I want to know that which pipe and where I can use schedule 40 and where and for which pipe I can use schedule 80?
Please reply me as soon as possible
Thanks

PVC is for drainage and cold water lines. CVPC is for hot water lines.
Schedule #20 is used in lighter applications with not much pressure.
Schedule #40 is the most used in water piping and drainage.
Schedule #80 is used in applications that require a heavier stronger pipe such as a commercial contract would call for.

Pipe schedules are a measure of pipe wall thickness. These requirements exist due to specific factors within certain applicable systems. Predominately, where pressures are higher, the schedule #, or actual wall thickness, is greater; to withstand the internal pressure of whatever liquid or gas is passing through. Schedule 10 wall thickness is thinner than Schedule 40 wall thickness, open the link below for more information, I hope the will help you, good luck.
