Hi @DSTankee and JStephen,
I just need your help regarding interpretation of the clause F.4.1. I am just confused when I calculated the P_F4.1 the design pressure is around 33 kPa and then the std is up to 18kPa only. I'm really confused about this pressure. Hope you can give me explanation...
@DSTankee, Since the diameter is 8m only, it will fall on the sub-category 5.10.2.6 (d) for anchored tanks of any diameter. Still, the requirement of 5.10.2.6a shall meet. Please note that this tank has 10 nos of anchor bolts.
@DSTankee could you elaborate more why detail i is not conformance with frangibility? As per datasheet the tank is equip with 30in emergency vent. In that case, frangibility is not required? Thanks
They mentioned this:
Tank design calculation shall include verifying the failure pressure on top shell/ roof
connection and Bottom shell / annular connection. And make sure the failure pressure on
top connection is less than the bottom connection. The tank has a 5.6KPa/-0.5 Kpa design pressure.
Hi Everyone,
Good Day!
I have this tank project (8m Dia x 13.95 Height) Dome Roof Tank. My question is, Client requested to make it frangible connection. Does this applicable to this tank size? Roof to compression bar connection is as as per detail i of Fig F.2. Kindly help me on how to...
Hi I would like to seek your help. I am doing a design for caustic scrubber vessel. Before the vessel is using a reinforcing pad but now the client opted to change it to insert plate. The nozzle size is 16"and it's located on the cone section of the vessel. My question is how to consider the...
Hi sir @LittleInch, thank you for your inputs.
Just I mentioned earlier, the tank has a nozzle in the cone roof as below :
1. Breather Valve (equiped w flame arrestor and Inlet isolation valve)
2. N2 blanketing
3. VOC outbreathing
4. Blanketing valve pressure pilot.
Like I said I also have...
Hi sir @LittleInch. Thanks for your input. I did increase the compression ring almost come up with 250x250x28 angle bar. And also increase my shell thickness just to pass the warning.
Please be informed that my ametank don’t have the floating roof features thus I dont have any input related to...
Dear sir @IFRs, AmeTank required 26min no. of anchor bolt, so I did add anchor bolt. Still the warning persist. I got some red warnings in my top angle (please see attached file) and I tried to increase the size. I also checking the Annex F of the API 650 especially the decision table but I...
Dear sir @IFRs, thank you for your inputs. My AmeTank doesn't have a floating roof feature so no input with floating roof details.
What I did is I inputted the design condition stated on the datasheet- into the AMETank. I adjusted the shell section specifically the shell thickness. I got 6...
Hi sirs,
I would like to seek your help. I am designing a Cone with internal floating roof tank which has a 22.94m ID x 14.52m H. Following information's also were indicated.
Design Pressure = 250mmH20 + Full Liquid
Design External Pressure = -60mmH20
Design Temp = 70 Deg C
Liquid Stored =...
