Sch 80 Pvc Pipe Pressure Rating

Unlike tensile strength burst pressure decreases as pipe size increases.

Sch 80 pvc pipe pressure rating.

Schedule 80 pipe nipple pressure rating has thicker dividers and can with stand higher psi pounds per square inch. 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. 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. The pressure ratings shown are based on astm d2241 sdr class and astm d1785 schedule 40 80 pipes.

Adjustments may be required for pressure variations. 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. Maximum pressure ratings for pipes per. 1 psi lb in 2 6 894 8 pa n m 2 1 inch 25 4 mm.

However smaller sizes of pvc pipe especially schedule 80 can handle plenty of pressure for most home and business uses. The pressure rating is only for pipes. This table defines the maximum pressure rating for the specified industry standard pipes schedule 160 schedule 40 and schedule 80. This makes it perfect for mechanical and synthetic applications.

Pvc cpvc molded fittings do not have a pressure rating. These ratings are based on a constant pressure. 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.

Api 5l carbon steel pipe and a 106 a 53 a333 a334. Minimum tensile strength 60 ksi 60000 psi. Astm d2467 04e1 standard specification for poly vinyl chloride pvc plastic pipe fittings schedule 80. Schedule 80 pvc technical information schedule 80 pvc pipe dimensions pressure ratings made in the u s a.

The speci fi ed derating factors for pvc are suitable for pipe conveying water at. It is commonly recommended to limit these. Schedule 80 pvc technical information schedule 80 pvc pipe dimensions pressure ratings made in the u s a. Pvc pipe often gets a bad rap because it cannot handle as much pressure as various types of metal pipe.

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. Max pressure 73 x derating factor schedule 80 pipe pvc pipe operating temp f de rating factor 73 1 00 80 0 88 90 0 75 100 0 62 110 0 51 120 0 40 130 0 31 140. The chart below will illustrate the pressure derating of pvc as temperatures increase.
