PIPE


                                                                 SIZE
Pipe is identified by nominal pipe size (NPS).

For sizes 1/8” through 12”, the actual outside diameter is larger
than the corresponding NPS. Please consult the pipe chart for
dimensional information.

For sizes 14” and larger, the outside diameter is the same as
the NPS.
