6) Design a tall vessel for the following conditions

Inside diameter = 2.5m, Outside diameter including insulation 2.8m, Height of the vessel = 30m,
Distance from base to bottom shell joint =1.6m, Internal pressure = 25Kg/cm2, wind load = 0.1kg/
cm2, Allowable stress of the material = 250MPa. Vessel has a platform 2m below the top and a ladder
starting from platform to the shelf bottom joint. The vessel is fully radiographed.(9)

Part C

7) Derive the equation for finding critical pressure of a thin vessel under external pressure. Hence
find the critical pressure equation for failure if the vessel is acted upon by two equal and opposite

external forces? (12)

8) a) Explain the terms SIF, allowable stress range and displacement stressrange?

b) ExpEain the steps involved in external pressure design of a thin vessel following ASME code?
Explain the various factors and plot the graphsused?(5)

c) Explain different types of flanges used in piping@PPlicati
9) a) Explain four common joining techniques used in pipes? (2)

b) Do the flexibility analysis for the following pipe configuration? A two anchor routing pipe 25cmouter
diameter has length of 10meach in x, y and z directions, Expansion of pipe is
2.5cm/100m. (10)
