Till
Now, We have successfully designed the two components i.e. Shell and Head.

 

Design
Of Shell

Thickness
of Shell (

where,

c
= Corrosion allowance = 3 mm

?
= Joint efficiency = 0.85

 Ro = Outer shell radius = 1320 mm

 P = Design pressure = 12 kgf/cm2

 P = 1.1767 N/mm2

ID
= Internal diameter of shell = Do –

                                            = 2640 – 2(10)

                                                 
         = 2620 mm

Design
Of Torispherical Head

Stress
intensification factor (W)

 W = 1.5405

Thickness
Of Torispherical
Head )

 Where,

 Rc = Crown radius = Do

 Ri = Knuckle radius = 0.1 Do

Conclusion

In
this paper we have designed the shell and head of the pressure vessel using
ASME Section VIII division 1 as well as division 2. We have found that our
design considerations are correct and can be used for working of the vessel. We
are designing the rest of the components and that results will be included in
our next paper.
