large diameter nozzles in heads
large diameter nozzles in heads
(OP)
My problem /question, vessel inside diameter 84", 2:1 dished head, outlet nozzle required in top head which has an i/d of 48", with reniforcment nozzle o/d 68". Alougth acceptable to code & calc's the head is left with knuckle area only.
Alternative hemi head or cone with 30 deg angle to avoid knuckle radius.
My question is using cone on the reinforcment of the 48"Nozzle ?
The 84" vessel wall thickness is 90 mm and at nozzle end 48"I/D for pressure 50 mm. Do I need to consider any further reinforcment. The cone would be manufactured from 90 plate.

RE: large diameter nozzles in heads
Why you don't want the hemiellipsoidal solution? In my opinion this is better (provided all the criteria for pressure dimensioning are met, of course): it is also shorter, but possibly this is unimportant in your situation.
