OD is the outside diameter of the pipe and is fixed for a given size. The NPS is very loosely related to the inside diameter in inches, but only for NPS 1/8 to NPS 12. For NPS 14 and larger, the NPS is equal to the outside diameter (OD) in inches. For a given NPS, the OD stays constant and the wall thickness increases with larger SCH.

Outside diameter (OD) is the outside diameter of the pipe and is fixed for a given size. The pipes are always specified by outside diameter, never by inside diameter. The pipe schedule sets the pipe Wall Thickness (WT).

2020年4月11日 · In the inch system, nominal bore is abbreviated as NB; in metric systems, it is “diameter nominal” (DN), or Nominal Pipe Size (NPS) in North America. So, how does all this help us when purchasing a pipe support system?

OD：钢管的实际外径(outside diameter)，单位是MM.具有实际代表意义。 DN:钢管公称直径(nominal diameter)，又称平均外径(mean outside diameter)。 单位是mm.最初应用这个数据是因为直缝钢管的管璧相对于直径很薄，直缝钢管外径与管内径相差无几，所以取直缝钢管的外径与直 ...

The following chart gives standard pipe schedule or pipes sizes as given by ANSI / ASME B36.10M and API 5L . Data given in based on the NPS Tables given by ANSI B36.10M and includes Pipe wall thickness, outside diameter, nominal diameter.

Outside diameter (OD) is the outside diameter of the pipe and is fixed for a given size. The pipes are always specified by outside diameter, never by inside diameter. Wall Thickness

Carbon steel pipe nominal dimensions based on ASTM A106M and ASME B36.10M-2004. For other wall thicknesses and for sizes above DN 750 up to DN 2000 consult ASME B36.10M.

Explore the conversion between NB (Nominal Bore) and inches, including 80NB to inch and 25NB to inches. Use our pipe NB chart for accurate size comparisons in various applications.

2020年11月1日 · This PDF chart has NPS NB OD CF up to 1/2 “to 128” dimensions.

Nominal Bore. Nominal Bore (NB) is the European designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimeters. NB is also frequently used interchangeably with NPS. Outside Diameter. Outside diameter (OD) is the outside diameter of the pipe and is fixed for a given size.
