How to Cut Schedule 80 PVC
General PVC pipe used in the household installation of sewer and vent lines are made of Schedule 40 PVC. The thickness of the walls of this pipe are strong enough to stand on and not distort the pipe's shape. Schedule 80 PVC pipe has the same outside diameter as Schedule 40 pipe, but the inside diameter is smaller. This makes the walls of the pipe thicker than Schedule 40 PVC pipe. Though hacksaws or handsaws can be used to cut Schedule 40 pipe, a miter saw is best used for Schedule 80 pipe to create straighter and cleaner cuts.
