Nominal bore tables are used to provide a standardized reference for the internal diameters of PVC pipes. These tables help guide the selection of appropriate pipe sizes based on the desired flow capacity or application requirements. Nominal bore tables are available for both metric and imperial PVC pipes.
Metric PVC Pipe
For metric PVC pipes, the nominal bore tables typically provide the internal diameter in millimeters. The tables may list a range of internal diameters alongside the corresponding external diameter, wall thickness, and other relevant information. This allows users to select the appropriate metric PVC pipe based on their specific needs.
Imperial PVC Pipe
Imperial PVC pipes are often labeled with external diameters. The nominal bore tables for imperial PVC pipes convert the external diameter into the corresponding internal diameter. These tables help determine the internal diameter, wall thickness, and other key dimensions based on the external diameter of the pipe.
Nominal bore tables are essential references when working with PVC pipes as they provide a standardized system for selecting the appropriate pipe size. It is important to consult the relevant tables for the specific type of PVC pipe (metric or imperial) and the desired internal or external diameter.
