Schedule 40 and Schedule 80 pipes have the main difference of sizing and diameter. A schedule 80 pipe has a thicker wall even though its exterior diameter is similar to a schedule 40 pipe. Having the same outside diameter is possible because the extra thickness of a schedule 80 PVC is inside the pipe.
Also to know is, what is Schedule 80 PVC pipe used for?
Schedule 40 PVC is usually white in color and is used for irrigation, water handling and other relatively low pressure jobs. Schedule 80 PVC is usually dark gray in color (though it can come in other colors) and is primarily used in more heavy-duty applications like industrial and institutional settings.
Likewise, what does Schedule 40 mean? The pipe schedule refers to the pipe wall thickness. The higher the schedule, the thicker is the pipe wall. For example: 2-inch nominal size steel pipe: schedule 40 has a wall thickness of 0.154 inches and schedule 80 has a wall thickness of 0.218 inches.
Keeping this in consideration, is Schedule 80 PVC stronger than Schedule 40?
Due to the thicker walls, schedule 80 PVC is not only able to handle higher PSI, it is also more resistant to bending and breaking than schedule 40 PVC. Because schedule 40 PVC and schedule 80 PVC pipe have the same outer diameter, you can use schedule 40 PVC fittings with schedule 80 PVC pipe and vice versa.
Can Schedule 40 PVC be used underground?
Schedule 40 rigid PVC conduit, elbows, that are specifically marked for underground use are suitable for use underground only by direct burial or encasement in concrete. The UL listing says both 80 and 40 can be used in both above and underground installations.

Why is it called Schedule 40 pipe?
