steel material 2400mm diameter elliptical head
A 2:1 elliptical tank head is fabricated to have a certain shape instead of a particular dish radius or knuckle radius. The dish radius is approximately 90% of the diameter and the knuckle radius is approximately 17% of the diameter. 2:1 elliptical flanged and dished heads are ASME compliant. 2:1 Elliptical Vs 2:1 Torispherical Heads - Boiler and r6155 has it correct that ASME Section VIII, Division 1, paragraph UG-32(c) does indeed allow that a permissible approximation of a 2:1 semi-elliptical head is a torispherical head with a crown radius of 0.9D and a knuckle radius of 0.17D. However, in my opinion, that is a geometric approximation only. The two heads have very different stress results, particularly at the edge of the so-called 36 Types of Screws and Screw Heads (Ultimate Chart & Guide)This head shape helps give the screw a longer thread on the same screw length because of its shorter head size. 2. Raised . Source:. Raised heads, sometimes known as oval-shaped heads, have an angle much like flat screws but have more of a dome-shaped head. Youll also need to countersink these screws to accommodate the angle.

The formula for the typical 2:1 elliptical head is listed in paragraph UG-32(d) of ASME Code Section VIII, Division 1. The general formula for all elliptical heads within Comparison Between Head Types:Hemi, SE, F&D and Flat The Four Heads. A cylindrical shell made of 0.500 inch thick Sa-516 70 material (rated to 20,000 psi at 100°F) is rolled to 48 OD. The inside diameter (ID) ends up at 47. This cylinder and the seams joining it to any attached heads are fully radiographed, and there is no corrosion allowance. Dished end manufacturing for beginnersA dishing and flanging line can form heads of any shape, be it flat, conical, standard, torispherical, semielliptical, or ellipsoidal. Material thicknesses range from 5 to 60 mm in the cold condition and up to 80 mm in the hot condition; diameters range from less than 1 meter up to more than 8 m. Pressure Vessel Tank HeadsPRESCOR manufactures seamless ASME hemispherical tank heads of many sizes from 6-5/8"OD to 60"ID. For high pressure projects, the advantage of a Hemisphere is that most ASME code calculations require less minimum thickness to hold high pressure than a 2:1 Elliptical head.
