Reasons for the high frequency of application of elliptical heads
Reasons for the high frequency of application of elliptical heads
Elliptical heads are widely used in petroleum, electronics, chemical and other industries. Investigations have found that the selection rate of elliptical heads is high. Why?Oval heads are generally used in mainland designs. The elliptical head tends to be rounded under the action of internal

Thickness distribution of elliptical head after forming
Thickness distribution of elliptical head after forming
Taking the elliptical head as an example, the appendix of GB/T 25198- -2010 "Pressure Vessel Head", the thickness reduction rate of the head may be greater than that shown in Figure 1, but the law reflected in Figure 1 has been produced in practice The proof is correct, based on this

The geometry of the standard elliptical head
The geometry of the standard elliptical head
The generatrix forming the elliptical head is smoothly connected by a 1/4 ellipse line and a short straight line parallel to the axis of rotation. Therefore, this head is composed of a half ellipsoid and a cylindrical short section of height h (called It is composed of the straight side part of the

Detailed introduction of conical head
Detailed introduction of conical head
Under the internal pressure of the main body of the cone of the tapered head, the film stress occurs at the big end. At the junction of theconeand the cylinder, due to the geometric discontinuity and the sudden curvature radius, a large lateral thrust will be generated there, which will

Stamping temperature and process of spherical head
Stamping temperature and process of spherical head
Stamping of spherical head: After the blank is out of the furnace, the operator should cooperate well, and quickly place the blank on the pressed mold to align the stamping. Long operation time and excessive temperature drop of the blank should be avoided. Stamping is generally better to take two pr

Structural stress and analysis of elliptical head
Structural stress and analysis of elliptical head
The elliptical head is a pressure part often used in pressure vessels. Under the working condition of internal pressure, the stress distribution of the elliptical head is more complicated, and the stress state is not as good as that of the spherical head. However, due to the convenience of manufactu

The difference between torispherical head and oval head
The difference between torispherical head and oval head
(1) Different shapes:Theelliptical head, also known as the elliptical head, is composed of half an elliptical sphere and a cylindrical straight side section. It has the advantages of the hemispherical head having good force and the shallow depth of the dish-shaped head. Since the curvature of the wa

The advantages of 10% dish (DHB) head
Various molds such as standard oval head (2:1 positive semi-ellipse) and 10% dish head. Please distinguish between the use of two different shapes of heads according to the design of the equipment, the conditions of use, which are beneficial to quality and cost management, especially for atmospheric

What are the functions of the elliptical head.
Anelliptical headis a head composed of two parts, a revolving elliptical sphere and a cylindrical straight section. Its role is1. At the end of the pipe, if you don’t plan to extend it now, you can weld it to the pipe with a head and use it as an end.2. Used on pressure vessels, each wi
