The Schedule classification is commonly used in North America and refers to the wall thickness of the pipe. It is denoted by numbers such as Schedule 10, Schedule 40, and Schedule 80, where the higher the number, the thicker the pipe. The Nominal Pipe Size (NPS) classification, on the other hand, is used internationally and refers to the inside diameter of the pipe. It is expressed in inches and is usually followed by a schedule number to indicate the wall thickness. For instance, NPS 6 Schedule 40 means a pipe with a 6-inch inside diameter and a wall thickness according to Schedule 40. Lastly, steel pipes can also be classified based on their wall thickness in millimeters or inches. This classification provides a more precise measurement of the pipe's thickness, usually referred to as the "wall thickness" or "wt" in specifications. The wall thickness is measured from the outside diameter to the inside diameter and can be expressed in various units of measurement, such as millimeters, inches, or gauge. In conclusion, steel pipes are classified based on their thickness using different systems such as Schedule, Nominal Pipe Size (NPS), and Wall Thickness. These classifications help ensure that the appropriate pipe is selected for specific applications, considering factors such as pressure requirements, structural integrity, and compatibility with other components of the system.
