The standard pipe dimension tables shown above are valid for most of the pipe materials including the pipes made up of wrought iron, wrought steel, stainless steel, polyvinyl chloride (PVC) and CPVC. The NPS system is American designation of pipes and DN is the European counterpart of it.Īnother older designation called Iron Pipe Size (IPS) is equivalent to the NPS designation. The trade size of EMT refers to the maximum bundle size that can fit in the pipe. Wall Thickness for Pipe from Schedule 100 to XXSĪpart from the wall thickness, other pipe sizing parameters such as outer diameter of standard size pipes and NPS to DN conversion is also shown in the above tables. Electricians use EMT Conduit to house cables and wires throughout industrial and commercial buildings.

The chart is in compliance with ANSI B36.10M and API 5L. For example, when we say pipe size is 2 NPS, it refers to all the pipes having 2.375-inch (or 60. 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. The wall thickness unit shown in the table without bracket is in metric system i.e., millimetres ( mm), the British equivalents dimensional conversion i.e., inch is shown in bracket. Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. Wall thickness of pipes available in different standard schedules (SCH.) for NPS (Nominal Pipe Size in “inch”) as well as DN (Diameter Nominal in “mm”) are shown in below chart.
