Carbon, Alloy and Stainless Steel Pipes - ASME/ANSI B36.10/19

Pipe sizes, inside and outside diameters, wall thickness, schedules, weight and weight of pipe filled with water - Metric Units

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:

A 4 inches (100 mm) Schedule 40 pipe has an outside diameter of 4.500 inches (114.30 mm), a wall thickness of 0.237 inches (6.02 mm), giving a bore of 4.026 inches (102.26 mm)
A 4 inches (100 mm) Schedule 80 pipe has an outside diameter of 4.500 inches ( 114.30 mm), a wall thickness of 0.337 inches (8.56 mm), giving a bore of 3.826 inches (97.18 mm).

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)
