What is SS Pipe Size Chart?
An SS Pipe Size Chart is a dimensional reference table that shows:
- Nominal Pipe Size (NPS)
- Outside Diameter (OD)
- Wall Thickness
- Pipe Schedule
- Pipe Weight
- Pressure Capacity
These charts help engineers, fabricators, piping contractors, and industrial buyers select the correct stainless steel pipe dimensions for specific applications.
Stainless Steel Pipe Schedule Formula
Pipe schedule indicates wall thickness and pressure capacity.
Pipe Schedule∝Wall Thickness\text{Pipe Schedule} \propto \text{Wall Thickness}Pipe Schedule∝Wall Thickness
Higher schedule numbers indicate thicker pipe walls and higher pressure handling capability.

SS Pipe Weight Formula
The stainless steel pipe weight can be calculated using the following formula:
Weight=(OD−WT)×WT×0.024661\text{Weight} = \frac{(OD – WT) \times WT \times 0.02466}{1}Weight=1(OD−WT)×WT×0.02466
Where:
- OD = Outside Diameter
- WT = Wall Thickness
