What does Sch 40 mean?
Beside this, what is the difference between Sch 40 and Sch 80?
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.
People also ask, is Schedule 10 or 40 thicker?
Wall thickness will increase with the increase of pipe diameter. The scale for Schedule 10 and Schedule 80 pipe goes up to a nominal size of 36 inches. At 36 inches, Schedule 10 has a wall thickness of 0.312 inches while Schedule 80 has a wall thickness of 0.500 inches.
Pipe Schedule is the term used to describe the thickness of a pipe. The outside diameter of a pipe is the same for all Schedules in a particular nominal pipe diameter. For pipe 8-inches and under, Schedule 40 and Standard Weight pipe wall thicknesses are the same. Schedules 5, 60, 100, 120, & 140 are rarely used.
