Spherical metal Seal Head for LNG Tank

Description:

Spherical end is a part of the spherical surface directly connected with the cylinder, due to the simple structure, easy to manufacture, often used as a vessel in the two independent pressure chamber of the middle head can also be used as end caps. Because there is no corner transition between the spherical surface and the cylinder, there is considerable discontinuous stress on the seal head and the cylinder near the joint. The stress distribution is not very reasonable. Therefore, in the low-pressure vessel equipment, the spherical head can be used. The biggest advantage of the spherical head is that any diameter can be customized. The boundary forces and bending moments mainly affect the stress near the joint edge, so the stress at the near-central part of the spherical cap is still dominated by the stress of the film. The stress on the cylinder farther away from the spherical cap is also dominated by the stress of the film. The connection between the spherical cap and the cylinder is affected by the boundary force, etc., and additional radial and circumferential bending stress and local film stress are induced on the basis of the original film stress.
