AWWA C909 pipe
AWWA C909 pipe
(OP)
Hi everyone,
Is anybody familiar with PVCO pipe and the main differences between C909 and C900. Is there any Deflection issue using C909 since it has less wall thickness than C900.
Is there any website to get more information? I was looking for any evaluation study for C909 VS C900.
Thank You

The long-term stiffness of plastic pipes (slower than 1/2" on diameter per minute, load application, not reported there) is incidentally, typically just a fraction of the value obtained for plastic pipes in the short-term, parallel plate loading tests.
The significance of this is summarized by DIPRA in both these publications, ""Because pvc(o) pipe has far less stiffness than Ductile Iron, the importance of soil stiffness is greater for pvc(o). This means that with pvc(o) pipe, bedding conditions and on-the-job installation inspection are much more critical."
