PIPE SIZE CHART
Nominal Pipe Size (NPS)
Nominal Pipe Size is a North American set of standards used to designate pipe diameter and thickness.
Pipe size is specified with two non-dimensional numbers: a nominal pipe size (NPS) for inside diameter based on inches, and a schedule (Sched. or Sch.) for wall thickness
