Stainless steel pressure-rated elliptical head tank – is the strength of the head sufficient? Seeking help from those with experience
Thread Content
Hello, experts. I’ve just started learning design, and I have a storage tank for which I need to determine whether the strength of its elliptical head meets the required pressure standards. Please help me with this. The tank’s dimensions are: ID of 900 mm * 3, height of 700 mm. It uses a standard elliptical head, where the smaller radius is 1/10 of the larger radius; the thickness of the head is 3 mm, and the rim height is 25 mm. The operating pressure for this tank is between -1 and 0.99 bar. The head has an access hole with a diameter of 350 mm at 0°, a feed inlet with a diameter of 51 mm at 90°, a quick-connect port with a diameter of 76 mm at 270°, and a floating joint with a diameter of 51 mm at the center. I hope experts can help me check whether the strength of the elliptical head is sufficient. Thank you
Why isn’t there any expert to help?:
What you’re doing is asking others to do the work for you; it’s not solving your problems or helping you
I just want to clarify the issue. The results I get from my calculations after doing some research keep changing, so I’m hoping everyone can help take a look
I’ve just started learning design, and the first thing to learn is how to ask questions. May I ask the original poster: since you don’t know the medium stored in this tank, its material, or the design temperature, how can you calculate the wall thickness? It is recommended that the original poster take some time to carefully review GB150; the answers you’re looking for can be found there.
Use 5mm; 3mm is too thin. There is a 350 opening
Thank you for your advice; I will take the time to carefully review the relevant standards
You have vacuum operating conditions; 3mm is too thin~ Especially for the cylinder, 3mm definitely won’t work
Well, first I need to study GB150, and focus on the relevant chapters
