Technical FAQs
- AWWA C909 PVCO is defined by its pressure class (i.e., PC 235) where PVC is defined by its dimensional ratio (i.e., DR18).
- Finished PVCO pipe has a Hydrostatic Design Basis (HDB) of 7,100 psi, whole traditional PVC has an HDB of 4,000 psi.
- AWWA C909 PVCO Pipe has an approximately 10% larger internal diameter (ID).
- AWWA C909 PVCO Pipe is approximately 40% lighter than traditional PVC pipe products.
- AWWA C909 PVCO is 40% easier to longitudinally bend than PVC pipe.
- AWWA C909 PVCO has a maximum temperature of 130°F and PVC has a maximum temperature of 140°F.
- AWWA C909 PVCO has a smaller pipe stiffness (psi) than PVC. The pipe stiffness of PVCO pipe is still suitable for most direct burial applications.
- AWWA C909 PVCO cannot be direct tapped.
- AWWA C909 PVCO cannot be solvent welded (glued).
