Process Equipment and Plant Design Generally, elliptical dished heads Resist half the pressure rating compared to hemi spherical head provided on the cylindrical shell of the same thickness and diameter All of these Are manufactured on 2:1 ratio of major to minor axis and is recommended to be used for pressure vessels operating above a pressure of 1.5 MN/m² Are approximately as strong as seamless cylindrical shell having the corresponding I.D and O.D Resist half the pressure rating compared to hemi spherical head provided on the cylindrical shell of the same thickness and diameter All of these Are manufactured on 2:1 ratio of major to minor axis and is recommended to be used for pressure vessels operating above a pressure of 1.5 MN/m² Are approximately as strong as seamless cylindrical shell having the corresponding I.D and O.D ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design A certain pressure vessel manufacturer avoids doing reinforcements calculations for openings by always providing a reinforcing pad extending upto double the diameter of the opening and of the same material and thickness as that of the shell wall. If area compensation is accepted as a code guideline, his approach leads to safe design Irrespective of the shape of the vessel Only if the opening is on spherical vessel Only if the opening is on a horizontal cylinderical vessel Only if the opening is on a vertical cylinderical vessel Irrespective of the shape of the vessel Only if the opening is on spherical vessel Only if the opening is on a horizontal cylinderical vessel Only if the opening is on a vertical cylinderical vessel ANSWER DOWNLOAD EXAMIANS APP
