Sch 80 Pvc Pipe Pressure Rating

To calculate elevated temperature rating use the following formula.

Sch 80 pvc pipe pressure rating.

Maximum pvc service temperature 140 f pressure de rating at elevated temperatures the pressure ratings given above are for water non shock 73 f. These ratings are based on a constant pressure. Schedule 80 pvc technical information schedule 80 pvc pipe dimensions pressure ratings made in the u s a. 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.

Schedule 80 pipe nipple pressure rating has thicker dividers and can with stand higher psi pounds per square inch. Pvc pipe often gets a bad rap because it cannot handle as much pressure as various types of metal pipe. The pressure ratings shown are based on astm d2241 sdr class and astm d1785 schedule 40 80 pipes. The pressure rating is only for pipes.

However smaller sizes of pvc pipe especially schedule 80 can handle plenty of pressure for most home and business uses. 1 psi lb in 2 6 894 8 pa n m 2 1 inch 25 4 mm. Schedule 80 pvc technical information schedule 80 pvc pipe dimensions pressure ratings made in the u s a. As the temperature of the pvc increases the pressure that the pvc can withstand will decrease.

Suitable for oil free air handling to 25 psi not for distribution of compressed air or gas page 336 due to material cost variations prices subject to change. Unlike tensile strength burst pressure decreases as pipe size increases. Astm d2467 04e1 standard specification for poly vinyl chloride pvc plastic pipe fittings schedule 80. 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.

Astm d2466 06 standard specification for poly vinyl chloride pvc plastic pipe fittings schedule 40. The chart below will illustrate the pressure derating of pvc as temperatures increase. This table defines the maximum pressure rating for the specified industry standard pipes schedule 160 schedule 40 and schedule 80. Pressure de rating at elevated temperatures the pressure ratings above are for water at 73 degrees fahrenheit.

Maximum pressure ratings for pipes per. Api 5l carbon steel pipe and a 106 a 53 a333 a334. The speci fi ed derating factors for pvc are suitable for pipe conveying water at. Adjustments may be required for pressure variations.

This makes it perfect for mechanical and synthetic applications. Minimum tensile strength 60 ksi 60000 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. The maximum operating pressures derates with temperature.
