You know, when we talk about schedule, the different schedules refer to the size, thickness and maximum pressure of the pipe.

PVC is pipe made of polyvinyl chloride (PVC) that conforms to a set of standards produced by ANSI.

As per article of PVCFittingsDirect  from http://hubpages.com/hub/Schedule-40-versus-Schedule-80, ”

Refer to http://www.harvel.com/pipepvc-sch40-80-dim.asp and get the table of  SCHEDULE 40 & 80 – DIMENSIONS for PVC and download other stuff about pvc here http://www.harvel.com/tech-support-downloads.asp

Normally, PVC piping is most commonly used in water systems, underground wiring, and sewer lines.

Flexible pvc pipe is other kind of PVC but strong and long-lasting and can be used in water systems, for running hookups to washing machines, or in a system for ponds and winter gardens

Flexible PVC can simplify your plumbing as it allows you to bend and curve around pumps, filters and other obstructions.
Flexible PVC retains its large inside diameter and helps to avoid the need of elbows so that water flow is not impeded and this will increase efficiency and reduce the amount the fittings required to help you get the most out of your pump.

Flexible PVC is also resistant to both UV and ozone and  can be glued into standard PVC fittings.
