Nominal Bore
Nominal Bore(NB) is the European designation equivalent to NPS is DN(diametre
nominal/nominal diameter /Durchmesser nachNorm), in which sizes are measured in
millimeters.NB is also frequently used interchangeably with NPS.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes and
fittings used for high or low pressures and temperatures. Fipe size is specifid
with two non -dimensional numbers: a nominal pipe size (NPS) for diameter based
on inches and aschedule (Sched.or Sch.) for wall thickness.
The name NPS is based on the earier lron Pipe Size (IPS) system That IPS system
was established to designate the pipe size. The sizerepresented the approximate
inside diameter of the pipe in inches An IPS 6" pipe is one whose inside
diameter is approximately 6inches Users started to call the pipe as 2inch,
4inch, 6inch pipe and so on.To begin, each pipe size was produced to have one
thicknesswhich later was termed as standard (STD) or standard weight
(STD.WT).The outside diameter of the pipe was standardized.
As the industrial requirements handling higher pressure fluids pipes were
manufactured with thicker walls, which has become knownas an extra strong (XS)
or extra heavy (XH). The higher pressure requirements increased further ,with
thicker wall pipes.Accordingly,pipes were made with double extra strong (XXS)
or double extra heavy (XXH) walls, while the standardized outside diameters
areunchanged. Note that on this website only terms XS and XxS are used.
