Interview Questions for Intergraph SmartPlant 3D

In SmartPlant 3D, a pipe spec and a pipe class are distinct but related concepts that govern the properties of piping systems. Think of the pipe spec as a detailed recipe, specifying every ingredient and their exact quantities, while the pipe class is a more general category, grouping similar recipes together for easier management.

A pipe spec defines the precise material, diameter, schedule (wall thickness), coating, and other specific attributes of a pipe. For example, a pipe spec might detail a 6-inch diameter, Schedule 40, carbon steel pipe with a specific epoxy coating. This level of detail ensures consistency and accuracy in material procurement and construction.

A pipe class, on the other hand, groups together pipes with similar characteristics. It simplifies the design process by allowing engineers to assign a class to a pipe run instead of specifying every attribute individually. A class might be defined as ‘Main Process Line’ and automatically assign specific material, diameter, and other properties based on predefined specifications. This promotes standardization and reduces errors. Multiple pipe specs can fall under one pipe class, offering flexibility in design.

For example, you might have a pipe class called ‘Process Water’ that encompasses several pipe specs with different diameters (say, 2”, 4”, and 6”) but all using the same material and coating.
