Pressure-bearing issues of stainless steel elliptical tanks
Thread Content
A 3 mm thick stainless steel elliptical tank, with a capacity of about 100 L. Can its inner wall withstand a positive pressure of 4 kilograms of compressed air? Only the tank body is considered, without taking into account the head, manholes, seals, etc. I’m a newcomer; I hope the experienced members here will be kind enough to offer their guidance.
Pressure vessels are special types of equipment; one cannot guess their parameters arbitrarily. Please have a professional carry out the calculations, as these depend on factors such as pressure, temperature, the medium used, the diameter of the vessel, and any openings present. Besides, you said the elliptical tank is very small – do you mean an elliptical head tank?
The poster can use the non-circular containers in SW6 software for calculations
Estimating the cylinder using 325/377 seamless pipes gives sufficient strength, but if it is to be actually constructed, it is necessary to find a qualified company to handle the design, fabrication, inspection, and installation.
Why must such a small jar be made oval?
It might work, or it might not. For example, 50/75 will be fine. If it’s calculated using a 500/750 standard, it won’t work ； The original poster didn’t provide any meaningful dimensions for the ellipse’s volume, so it’s impossible to calculate it. Please also specify the geometric dimensions so that I can carry out the calculation for you.
