Verifying thickness of a pressure vessel
Verifying thickness of a pressure vessel
(OP)
Hi all!
I'm in a big hurry trying to verify if a vessel could be adequated for a new service. The problem is as follows:
1.- The vessel is 36 in OD 10 feet high, pipe A-106 Gr. B.
2.-Bottom ellipsoidal 2:1 cap A-516 Gr. 70.
3.- Top Flange B.16 600#.
and should be used in the following conditions:
Fluid Natural Gas.
Corrosion allowable 1/16".
T= 30ÂșC.
Poperating = 1024 psig.
for my preliminary estimations, using ASME SEC VIII D1, it could not be adequated for the service. The problem is that this is the only vessel available. S (A-106) =17.1 ksi and S (A-516) 20 ksi.
Is there any code/criteria that can help to support/justify that vessel for de described service?
or
should I not use it?
Thanks in advance

RE: Verifying thickness of a pressure vessel
thickness for pipe = 1 inch.
thickness for cup = 1 inch.
It is possible justify this vessel by using maximum stress values other than recommended by standards?
thanks
RE: Verifying thickness of a pressure vessel
Will it check out without the corrosion allowance?
RE: Verifying thickness of a pressure vessel
MAWP = 1126 psi (110% Pop)
t=PR/(SE+0.4P) (Based on external radius)
t= 1.155 inch, which is greater than actual w/o using corrosion allowance, that's the problem.
For ellipsoidal cup: t=1.07 inch, which is closer but w/o corrosion...
If approved it's going to be installed at the discharge of a compression station. In fact it is a coalescer filter...
