Note: Weights are for carbon steel pipe with plain ends.

Definitions:

DN: DN (Nominal Diameter) is a dimensionless designator used in the SI (metric) system to describe pipe size.

NPS: The size of all pipe is identified by the nominal pipe size (NPS) which is a dimensionless designator used in the customary unit system (inch nominal sizes).
