2:1 Semi-Ellipsoidal heads.
2:1 Semi-Ellipsoidal heads are deeper than a torispherical head and therefore stronger and able to resist greater pressures. These heads are more difficult to form owning to the greater depth required. As a result these are more expensive to form than a torispherical head, but may allow a reduction in material thickness as the strength is greater.
Torispherical heads are the most common type of head used for the manufacture of pressure vessels and usually the most economical to form.
Hemispherical heads allow more pressure than any other head. However, the hemispherical head is the most expensive to form, as they consists of a number of petals or gores. The number of which depends on the size of the head and the thickness of the plate to be used. The depth of the head is half of the diameter
Shallow heads are the most common type of head used for the manufacture of atmospheric tanks and vessels and usually used on horizontal tanks. These heads are not suitable for pressure vessels and not recommended for tanks or vessels with external loads, i.e. agitators, nozzles with high loads.
Flat head is a flat end with a knuckled outer edge.
It is typically used as bases on vertical atmospheric tanks and lids for smaller tanks.
Dished head is only heads are generally used for atmospheric tanks and vessels and for bulk heads or baffles inside horizontal tanks or tankers.
