Nominal Pipe Size and Schedule

Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures Nominal pipe size refers to only the outside diameter (OD) of a pipe making it somewhat vague For example when we say pipe size is 2 NPS it refers to all the pipes having 2 375-inch (or 60 3 mm) as outside diameter irrespective of wall thickness and thus the inside
