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.

Lewiski and Magnucki (2010) considered a dished head of a pressure vessel subject to internal uniform pressure.Stress Analysis of Thin-Walled Pressure VesselsJan 15, 2015ness of the walls [3][2]. As a general rule, pressure vessels are considered to be thin -walled when the ratio of radius r to wall thickness is greater than 10 t . Pressure vessels fail when the stress state in the wall exceeds [4] some failure criterion [5][6] . Therefore pressure vessels are designed to have a thickness proportional to the ra-Simple Thin Pressure Vessels Engineering LibraryThin pressure vessels are those for which the ratio of the least radius of curvature of the wall to its thickness is greater than ten. These thin pressure vessels are further subdivided into simple ones which are discussed in Section 8.3.1 and stiffened ones which are discussed in Section 8.3.2. Thick pressure vessels are discussed in Section 8.4.

The program calculates the design pressure for the vessel only when the thickness is known. As such calculations are normally done only for an existing vessel, the head attached to that vessel would normally withstand the pressure calculated for the latter.

Elliptical Head

Elliptical HeadChina Elliptical head factory and manufacturers SidaThe circumferential tension (compression) stress of the cylinder is reduced. Therefore, it is better to use an elliptical head, because there is no convex deformation when the elliptical head is connected to the cylinder, it has a continuous bending radius and does not generate stress; so it can be used in higher pressure vessels.
