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.
FAQ
Can you connect schedule 40 and schedule 80 2" and 4" PVC conduits together in a run?
Schedule 40 and 80 can be connected with the use of couplings. The inside diameter of the spigot of the schedule 80 conduit should be reamed to allow a smooth transition from the 40 to the 80.
What is the burn time for the non-metallic or PVC conduit?
PVC Schedule 40 and Electrical Nonmetallic Tubing (ENT) do not have a "burn times". Both of these products have been evaluated and approved for use within a two-hour firewall assembly. Some would say the product has a "two hour rating".
