1. Piping or not piping This is the question Prepared by Michal Mlynarcik 28.03.2013 CERN EDMS 1277692

2. Questions Do you need it? Is it what you think it is? Are you willing to spend resources on it? Is there an alternative? Michal Mlynarcik

3. Needs General space reservation o Create object which represents a “space reservation” for one or multiple pipes, flexible, conveyer belts, walk ways, cable trays, cables, cable bundles, wires, beam pipes etc. Piping Design o Creates object representation of single route of a pipe transporting fluid Michal Mlynarcik

4. Needs General space reservation o Cross-section shape of the space reservation may vary, is freely adjustable or exchangeable Piping Design o One circular cross-section type of a pipe with predefined standard diameters and bending rules Michal Mlynarcik

5. Needs General space reservation o Geometry representing connected objects do not have to be predefined standard parts from a catalog and the assisted part placement mechanism is not defined Piping Design o Placement of pipe parts and standard parts according to methodology. Placement of valve parts only from dedicated catalogue Michal Mlynarcik

6. Needs General space reservation o No need for multiple representations o Not to be integrated with any other specialized workbench Piping Design o Special valve parts with multiple representations o Close integration with HVAC and Equipment Arrangement workbench Michal Mlynarcik

7. Needs General space reservation o Eligible: pure mechanical assembly, electrical models, integration models, any “fluid transportation” unrelated field Piping Design o Eligible: cooling/heating networks, hydraulic networks, fluid transportation pipes Michal Mlynarcik

8. Comparison example Piping workbench Special interface Special training needed Pipe diameters predefined Only circular pipe section Routing of runs Predefined parts from catalog Build in intelligence restrictions and selection rules Multiple representation of piping parts Insulation management Part/Assembly workbench Familiar interface Regular or no training needed Any size possible Any section possible Routing of 3D splines Any parts No intelligence rules or restrictions Part also can have multiple representations Manual insulation representation Michal Mlynarcik

9. Piping Workbench restrictions  Different interface from any workbench in CATIA  Specialized training needed to work effectively  Limited to predefined diameter of pipes  Placemat of pipe part needed to receive full advantage of the workbench  The ‘route’ of the pipe will be always assembled from straight sections and elbows with diameter (not a spline or 3D curve)  Only 1 circular section type of pipe profile available  The workbench does not support constraints, the runs(pipes) are referenced to absolute 0 of the product  The pipe is not shown as hollow object (unlike real pipe)  The placing of valves (piping parts) is managed by catalogue with limited content (now only parts created by CV)  The creation of parts must strictly follow dedicated methodology and will undergo verification by CAD Support (not a simple CATPart)  Limited support after November 2013 Michal Mlynarcik

11. Alternatives Part design – Ask us for Power Copy and knowledge templates help – Supported by CAD Support Service If you insist: System Routing workbench – Routing of runs – Limited number of cross-section types – No part placement from workbench catalog  catalog disabled – Unsupported Or: Systems Space reservation – Routing of path reservation objects – Placing of item reservation objects “cubes” – No part placement from workbench catalog  catalog disabled – Unsupported There no other similar Equipment & Systems workbenches fully configured for now (HVAC and Equipment Arrangement coming in 2013) Michal Mlynarcik

12. Conclusions If you still think Piping Design workbench is suitable for YOU then: Contact CAD Support service for further information – Dedicated work methodology is developed and available – Supported by CAD Support service – Is actively used by EN\CV-DOW which helped a lot to implement it It is a highly specialized workbench, which is very useful if you use it correctly and in its scope.
