Difference between Schedule 40 and Schedule 80 Conduit

The difference between Schedule 40 and Schedule 80 lies in the thickness of the wall of the piping. The Schedule 40 has a thinner wall than the Schedule 80 piping even when dealing with the same size pipe. Because the pipes are the same size on the outside, the difference lies in the interior. They will differ by inside diameter.
A 1" (25.4 mm) Schedule 40 pipe will have an outside diameter of 1.315" (33.4 mm) and an inside diameter of 1.029" (26.1 mm). A 1" (25.4 mm) Schedule 80 pipe will have an outside diameter of 1.315" (33.4 mm) and an inside diameter of 0.936" (23.8 mm).

They will look identical from the exterior. The reason for the difference is that thicker piping allows for larger pressure. Thinner piping and fittings however are less expensive typically.
