Summary Introduction Hemispherical Heads - Horizontal Vessel Semi-Ellipsoidal Or Elliptical Heads - Horizontal Vessel Torispherical Heads - Horizontal Vessel Bumped Heads - Horizontal Vessel Cylindrical Section - Horizontal Vessel References The semi-ellipsoidal heads are shallower than the hemispherical heads and deeper than the torispherical heads and therefore have design pressures and expense lying between these two designs. The most common variant of semi-ellipsoidal head is the 2:1 elliptical head which has a depth equal to 1/4 of the vessel diameter. The formula for calculating the wetted area and volume for one 2:1 semi-elliptical head are presented as follows.

What are the various shapes of Dished Ends? Torispherical (Tori) The shallowest of the three main dished ends this type has less dishing and so it is cheaper to produce; Semi Ellipsoidal (Also called Semi Elliptical or Semi ) has a bit deeper dishing Theres more drawing time.

The greater depth results in the head being more difficult to form, and this makes them more expensive to manufacture.
Dished end, also called dished head or tank head , is an important pressure element for pressure vessels and boilers.The dished end is usually used at both ends of the pressure vessel and welded with the cylinder.

A spheroidal head must be a hemispheroid; only a hemispheroid is valid no segment of an spheroid will work as it will in the case of a spherical head where the head may be a spherical segment.
