Engineering ToolBox > Carbon, Alloy and Stainless Steel Pipes - ASME/ANSI B36.10/19
Covers the standardization of dimensions of welded and seamless wrought steel pipe for high and low temperatures and pressures.
The steel pipe data chart below can be used to find pipe sizes, diameters, wall thickness, working pressures and more The chart is based on ASME/ANSI B 36.10 Welded and Seamless Wrought Steel Pipe and ASME/ANSI B36.19 Stainless Steel Pipe.
Regardless of schedule number, pipes of a particular size all have the same outside diameter (not withstanding manufacturing tolerances). As the schedule number increases, the wall thickness increases, and the actual bore is reduced. For example:
| Diameter Nominal | Schedule | Outside Diameter - D - (mm) | Wall Thickness - t - (mm) | Inside Diameter - d - (mm) | Inside Area (cm2) | Pipe Weight (kg/m) | Water Weight (kg/m) | ||
| (inches) | (mm) | ||||||||
