HEMISPHERICAL HEAD WITH CAP AND PETALS

Hemispherical Head Dimensional Characteristics:

With the same same design conditions with the same design pressure, design temperature and material, your calculated wall thickness under internal pressure will be approximately half of the shell thickness.

For example, if you have calculated your shell thickness under internal pressure and obtained 12 mm, your hemispherical head thickness also will be approximately 6 mm.

The inside depth of your hemispherical head will be one-half of head inside diameter (h = D/2).
