Nominal pipe size (NPS) is a dimensionless mark of pipe size. It represents the standard pipe size when it has a specific size code without the inch symbol. For example, NPs 6 represents a pipe with an outside diameter of 168.3 mm. NPs is very loosely related to the inside diameter in...
Pipe Schedule or Pipe Schedule number of a Pipe is a dimensionless number that is related to Pipe Wall Thickness. Wall thickness of the Pipe is expressed by “Pipe Schedules or Pipe Schedule numbers“.
In the US, steel pipe is measured using a system known as Nominal Pipe Size (NPS). NPS provides the outside diameter of the pipe as well as the thickness of the pipe walls. For example, a pipe labeled NPS 14 Schedule 40 means that the pipe's outer diameter is 14 inches (35.56 cm...
PVC water pipe is described by both diameter and thickness. The diameter of PVC pipe is given in Nominal Pipe Size (NPS), the North American standard for measuring pipes. It was developed in the 1920s to give installers from different regions or countries a way to connect water systems to...
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipe. The term nominal refers to pipe in non-specific terms and identifies the inside diameter with a non-dimensional number. For example, a 2” nominal steel pipe consists of a family of steel pipe with a 2.375″ ...
