The diameter of the vessel will be 60"OD. After checking this through, my pressure is 0PSI. I have checked the deflection on the top head and found that a thickness of 1/4" will be acceptable. However, when figuring a water weight of approx. 10,000lbs, I find that the deflection on the bottom...
When designing in Compress for an atmospheric vessel, is it necessary to use 14.7 as the internal pressure? Can I use 0psi? Also, does Compress take into account the actual weight stress from the liquid or do I have to enter these manually as a vertical load? I want to make sure that the...
When designing a Flat Head vessel that will be atmospheric and ambient, what should I use as the design pressure? Technically speaking atmospheric will be 14.7psi, but if I use that in lieu of 0psi, the vessel will require a 1.25" plate. This vessel will have a 1/4" shell, and be supported on <...
I have a customer that has recently purchased some large silos with the intent on using them to hold liquid fertilizer. These silos originally were used to hold grains. The size of these vessels are as follows: 44' wall length, 12' diameter, 3/16" wall thickness. Original material had a slight...
Is there any design considerations to take into account when attaching legs directly the bottom head instead of attaching them to the shell. I want to use either channels or angle supports to attach the legs to the head. The vessel itself is an API 650 tank that is atmosperic.
I was wondering if API 650 code can be used to store diesel fuel. I always see oil storage references but never gasoline or diesel fuel. Are there any special requirements for diesel fuel storage?
When designing a pressure vessel with 4 lifting lugs, what is the safety factor for each lug. I have read that it should be 5 to 1 of the empty weight, meaning that each lug should be able to withstand the entire weight of the vessel during lifting. Is this overkill? This tank is not an ASME...
