5(a)
Design a pressure vessel subjected to an internal pressure using following data. Design shouls include:
i) Shell thickness
ii) Head thickness.
iii) Flanged joint between shell and head
Data:
i) Shell and standard torispherical head:
Design pressure = 2N/mm2
Outer diameter of shell=1500 mm
Permissible stress for shell and head material=140 N/mm2
Crown Radius for head=1450mm
Corrosion allowance=1.5 mm
(ii) Flanged joint:
Gasket factor=3.75
Minimum design gasket seating stress=52.5 N/mm2
Flange material same as shell material
Permissible stree for bolt material=140 N/mm2
Desired bolt spacing = 3 times diameter of bolt.
Take W-1.77 for standard torispherical head.
Use M27 size bolts.
