However, from nps 14 and above, the nps value matches the outside diameter of the pipe. For pipe sizes with a nb of 14 inch (dn 350 mm) and above, the nominal bore is the same as the pipe outside diameter (od). The larger the table number, the thicker the surface pipe wall, the higher the pressure resistance.

In other words, an nps 14 pipe is actually.
For example, a pipe with a 12 inch nb (dn 300 mm) has an od of 12.75 inches, or 324 mm. 3/8 = nominal pipe size 18 = number of threads per inch npt = symbol for the thread series and form (i.e., national (american)standard pipe, taper) basic dimensions are given to four or five decimal places to eliminate errors when calculating gauge dimensions, they do not imply a greater degree of precision than is normally obtainable.
