Hello boys,

I have constructed a vessel with ASME in PVELite
Outside Diameter: 1500mm
Length: 3500mm
Thickness: 8mm
Temp: 150 C
Pressure: 5 barg/ FV

Thats is no problem, but know i have recieved Nozzleloads. And know the vessel has to be 12 mm! And all nozzle schedule 80S.

My question is, what are the options to reduce wallthickness.
A option is to add reinforcementplates.
A option is to weld gusset/rib on 4 sides of the nozzle. The can take the nozzleforce also. But it is very difficult the calculate.

Is there anyone who knows from his experience to solve this problem?
