The short answer is.. A PIPE is a round tubular to distribute fluids and gases, designated by a nominal pipe size (NPS or DN) that represents a rough indication of the pipe conveyance capacity; a TUBE is a round, rectangular, squared or oval hollow section measured by outside diameter (OD) and wall thickness (WT), expressed in inches or ...
First, we need to admit that all pipe size should be identified as nominal pipe size (NPS). Second, for NPS 1/8 (DN 6) to NPS 12 (DN 300), these are based on a standard outside diameter (O.D.) This O.D. was originally selected to specify pipe dimension, but as the pipe always have an wall thickness and internal diameter (ID).
Diâmetro nominal. O diâmetro nominal de tubos (NPS, do inglês Nominal Pipe Size) é um conjunto de tamanhos de tubulação padrão utilizados em tubulações de pressão nos EUA. As mesmas dimensões de tubo são utilizados com nomes diferentes na Europa. O diâmetro nominal é especificado por dois números adimensionais: o diâmetro ...
Nominal Pipe Size ( NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures.

Pipe size is specified with two non-dimensional numbers: a Nominal Pipe Size (NPS) and a schedule (SCH). The relationship of these numbers to the actual pipe dimensions is a bit strange. The NPS is very loosely related to the inside diameter in inches, but only for NPS 1/8 to NPS 12. For NPS 14 and larger, the NPS is equal to the outside ...
"NPS xx" designates a pipe size, but not an exact inside diameter of the pipe in inches: pipes with NPS under 12, have an outside diameter which is larger than the size designator (for example a pipe NPS 4 has an actual OD of 4 ½", i.e. 114.3 mm); for pipes above 14 inches, the outside diameter and the NPS match (for example, a pipe NPS ...
Scope. 1.1 This specification covers five grades of electric-fusion (arc)-welded straight-seam or helical-seam steel pipe. Pipe of NPS 4 ( Note 1) and larger with nominal (average) wall thickness of 1.0 in. [25.4 mm] and less are covered. Listing of standardized dimensions are for reference ( Note 2 ).

Summary. Nominal Pipe Size (NPS) is a defined set of standard pipe sizes commonly used for process piping. NPS piping is defined in terms of a nominal diameter and wall thickness (defined by the pipe schedule). This article provides characteristics for …
OD is the outside diameter of the pipe and is fixed for a given size. The NPS is very loosely related to the inside diameter in inches, but only for NPS 1/8 to NPS 12. For NPS 14 and larger, the NPS is equal to the outside diameter (OD) in inches. For a given NPS, the OD stays constant and the wall thickness increases with larger SCH.
NPS to Outside Diameter Table Diameter Nominal (DN) The alternative to the imperial NPS is the metric version diameter nominal (DN), developed by the International Standards Organisation (ISO).As with the NPS system, the DN system is dimensionless, although it is based on the millimetre (mm) unit. A DN 80 pipe relates to a pipe having an outside …

In plumbing pipe size is referred to as nominal pipe size -. Outside diameters for metric and imperial standards are indicated in the table below. ISO 6708 - Pipework components - DN (Nominal Pipe Size NPS) CTS - Copper Tube Size. Sizes and dimensions of pipes and tubes, and their fittings - inside and outside diameter, weight and more.
These codes stipulate a minimum bending radius for each size pipe in addition to requirements for thinning, flattening, etc. The minimum bending radius for cold field bends is specified in ASME B31.4 (Liquid Lines) and ASME B31.8 (Gas Pipelines) A 6 ft tangent is preferred; however, some bending machines may accommodate a shorter tangent.

Nominal pipe size ( NPS) is a dimensionless designator of pipe size. It indicates standard pipe size when followed by the specific size designation number without an inch symbol. For example, NPS 6 indicates a pipe whose outside diameter is 168.3 mm. The NPS is very loosely related to the inside diameter in inches, and NPS 12 and smaller …
