What Baluncore says is certainly true, but it must be done with care. The constant curvature is only on the spherical portion. If the gauge is too large, it may not be possible to avoid getting onto the elliptical skirt.Baluncore said:
What elliptical skirt, on which head profile ?Dr.D said:
An elliptical dome is a dome shape with a curved surface that resembles an ellipse, while a torispherical dome is a dome shape with a curved surface that is formed by combining a spherical cap with a toroidal section.
Elliptical domes have a larger surface area, which allows for more efficient heat transfer and better mixing of contents. They are also more structurally stable and can withstand higher pressures compared to torispherical domes.
The choice between an elliptical dome and a torispherical dome depends on several factors such as the desired pressure rating, volume and shape of the vessel, and the type of contents being stored. Consulting with a structural engineer or dome manufacturer can help determine the best option for a specific application.
Both elliptical and torispherical domes can be constructed using a variety of materials such as steel, aluminum, and reinforced concrete. The choice of material depends on the specific requirements of the application, including factors such as cost, strength, and corrosion resistance.
Both types of domes have their own limitations. Elliptical domes are more difficult to fabricate and require more precise calculations and construction techniques. Torispherical domes have a lower pressure rating and may not be suitable for applications that require high pressures. Additionally, both types of domes may not be suitable for extremely large or irregularly shaped vessels.
