32" nozzle on 60" head
32" nozzle on 60" head
(OP)
What problems shall i face if i design an exchanger with a nozzle of 32" mounted on ellipsoidal head of 60"?
shell side pressure (cooling water) =10kg/cm2.
channel side pressure (CO2) =3.5 kg/cm2.
MOC= SS.
Degign temp= 65 degree.

RE: 32" nozzle on 60" head
Assuming you are under Sec VIII, Div 1:
As opening reinforcement exceeds 80% head diameter, you will need to pay attention to definition of tr in UG-37 when calculating head thickness required.
Alternatively, you can use a conical reducer, but will need to account for reinforcement, as per UG-36 (e) and (f).

The problem with sloppy work is that the supply FAR EXCEEDS the demand

With a 60/32 ratio, I suspect that either the per-tube velocity may be low (danger of laminar flow ?) or the velocity of the cooling water in the piping may be high.
I also strongly agree that conical channels to your HX is the more commonly selected solution (forget the ellipsoidal head) Conical heads are probably cheaper to fabricate also.
Is this a TEMA BEM heat exchanger ?

what other conditions that i will have to take care if i select nozzle on head?
The selection of nozzle on ellipsoidal head is due to space constrain.
Yes it is a TEMA BEM exchanger.
