Pipe and tube sizes can vary depending on the industry and standard being used. The sizes are typically specified by two key dimensions: the outer diameter (OD) and the wall thickness (WT).
Nominal Pipe Size (NPS): NPS is a North American standard for pipe sizing that refers to the approximate inside diameter of the pipe. The actual OD and WT can vary depending on the schedule (Sch) of the pipe. Common NPS sizes include 1/8", 1/4", 1/2", 3/4", 1", 2", 3", 4", and so on.
Outside Diameter (OD) and Wall Thickness (WT): Tubes are often specified by their OD and WT dimensions. For example, a tube may be described as having an OD of 25 mm and a WT of 2 mm.
If you have a specific application or standard in mind, please provide more details, and I can help you with the specific pipe or tube size information you need.
