Bjorklund6, 7 investigated failure rates of PVC in water distribution systems in Sweden. The better performance of pipes made after 1973 was attributed to significant improvements in pipe quality as a result of using higher K-value resin and achieving
The utility of u-PVC pressure pipes for the conveyance and distribution of potable water has been proven beyond doubt for the past 30 years. Its versatility demonstrates a key advanPE100 ISO9001e – adaptability to changing times and environments.
At a flow of 7 feet per second, which is the maximum recommended safe flow for PVC pipe, the maximum possible pressure increase due to velocity change would be a whopping 1/3 PSI. So in theory, using a smaller pipe would eliminate that 1/3 PSI pressure gain.
A pressure pipe is obviously a pipe flowing under pressure as in water pipes. A gravity pipe is a pipe that flows without pressure as in sanitary drainage, and storm water pipes. If a gravity pipe is flowing full, we use the same formula as a pressure pipe, using the ''hydraulic'' grade for the pressure pipe, and the actual grade for the gravity pipe.
