Hi all,
Although I had done some scratch calculations myself, I asked our mechinical department to do it "officially" and they have come up with the same result that I did. The vessel can easily withstand full vacuum and will just have to be rerated for FV.
Thanks for the replies...
Thank you guys for all the expert comments. I have decided to go ahead do some calculations to find the maximum external pressure it could withstand using ASME formulae.
Still one of my question remains unanswered, i.e. is there a way to calculate to calculate the maximum vacuum that can be...
Hi all,
we have a vessel (Diesel salt drier) here which is rated for an internal pressure of 110 psig and an external pressure of 2.5 psia. I am sizing a relief valve for this vessel and there are concerns about the vacuum generation on the vessel by a centrifugal pump which takes suction from...
Thanks jcfoley and EGT01 for your valuable inputs. I also remembered something which said that if the volume is below a certain number of gallons, it can be considered as a part of piping and hence won't require a fire protection. Well I think as jcfoley said they may have taken it out during...
Hi,
Is there any code or guideline which exempts a vessel from having a relief valve sized for a fire case based on volume? I have seen specific companies having a guideline to exempt a vessel from fire case if the volumes contained were less than 15-60 gal. I have searched through all I could...
Hello,
Has anyone come across the above mentioned type of valves. One of our petroleum industry clients is using the flexflo valve/regulators as pressure relieving devices. The literature from the manufacturer (Grove/Dresser I guess) also lists that it can be used for pressure regulating...
Greeting!
I have come accross some weighted relief devices, which are more like pressure vents with weights. It lists some different manufacturers like Roots and Metal Arts. All I know is the size (8", 10" etc)and capacities on few of them. They are set below 15 psig pressure. I am confused as...
