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.

Nominal bore which is designation for pipe size.
NB = inside diameter of the tube. OD = outside diameter of the tube.

the inner diameter of the pipe Nominal bore (NB) is 40 mm
27.2 kg/meter for 100 NB Simless pipe
14" and above
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...

what is difference between NB & OD in pipe size
what is weight of 60 dia ms pipe
NB = Nominal Bore. Bore is the internal diameter of the pipe. The 50 is referring to 50mm (5cm). So it boils down to a pipe with an internal diameter of 50mm.
