Understanding NB vs OD pipe measurements

When measuring steel pipe, it's important to understand the difference between Nominal Bore (NB) and Outside Diameter (OD), measured in millimetres (mm).

NB (Nominal Bore): A standardised pipe size identification. It does not represent the pipe's exact inside diameter, as the actual internal diameter may be slightly larger or smaller depending on the pipe's wall thickness and manufacturing standard.

OD (Outside Diameter): The actual measurement across the outside of the pipe, measured in millimetres, and remains consistent across all wall thicknesses of the same NB size pipe.

Nominal Bore (NB) Outside Diameter (OD)
20 mm 26.9 mm
25 mm 33.7 mm
32 mm 42.4 mm
40 mm 48.3 mm
50 mm 60.3 mm
65 mm 76.1 mm
80 mm 88.9 mm
90 mm 101.6 mm
100 mm 114.3 mm
150 mm 165.1 mm
