All pvc schedule 80 pipe shall be manufactured from a type i grade i polyvinyl chloride pvc compound with a cell classification of 12454 per astm d1784.
Pvc schedule 80 pressure rating.
To calculate elevated temperature rating use the following formula.
To give you a thought of the size contrast 1 plan 40 pvc pipe has a 133 least divider and 450 psi while plan 80 has a 179 least divider and 630 psi.
This table defines the maximum pressure rating for the specified industry standard pipes schedule 160 schedule 40 and schedule 80.
As the temperature of the pvc increases the pressure that the pvc can withstand will decrease.
Schedule 80 pipe nipple pressure rating has thicker dividers and can with stand higher psi pounds per square inch.

It can withstand a substantial amount of exterior pressure.
The chart below will illustrate the pressure derating of pvc as temperatures increase.
For pvc fitting schedule 40 and pvc fittings schedule 80 the optimal temperature at which pvc can operate at the highest psi would be 73 degrees fahrenheit.
All compound components shall be listed with nsf and meet the requirements of nsf ansi standard 61 g as suitable for potable water and is considered lead free.
This makes it perfect for mechanical and synthetic applications.
As with burst pressure the amount of collapse pressure pvc pipe can withstand decreases as size increases.
Maximum pvc service temperature 140 f pressure de rating at elevated temperatures the pressure ratings given above are for water non shock 73 f.
The speci fi ed derating factors for pvc are suitable for pipe conveying water at.
