Product Description
1. Product Description
The hemispherical head is a head consisting of half a spherical shell and a straight edge (short section of a cylinder). Also known as hemispherical tank heads or hemispherical dished ends,Hemispherical heads are a popular choice for pressure vessels due to their ideal shape, which divides the pressure in the vessel equally across the head's surface. The hemispherical head with smaller diameter can be pressed as a whole, with larger diameter normally formed by petals+crown type. The hemispherical head has the minimum thickness required under the same diameter and pressure compared with other types of head,and the surface arear is smallest when the head volume is same. so Hemispherical heads has the best mechanical properties and most economical materials used. But Due to manufacturing difficulties, it is generally used for pressure vessels with higher pressure and larger diameter.
