The 2:1 elliptical tank heads are used extensively for liquefied petroleum gas tanks, air receivers and other pressure vessels. For this type of head , the depth of tank head is one-quarter of the vessel's internal diameter. With its reduced metal thickness, elliptical tank heads offer an economic solution for medium-pressure tanks.

The elliptical dish end radius varies between the major and minor axis usually with the ratio is 2:1 . The elliptical tank head is the economical solution for pressure tanks due to the reduced metal thickness requirement. Elliptical Head - an overview ScienceDirect TopicsEXAMPLE 2 .9. Find the partial volume of a 2:1 elliptical head (R i /IDD=2 ) for which the OD is 108 inches. The level of the liquid is 35 inches and the head is spun from a 1 -inch plate. IDD = 108 - 2 ( 1 .0) 4 = 26.50 in. From Eq. 2 .95 and Figure 2 .19, you get the following:
Tolerances. Tolerances for height, scope, out-of-roundness, wall thickness, etc. are in accordance with DIN 28013 Elliptical heads . HOW TO CALCULATE THE VOLUMES OF PARTIALLY FULL 2 3 3 3.3. Semi-Elliptical Head in Horizontal Cylindrical Tank. The depth of this type of head is lower than in the hemispherical head and higher than in the torispherical, therefore, the design pressures are those found between these two designs. The most common semi-elliptical head is Korbbogenböden - JÜNGER GmbH - BödenpresswerkMachining / technical possibilities. Centre holes. Extrusions / necked-in openings. Inner/outer grinding.

The following are equations and a calculator to determine the wall thinkness and working pressure of an ellipsoidal head with t/L greater than or equal to 0.002. The require thickness of a dished semiellipsoidal head in which one-half of the "minor axis" (inside head minus the skirt) is equal to one-fourth of the inside diameter of the head skirt. Semi-Elliptical 2:1 Heads - Edmonton Exchangerto heads made from SA 516 Grade 70 material. Heads made from stainless steel, chrome moly heads , and other materials are made to order. Heads are stocked with a minimum 2 (51 mm) straight flange, however some size can be ordered with 5 (127 mm) maximum straight flange. For sizing lists, see back of this page.

Volume XLIII.IV ASME Sec I & Sec VIII Fundamentals - Part Ellipsoida head 2:1The commonly used semi-ellipsoidal head has a ratio of base radius to depth of 2:1 (shown below). The actual shape can be approximated by a spherical radius of 0.9D and a knuckle radius of 0.17D. The required thickness of 2:1 heads with pressure on the concave side is given below Example 14 - Elliptical or Ellipsoidal Heads , or, Semi Ellipsoida head 2:1 Volume and Wetted Area of Partially Filled Horizontal Ellipsoida head 2:1Summary 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.
