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.

What is a pipe schedule?

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.

What is mean by schedule 80 for Pipes?

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.

What is the difference between 40 and 40S pipe schedule?

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.
