Nominal bore which is designation for pipe size.
27.2 kg/meter for 100 NB Simless pipe
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 = inside diameter of the tube. OD = outside diameter of the tube.

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...

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.
