Pipe bore is the actual minimum inside diameter of a pipe, which is not necessarily the nominal pipe size.
Nominal bore which is designation for pipe size.
bore of the pipe is the internal diameter of pipe but the nominal diameter of pipe is the dia of a circle which is draw through a point which is situates at exactly half of the thickness of pipe or we can say that (outer dia of pipe- thickness of pipe )=nominal bore of pipe.
In Full bore ball valve, The bore dia will be same as internal dia of the pipe.In reduced bore, the bore dia is reduced than the ID of pipe.
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.
The nominal bore of a pipe is its internal diameter. The nominal bore determines how much volume you have in the pipe to transport your particular substance.

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.
In Full bore ball valve, The bore dia will be same as internal dia of the pipe.In reduced bore, the bore dia is reduced than the ID of pipe.
the inner diameter of the pipe Nominal bore (NB) is 40 mm
Pipe with a Nominal Bore of 4 inch (100mm) Outside Diameter 114.3mm
The salt water rate that is flowing from a well bore, that has 600psi and 22 choke, through a 2inch pipe at the surface will only have as much force behind it as the pipe can hold. This will depend on what the pipe is made of, and what weight it is capable of.
In the context of a flange, "bore" refers to the internal diameter of the flange's opening. This measurement is crucial as it determines the size of the pipe or fitting that can be connected to the flange. Proper alignment and sealing depend on the bore size being compatible with the associated piping system. Flanges with different bore sizes are used to match various pipe diameters and flow requirements.
The outside diameter (OD) of a 40-inch nominal bore black steel pipe is typically 40 inches, as the nominal size refers to the approximate internal diameter of the pipe. However, the actual OD for standard pipe sizes can vary; for a 40-inch nominal bore, the standard OD is approximately 42.16 inches according to the American National Standards Institute (ANSI) specifications. This discrepancy is due to the wall thickness of the pipe, which is accounted for in the nominal size.
