What does DN mean on a flange?
Diameter Nominal
DN = Diameter Nominal The term Diameter Nominal refers to the internal diameter of a pipe. Together with the nominal pressure rating and the materials class, all dimensions of a piping line, e. g. flange dimensions, are defined by indicating the nominal diameter.
What is a steel flange?
A steel flange is a forged or cast ring of steel that looks like a protruded rim that helps in easy attachment of different objects and increases strength. For example, it can be used to connect different sections of pipe or connect a pipe to a pressure vessel or pump.

What is difference between NB and DN?
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….Pipe Sizes, NB, DN and NPS – Are they all the same?
| Nominal Bore (metric / NB / DN) | Nominal Bore (Imperial) | Pipe Outside Diameter (metric) |
|---|---|---|
| 20 mm | 3/4 “ | 26.9 mm |
| 25 mm | 1 “ | 33.7 mm |
| 32 mm | 1.25 “ | 42.4 mm |
| 40 mm | 1.5 “ | 48.3 mm |
Why flange is used in piping?
Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels. A cover plate can be connected to create a “blind flange”. Flanges are joined by bolting, and sealing is often completed with the use of gaskets or other methods.
What is difference between NB and OD?
NB (nominal bore) is also frequently used interchangeably with NPS. OD is the outside diameter of the pipe and is fixed for a given size. 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.
