FAQ

Q: What are hemispherical ends?

A: A hemispherical dished end is a specific type of dished end used to manufacture storage tanks and pressure vessels. Sometimes referred to as hemispherical heads or hemispheres, these dished ends have a semi-circular curvature and are shaped like half a sphere.

Q: What is the difference between ellipsoidal and hemispherical heads?

A: For instance, hemispherical heads offer the best resistance to pressure, making them ideal for high-pressure applications. Ellipsoidal heads, on the other hand, are often used when height constraints are a concern, as they have a lower profile than hemispherical heads.

Q: What is the depth of a hemispherical head?

A: The hemispherical head has a simple radial geometry: the depth of the head is half the diameter. With a 47” ID, the required wall thickness is 0.2474”, about half the thickness of the shell. Because the head is thinner than the shell, a standard code 3:1 taper is used on the transition.

Q: Why do pressure vessels have hemispherical ends?

A: Hemispherical ends ensure a more uniform pressure distribution within the vessel. This uniformity is crucial for retaining structural integrity under excessive pressure situations.

Q: Do hemispherical heads have valves?

A: A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.

Q: How are dished ends made?

A: Dished and flanged ends are cold formed by firstly pressing the spherical radius followed by spinning the corner radius and straight flange. They can also be dished only (pressed), flanged only (spun) or conical spinning's.
