For a given pipe size, schedule 160 would have the smallest ID (and thicker wall). Wall thickness and pressure rating goes up with increasing schedule number, causing the ID to go down with increasing schedule number.
Bevel inside of sch. 80 to match OD of sch. 40

Thicker pipe wall is required to contain higher fluid pressures. For the same fluid pressure, a thicker pipe wall is required for a larger diameter pipe than that required for a pipe of smaller diameter. A schedule of pipe sizes and wall thicknesses has been established by ASTM standards governing manufacturing of pipe. A previous description of pipe wall thicknesses as "Standard", "Extra Strong" and "Double Extra Strong" has been supplanted by a schedule of 10, 20, 30, 40 60, 80, 100, 120 and 160. Schedule 40 pipe generally compares with the previous use of "Standard". For metal pipe, Schedule 80 pipe has a thicker wall and can withstand greater pressures than a Sch 40 pipe. A point of confusion is that for PVC piping, Schedule 80 pipe has a thinner wall than Sch 40 pipe.

It is the wall thickness heavier then schedule 20 lighter then schedule 80
Pipe schedule tell you something about the wall thickness of a pipe. Higher schedule means thicker wall. The actual thickness must be read from a pipe specification sheet, as it differs from material to material. Typical pipe sch. are Sch 20, 40, 80, 160, XS, XXS.

schedule 40 is thicker than schedule 20

The psi rating for schedule 40 PVC pipe is typically around 480 psi.
The schedule of a pipe indicates its thickness. The higher the schedule number, the thicker the pipe will be. Shcedule 40 and schedule 80 seem to be the most common.

Steel pipe that is schedule 40, means that the steel pipe has a certain amount of threads on it. It also means that it can't be longer than about 10 feet.
The schedule value refers to the thickness of the wall of the pipe; the bigger the number (schedule) the bigger the wall thickness is of the pipe. The thickness is relative to the diameter of the tube/pipe an the application it is being used in.
The recommended pressure rating for 1.5 inch schedule 40 pipe is 130 psi.
Not plumbing pvc pipe, but pvc pipe made especially for wiring.
