HOW TO Reduce flow on the inlet?
(OP)
Dear friends,
I have an old Drum (1943):
Dia = 8'ID Length = 30' Test Press =195psi Op Press = 70psi
Temp = 100F Corrosion Allow = 3/16 Thickness of Head =13/16, Horizontal Cap = 12,000 Gal.
According to our calculation, I have pV2 = 9,000, we are trying to reduce less 2,700. Process Engineering recommended to change Inlet Nozzle and Piping from 10" to 12". If I have 12" Nozzle, will that still within ASME Sec. VIII Div. I? What section (UG) should I be looking at the calculation for our enlarged Inlet Openings or should we add another opening to this Drum? Thank you in advance.
Monica Lee.
