2:1 ellipsoidal head weights

The weight of nozzles and internals can be estimated at 5 to 10% of the sum of the shell and head weights. The weight of a skirt can be estimated as the same weight per foot as the shell with a length given by Equation 12-8 for an ellipsoidal head and Equation 12-9 for a conical head. [Pg.340]

In years past, the ellipsoidal dished head was so much more available than the hemispherical dished head that the hemispherical head was limited primarily to small-diameter vessels. But vessel closure manufacturers have increased the nimiber of dies stocked for hemispherical head production and these are now becoming more widely used. If it were not for the cost of forming, the engineer would usually choose the hemispherical closure for the top head of a tall vertical vessel since it has the least weight and the lowest discontinuity stresses and is therefore the strongest.
