What is another name for a flanged and dished head of a pressure vessel?

• A. Torispherical
• B. Ellipsoidal
• C. Hemispherical
• D. Conical

Answer: (A)

In pressure vessel heads, a flanged and dished shape is known as a torispherical head. It combines a shallow curved dish with a flat or slightly curved flange that is welded to the vessel shell. This design provides strong resistance to internal pressure while being relatively easier and cheaper to form and weld compared to a fully hemispherical head, making it a common choice for larger vessels. An ellipsoidal head has an all curved, elliptical profile without a distinct flat flange; a hemispherical head is a full bowl without a flange; a conical head tapers in a straight-lined manner rather than forming a dish. So the term that best describes a flanged and dished head is torispherical.
