I have also seen that when pipe dimensions are shown in mm dn people refer pipe sizes in nb.
Copper pipe gauge to mm.
What is pipe nb nominal bore.
Pipe dimensions this table lists the outside inside diameter wall thickness and internal area for a wide range of commercial pipe sizes.
As with steel as the gauge gets higher the thickness gets lower.
As such there is no difference between nb and nps.

Nb is also an american way to refer pipe dimensions.
These dimensions apply to carbon stainless steel pvc and seamless pipe.
Conveniently determine the diameter in inches or millimeters of wire gauges from 10 to 38 gauge.
