Average diameter of the skirt = 102 + 78/ 2 = 90 inches.

Average temperature of the skirt = 87º F.

Temperature of the vessel = 325º F.

Nozzle N1:

  • OD = 10.750.

  • Wall = 0.5.

  • Length of Flange = 4.0 inches.

  • Weight of single flange = 112.

  • Element 20 to 125 is rigid. The associated diameter and wall thickness are that of the vessel. The element from 20 to 125 is stiff relative to the vessel. The element from 15 to 215 is stiff relative to the vessel.

  • The rigid element from 135 to 140 models the flange at the end of the nozzle and is rigid relative to the nozzle diameter.

  • The rigid element 225 to 230 models the flange at the end of the nozzle and is rigid relative to the nozzle diameter.

  • Local shell flexibilities are defined between 130 and 135 and 220 and 215.

  • The example considers the cantilever bending, the shear in the vessel from the skirt, and the local flexibility of the vessel shell in the vicinity of the nozzle.
