Have you ever been confused by the unconventional system used to delineate pipe dimensions?  Why does 10-inch NPS pipe actually measure 10.750 inches, but 14 NPS has an actual outside diameter of 14.000 inches? Is there a difference between schedule 40, STD, and 80S?  Rest assured; you are not alone!

We've created a simplified Nominal Pipe Size Chart for easy reference on your most complex projects. This chart details things such as:

- Nominal pipe size
- Outside diameter
- Schedule designations/wall thickness
- Inch and Metric dimensions in easy-to-read color-coded text
- 1/8 to 48 inch NPS
