This pipe weight table provides pipe weight and wall thickness and other dimensions. The table does not cover tubes. Pipe dimensions (diameter) of 12 inches and smaller, have outside diameters numerically larger than the corresponding nominal sizes whereas outside diameters of tubes are the same as the nominal sizes.
Pipes are identified by the nominal pipe size. The manufacture of pipe in the nominal sizes of 1/8 inch to 12 inches, inclusive, is based on a standardized outside diameter (OD).
This OD was originally selected so that pipe with a standard OD and having a wall thickness which was typical of the period would have an inside diameter (ID) approximately equal to the nominal size.
There is now no such relation between the existing standard thickness, ODs and nominal size, these nominal sizes and standard ODs continue in use as "standard".
