PVC Pipes - Pressure Ratings vs. Size
Maximum operating and required burst pressure of PVC - Polyvinyl Chloride - pipe fittings.
Maximum operating and required minimum bursting pressures at 73oF (23oC) for PVC pipe fittings according ASTM D1785 "Standard Specification for Poly Vinyl Chloride (PVC) Plastic Pipes Schedules 40 and 80 are indicated in the diagram and table below:
Nominal Pipe Size (inches) | Required Minimum Burst Pressure (psi) | Maximum Operating Pressure (psi) | ||
---|---|---|---|---|
Schedule 401) | Schedule 802) | Schedule 40 | Schedule 80 | |
1/2 | 1910 | 2720 | 358 | 509 |
3/4 | 1540 | 2200 | 289 | 413 |
1 | 1440 | 2020 | 270 | 378 |
1 1/4 | 1180 | 1660 | 221 | 312 |
1 1/2 | 1060 | 1510 | 198 | 282 |
2 | 890 | 1290 | 166 | 243 |
2 1/2 | 870 | 1360 | 182 | 255 |

- ASTM D2466 - 06 Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 40
- ASTM D2467-04e1 Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 80
- 1 psi (lb/in2) = 6,894.8 Pa (N/m2)
- 1 inch = 25.4 mm
Note! The maximum operating pressures derates with temperature. At the maximum operating temperature for PVC - 140oF (60oC) - the strength is derated to approximately 20% of the strength at 73oF (23oC).
Be aware that maximum operating pressures varies with the fittings design. Consult the manufacturing data.
