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)

Which is thicker schedule 40 or 80 steel pipe?
The major difference between schedule 40 and schedule 80 pipe is the wall thickness, inside diameter, and their weight. Schedule 80 will have a greater wall thickness, a smaller inside diameter and a higher weight than Schedule 40 pipe at a given nominal pipe size.
What is the wall thickness of Schedule 80 2 inch pipe?
Schedule 80 Steel Pipe.
What thickness is schedule 40 pipe?
Schedule 40 Steel Pipe Dimensions
A more common pipe is the 4-inch schedule 40 steel pipe. This pipe's outside diameter is 4.5 with a wall thickness of 0.237 and a weight per foot of 10.79.
What does SCH 80 pipe mean?
Pipe size 1.000” Schedule 80 – The actual wall thickness is 0.179” Pipe size 2.000” Schedule 80 – The actual wall thickness is 0.218” What we can see here is that the schedule number increases the wall size, and that the wall thickness changes based on the nominal pipe size (NPS).
