The following charts are a guide to pipe sizing. Pipe size is nominal as we use different manufacturers for all our pipe and pipe products.
Nominal size in pipes refers to a standardized designation that indicates the approximate diameter of the pipe, which does not directly correspond to its actual physical dimensions.
This includes, PVC Stormwater Pipe, PVC DWV ( drainage, waste and vent) pipe, PVC Pressure pipe.
