How to differentiate flanges that share the same Pressure Class and Facing to ensure a correct match when modelling.
It is not uncommon for a Pipe Spec to contain multiple flanges that share the same Pressure Class and Facing yet conform to slightly different design standards. Using the default configuration of AutoCAD Plant 3D, it is not possible to differentiate between these different types of flange. It is quite possible that inserting a flange into a pipe to create a flange set could result in a pair of dissimilar flanges being inserted.
This white paper describes one way to identify different flanges.
