Pressure Vessel Head

Short Description:

The elliptical head is composed of a half ellipsoid and a short cylinder. The function of the straight section is to avoid a sudden change in the radius of curvature at the joint weld of the head and the cylinder to improve the stress of the weld. Since the ellipsoidal part of the head is smooth and continuous in curvature change, the stress distribution is relatively uniform, and the elliptical head is much less deep than the hemisphere, which is easy to be stamped and formed. It is one of t...

    The elliptical head is composed of a half ellipsoid and a short cylinder. The function of the straight section is to avoid a sudden change in the radius of curvature at the joint weld of the head and the cylinder to improve the stress of the weld. Since the ellipsoidal part of the head is smooth and continuous in curvature change, the stress distribution is relatively uniform, and the elliptical head is much less deep than the hemisphere, which is easy to be stamped and formed. It is one of the most widely used heads in medium and low pressure containers. .
