Modelling

Functionality is available for the user to assign a bending machine, define fabricated pipe ends and carry out a modelling consistency check.

Pipe Routing using Bends via a Pipe Fabrication Machine

To use bends via Pipe Fabrication Machine, it is necessary to fulfil three criteria.

• The branch, pipe or zone must have the BendMacReference attribute set. The BendMacReference attribute must point to a valid Fabrication Machine World (FMWL), Fabrication Machine Group (FMGRP) or Fabrication Machine (FMBEND) which has a bending dimension (FMBDIM) matching exactly the tube outside diameter.

• The piping specification must not have a predefined radius (RADI) value for a BEND heading. AVEVA PDMS first tries to set the radius of the bend via the specification selectors. If this is not available, AVEVA PDMS then checks that the BendMacReference is available.

  The example below shows a specification containing a predefined radius (RADI) value for a BEND heading.

  

• For the bend radius to be set via a Pipe Fabrication Machine, a variable angle / variable radius Bend component (SCOM) must be defined in Paragon. The component CompType attribute must be set to VAR.

  The example below shows a SCOM element, the CompType attribute value is VAR.

  

  AVEVA PDMS then attempts to find a valid radius for bends from the BendMacReference attribute of the branch, pipe and zone sequentially in the hierarchy.

  Note:
  If no matching dimensions are found, the radius cannot be set, requiring the radius to be set by you.
