Sch 80 pvc pipe pressure rating.

Pressure de rating at elevated temperatures the pressure ratings above are for water at 73 degrees fahrenheit. Pvc cpvc molded fittings do not have a pressure rating. Adjustments may be required for pressure variations. This makes it perfect for mechanical and synthetic applications.

These ratings are based on a constant pressure. The pressure ratings shown are based on astm d2241 sdr class and astm d1785 schedule 40 80 pipes. The chart below will illustrate the pressure derating of pvc as temperatures increase. Maximum pvc service temperature 140 f pressure de rating at elevated temperatures the pressure ratings given above are for water non shock 73 f.

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. Schedule 80 pipe nipple pressure rating has thicker dividers and can with stand higher psi pounds per square inch. Minimum tensile strength 60 ksi 60000 psi.

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. As the temperature of the pvc increases the pressure that the pvc can withstand will decrease. To calculate elevated temperature rating use the following formula.

The pressure rating is only for pipes.
