RE: 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?

   Regards

   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

   Table F was in the British Stand BS 10 before that was superseded.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.

   BAcking rings from table F ... are these AWWA.. I'm not familiar with    that
   table.

   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
