Cones are the most common type of head used for the manufacture of atmospheric tanks and especially stainless steel tanks. However they can be used in the manufacture of pressure vessels subject to certain criteria as listed below. (Cones for pressure vessels)
Cone angles are variable and are at the discretion of the customer.
The I.K.R for most cones is usually 25mm, 32mm, 51mm, 76mm or 102mm depending on the diameter, thickness and customer requirements. We are able to form larger knuckles on some cones, subject to the material thickness and cone angle.
