TL;DR: The 2:1 ellipsoidal head as discussed by the authors is the most commonly used head type for high pressure applications and has a better natural geometry to withstand pressure than the other head types.
Abstract: Heads are one of the important accessories to pressure vessels and heat exchangers. The ends of the vessels are closed by means of the heads before putting them into operation. The common types in use are ellipsoidal, spherically dished (torispherical), and flat head. Ellipsoidal heads are used in vessels operating at high pressures. These also have a better natural geometry to withstand pressure. If the ratio of the major to minor axes is 2:1, they are called 2:1 ellipsoidal heads and are the most widely used.

TL;DR: In this article, a computer program to calculate the required thickness to withstand internal pressure is presented, and problems in retypes, allowable stresses, areas of reinforcement, and dimensions of reinforcement elements are charted.
Abstract: The removal of material for a nozzle opening requires compensation or reinforcement of the vessel part. Several methods--increasing the entire shell thickness, using a self-reinforcing nozzle-are suggested. A computer program to calculate the required thickness to withstand internal pressure is schematicized. Problems in retypes, allowable stresses, areas of reinforcement, and dimensions of reinforcement elements are charted. Flow charts for subroutines STGCHK and WLDSIZ, and for function ANGLE are offered.
