Pipe Sizes and Pipe Schedule
Pipe sizes are identified using NPS (Nominal Pipe Size) or DN (Diameter Nominal), together with a wall-thickness designation such as Schedule 40, Schedule 80, 10S, or 40S. NPS and DN are nominal designators, not actual inside diameters. The actual pipe inside diameter depends on the standardized outside diameter and the selected wall thickness. For engineering … Read more
