| условный диаметр (Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. Pipe size is specified with two non-dimensional numbers: a nominal pipe size (NPS) based on inches, and a schedule (Sched. or Sch.). NPS is often incorrectly called National Pipe Size, due to confusion with national pipe thread (NPT). The European designation equivalent to NPS is DN (diametre nominal/nominal diameter), in which sizes are measured in millimetres. The term NB (nominal bore) is also frequently used interchangeably with NPS. wiki Alexander Demidov); Ду (akhmed) | |||
