SCHEDULE 40 STEEL PIPE SIZES AND DIMENSIONS

Schedule 40 steel pipes sizes, dimensions and weights are given in the following Schedule 40 steel pipe chart per ASME B36.10M-2004 "Welded and Seamless Wrought Steel Pipe" standard.

The wall thickness designations Standard, Extra-Strong, and Double Extra-Strong have been commercially used designations for many years and gradually be replaced by Schedule Number designation. “Standard” and “Schedule 40” designations are identical for up to NPS 10 (DN 250), inclusive.

Schedule Numbers are convenient designation for use in ordering pipe. The schedule number of a pipe refers to the wall thickness of the pipe: as the number increases, the wall thickness becomes thicker. Schedule 40 designation is used for medium thickness pipes.

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).
