PVC Pipes - Pressure Ratings

Maximum operating and required burst pressure of PVC - Polyvinyl Chloride - pipe fittings

Sponsored Links

Maximum operating and required minimum bursting pressures at 73^oF (23^oC) 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:

PVC
Nominal Pipe Size (inches)	Required Minimum Burst Pressure (psi)		Maximum Operating Pressure (psi)
Nominal Pipe Size (inches)	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

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 - 140^oF (60^oC) - the strength is derated to approximately 20% of the strength at 73^oF (23^oC).

Be aware that maximum operating pressures varies with the fittings design. Consult the manufacturing data.
