Understanding Stainless Steel Pipe Dimensions

Stainless steel pipes are available in a wide range of dimensions, tailored to suit various applications across industries. Understanding these dimensions is crucial for selecting the right type of pipe for specific needs. The dimensions of stainless steel pipes are generally described by their nominal pipe size (NPS), outer diameter (OD), wall thickness (WT), and schedule (SCH).

Key Dimensions of Stainless Steel Pipes

1. Nominal Pipe Size (NPS)
   • NPS is a standardized way of referring to the size of a pipe. It represents the approximate inside diameter (ID) of the pipe in inches. For instance, an NPS 2 pipe has an approximate inside diameter of 2 inches.
2. Outer Diameter (OD)
   • The OD of a pipe is the distance across the outside of the pipe. This measurement is crucial because it determines the pipe’s fitting and installation requirements. The OD remains constant regardless of the pipe’s schedule.
3. Wall Thickness (WT)
   • Wall thickness refers to the thickness of the pipe’s wall, which influences the pipe’s strength and pressure rating. Thicker walls can handle higher pressures. Wall thickness is usually specified in millimeters or inches.
4. Pipe Schedule (SCH)
   • The schedule of a pipe indicates the wall thickness. As the schedule number increases, the wall thickness increases, allowing the pipe to withstand higher pressures. Common schedules include SCH 5, SCH 10, SCH 40, SCH 80, and SCH 160.

Common Dimensions and Standards
