Metric Pipe Sizes Dn "Diametre Nominel" per ISO vs NPS "Nominal Pipe Size" Equivalent for DN 6 to DN 2200, NPS Schedule 5 to 30. Welded and Seamless PIpe

For instance, a 2-inch galvanized steel pipe has an inside diameter of about 2 1/8 inches and an outside diameter of about 2 5/8 inches. In plumbing pipe size is referred to as nominal pipe size - NPS, or "Nominal Pipe Size". The metric equivalent is called DN or "diametre nominel".

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.

The pipe sizes are designated by DN followed by a number to indicate standard pipe size. For example, DN50 indicates a 2″ NPS pipe; Similarly, DN80 indicates a 3″ NPS pipe. The pipe manufacturers print the DN number on the pipe surface which makes the identification easier.

Why pipes with sizes smaller than NPS 12 (DN 300) have different OD. First, we need to acknowledge that all pipe sizes should be identified as nominal pipe size (NPS). Secondly, for NPS 1/8 (DN 6) to NPS 12 (DN 300), these sizes are …
