The internal diameter (ID) of a 32 NB (Nominal Bore) pipe is approximately 40.0 mm. Nominal Bore is a designation used to describe the size of the pipe, but the actual internal diameter can vary slightly depending on the pipe's schedule or wall thickness. For precise applications, it's essential to refer to the relevant standards or specifications for the specific type of pipe being used.

A 250 NP pipe is a pipe that is 250 millimeters in diameter and is 10 inches long. It comes in a variety of thicknesses. NB stands for nominal bore. Sometimes this is referred to as NPS which stands for nominal pipe size. NB is a standard for pipe sizes in North America.
NB (nominal bore) is the European designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimeters. NB (nominal bore) is also frequently used interchangeably with NPS.You can refer more details herehttp://www.piping-engineering.com/nominal-pipe-size-nps-nominal-bore-nb-outside-diameter-od.html

27.2 kg/meter for 100 NB Simless pipe
The unit weight of a 60 NB (nominal bore) pipe depends on the material it is made from. For example, for a steel pipe with a nominal bore of 60 mm, the approximate unit weight can be calculated using the formula: Unit Weight = (outer diameter - thickness) x thickness x 0.024661.

Pipe is identified by NB and thickness is defined by Schedule whereas Tube is identified by OD. For more detail about piping click here : http://pipingguide.blogspot.com/
Schedule 80 means "Pipe Wall Thickness as per Sch.80 of ASME B36.10M". Pipe 80 means "3 inch NPS or 80 mm NB pipe as per ASME B36.10M". Hope that it will answer your query adequately. Regards, Bhatta

NB is nominal bore of that pipe, that doesn't mean that the pipe diameter (Inner or Outer)will be equal to the NB, but it is an digit nearest to the out side diameter of the pipe. That digit will be an easily memorable one like 25, 20, 32, 40 etc (Not like 23.25, 27.5, 41.8 etc). In standard pipes, the NB and the outside diameter will be same from 14 inches and above...
