DESIGN AND SELECTION OF PLASTIC PRESSURE PIPE Puhui Pipe manufacturer in China
Stopping a flow that had a velocity of 8 fps will cause a pressure surge of 90 psi in an 12” DR17 HDPE pipe. The anticipated pressure surge is larger than the surge allowance of 62.5 psi. The working pressure of the HDPE pipe should be limited to 97.5 psi (187.5 psi - 90 psi =97.5 psi).
