3.COMPONENT SIZE

3.1 Nominal Pipe Size

As applied in this Standard,the use of the phrase “nominal pipe size” or the designation NPS followed by a dimensionless number is for the purpose of pipe,flange,or flanged fitting end connection size identification.The number is not necessarily the same as the flange or flanged fitting inside diameter.

3.2 Reducing Fittings

Reducing fittings shall be designated by the NPS for the openings in the sequence indicated in the sketches of Figure 5.

3.3 Reducing Flanges

Reducing flanges shall be designated by the NPS for each opening.See examples in Note(4) of Table 6(Table Ⅱ-6 of Mandatory Appendix Ⅱ).
