Subject: RE: [PipingDesign] AutoPIPE
AutoPLANT uses a public domain bi-directional neutral mapping file called
PXF (Project eXchange File) to transfer data to AutoPIPE. This can also
be
used by third party developers to link to other programs. The PXF file
contains all CAD data needed in order to create an AutoPIPE model. This
includes geometry, piping details, materials, components etc.
Importing into AutoPIPE requires the manual addition of non CAD data,
design
codes, pressures, temperatures (if not present in the AutoPLANT model),
loadings etc. Stress analysis is undertaken in AutoPIPE. Modifications
made to the model can be reimported into AutoPLANT Piping or Isometrics by
creating a PXF export file from AutoPIPE. The PXF file can also
optionally
include result data, such as displacements, support reactions, restraint
reactions, pipe force and moments, stresses for code compliance, general
stresses, and bend angular distortions. These can be post processed as
desired.
More than just centre lines are exported as AutoPLANT requires pipes, not just geometry.
If you just require centre lines to be used in a CAD program, it is
possible
to export the geometry as a DXF file.
Regards
Dave

Boo hoo.
Ah sure it was a wild shot,
On another point. Has anyone had success exporting centre lines from AutoPIPE back into AutoPLANT?
I am aware the capabilities of importing from AutoPLANT to AutoPIPE and know it has its limitations but am wondering about the reverse?

Evening Conor
Yes I have one, yes I cant understand a word of it, and no you cant have it.

Evening all,
I am trying to locate a copy of "Design of Piping Systems" by M.W. Kellogg
There was a also a 1991 edition by John Wiley and Sons Publ
I have managed to locate a copy in the nearby university library but would
like a copy for myself. I'd like allot of things but would settle for the
book for today...
Anyone biting?
Regards
Conor

and a bloody good flange they are too.

Table F was in the British Stand BS 10 before that was superseded. The Australian Standard AS 2129 still uses the nomenclature. Another standard
AS
4087 duplicates the falnges but designates them by class. They are
peculiart
to
the antipodese.
I once used the appropriate cement for the material and cement welded on stiffeners the same OD as the joint and circumferentially. Looked horrible
bit
it worked. Its amazing how chunks of the stuff can be molded right on...
almost
any shape
Gents
Have put in a 250NB (355 OD) PN20 PE slurry line; expected max pressure
16
bar. Flanged joints are stub flanges, gramophone finish, Table F steel
backing rings. Gaskets are 3mm reinforced insertion rubber. Have had a
few
blowouts at 10 bar as we are not yet up to full output. Bolts were not
being
tightened properly but I think the problem is more than that.
Need a better gasket.
Have considered:
No gasket; just tighten her up; the slurry solids might blind off any
minor
leaks.
CAF gasket. Not my favourite as the CAF is probably too hard for the
PE
grooves to get a good bite on.
Spiral wound or corrugated metal.
Metal backing ring to rubber: my favourite but where do you buy them?
Metal ring which cuts into the plastic as the joint is tightened.
Has anyone had this problem and if so how did they overcome it? No
time
for
major work to the flange faces, so the solution must be with the
gasket
itself.
In anticipation
Thanks
Steve McKenzie
