It is the wall thickness heavier then schedule 20 lighter then schedule 80
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 gauge of the pipe is the wall thickness. It is easier to say Schedule 40 pipe than .180 inch wall thickness. This is the SCH 40 wall thickness for a standard 12" pipe and the actual gauge thickness will vary based on pipe size and material. The larger the Schedule number, the thicker the pipe wall thickness. Pipe Schedule is also expressed in Std., X-Stg., and XX-Stg. since some thicknesses are more common than others.
It depends on the nominal diameter of pipe, but in actual sch-40 thickness is lesser than sch-80.
The difference between schedule 40 and 80 pvc is the wall thickness and schedule 80 is thicker then schedule 40 so the higher the schedule number the thicker the wall of the pipe thus can hold more pressure.
In plumbing jargon, "schedule 40" refers to the thickness of the pipe wall. Specifically, it indicates a standard measurement for the thickness of PVC (polyvinyl chloride) pipes and fittings. Schedule 40 pipes are commonly used for residential and commercial plumbing applications due to their durability and ability to withstand high pressure.
The difference in thickness is not by the ASTM grade, but rather by the term "Schedule" - as in Schedule's 10, 40, and 80 - with schedule 10 having the lighest wall thickness, and schedule 80 having the thickest.
What does the schedule have to do with the material as schedule is the wall thickness Schedule 10, 20, 40 80 and 120 (XXH) The Schedule is telling you the wall (INTERNAL) thickness 10, 20 40, 80 and 120 XXH Whether it be steel, brass, galvanized and wrought ` About the pressure capacity, it is not the same because every material such as steel, brass, galvanized or wrought has a different strenght of materials.
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 of pipe most commonly refers to the thickness of the wall of the pipe itself. ex...schedule 40 PVC pipe has a thinner wall than sch. 80 PVC
Schedule 40 and schedule 80 have the same outside diameter (OD). The wall thickness is greater on schedule 80 than it is on schedule 40. So on schedule 80 the inside diameter (ID) gets smaller.
