above liqu
API 650 - Max internal pressure above liqu
(OP)
I need some help, I am a bit lost , please....I shall explain:
I always though that for API 650 the maximum internal pressure is 2.5 inches water column or 25 psi!!
( by the way is it GAGE or ABSOLUTE ??).
1/-Is this limit of 2.5" water column correct ?
If pressure is a higher then above One has to use appendix F.
And also watch out the vertical component due to this pressure ? Pressure * Tank section area.
-----------------------------
2/-I have seen lately an API 650 tank data sheet with
design pressure = 1013 mbarg ( gage (
This is equal to 210 psig
Is this normal or is there a mistake in my interpretation
This > the 2.5"water column or not !!
Thanks

1 bar = 14.5038 psi
You need to re-evaluate your conversion and decimal point location. Perhaps you mean 1.013 mbarg and not 1013 mbarg? 1.013 mbarg would give you about 0.41" WC.

You are right...thanks a lot

Where will this pressureized equipment, that you have been working on be installed ?
I live in Western Pennsylvania..... will it be near me ?
