Question: Pick out the wrong statement In a flanged and standard dished head, the crown radius is shell outside diameter In a flanged and shallow dished

Pick out the wrong statement
In a flanged and standard dished head, the crown radius is shell outside diameter
In a flanged and shallow dished head, the crown radius is > shell outside diameter
Flat head covers are most suitable for larger vessels operating at very high pressure
Flanged only head is a type of flat head in which gradual change in the shape at the centre results in reduced local stresses
