Design standards for micro-positive pressure containers
Thread Content
If the design pressure of the storage tank is greater than 18 KPa, which code should be applied? GB50341 or NB/T47003.1? Are there any other standards in China?
SH/T 3167-2012 Steel Welded Low-Pressure Storage Tanks, equivalent to API620
For volumes below 1000 cubic meters, NB/T47003.1 is no problem.
There is also an industry standard, SY/T0608-2006 \"Design and Construction of Large Welded Low-Pressure Storage Tanks\", which can be used as a reference
Thank you, then can a fixed-roof tank be used as well? Not in the form of a head?
For dome tanks, GB50341 should be followed
But in GB50341, the maximum design pressure for pipes is only 18 KPa, right?
OP, it’s up to you to decide on this!
What exactly is the pressure inside this tank? We need to analyze each specific situation individually! Our atmospheric pressure rectangular containers can reach 45 KPA; we use stress analysis methods for verification
