There are three main categories for classifying steel pipes based on their thickness: Schedule, Nominal Pipe Size (NPS), and Wall Thickness. In North America, the Schedule classification is commonly used and refers to the pipe's wall thickness. It is indicated by numbers like Schedule 10, Schedule 40, and Schedule 80, where a higher number means a thicker pipe.
On the other hand, the Nominal Pipe Size (NPS) classification is used internationally and refers to the pipe's inside diameter. It is expressed in inches and is usually followed by a schedule number to indicate the wall thickness. For example, NPS 6 Schedule 40 means a pipe with a 6-inch inside diameter and a wall thickness according to Schedule 40.
Additionally, steel pipes can be classified based on their wall thickness in millimeters or inches. This classification provides a more precise measurement of the pipe's thickness and is commonly 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 like millimeters, inches, or gauge.
In summary, steel pipes are classified based on their thickness using different systems such as Schedule, Nominal Pipe Size (NPS), and Wall Thickness. These classifications ensure the selection of the appropriate pipe for specific applications, taking into account factors such as pressure requirements, structural integrity, and compatibility with other system components.

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.
Steel pipes are classified based on their thickness into three categories: standard, extra strong, and double extra strong.
