Schedule 80 pipe nipple pressure rating has thicker dividers and can with stand higher psi pounds per square inch.
Schedule 80 pvc flange pressure rating.
One of the more complex questions in the plastic pipe and fittings industry is associated with the pressure rating of fit tings used in pvc schedule 40 and pvc schedule 80 systems.
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.
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.
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.
