P.V.C. AWWA C900 pipe Is supplied in three pressure pipe
classes; 100, 150, and 200. . These classes correspond to a
rated working pressure of 689, 1034, and 1397 KPa. The
rated working pressure includes a factor of safety of over
3. For normal municipal application class 150 is
specified. The characteristics of tnis class of pipe will
be used to compare to the presentiy used D.!. (Class 50)
pipe as follows:

As shown by the comparison of "K" values far P.V.C. and
Celie Pipe, the fiow characteristics are better for
P.V.Ce than for DoJ. (Values range from approximately
25% less head loss. for 150 mm P.V.C~ pipe toa
approximately equal head loss in the 300 mm size pipe).

P.V.Ce pipe 1s pressure rated at 23°C (73.40F) When fne
pipe operates at remperatures other than 23°C the

pressure capacity will vary, lee. at 15.69C (60°F)
Class 150 plpe will have a capacity of approximately
1241 KPa, at 26.79G (809F) its capacity will be 931

KPa. As the average water temperature in a municipal
system is below 23°C the actual pressure capacity of
P.vV.C. pipe would be greater fhan the manufacturer's
rated pressura. In any event, tha safety factor of
ever 3 In the rated pressure renders the C900 pipe more
than adequate in dealing with the normal maximum
municipal water system pressure of 980 KPa (145 psi).
