WebExceeding the recommended maximum flow velocity, for an extended period of time, could result in excessive internal pressures in the PVC pipe system, possibly leading to a joint or pipe wall failure. For gravity sewer lines, which are not pressurized, the recommended maximum flow velocity is 10 ft./s before special considerations need to be taken for … WebMaximum Velocity. Maximum design velocities for clear effluent in concrete pipe can be very high. Unless governed by topography or other restrictions, pipe slopes should be set … WebIn the past maximum velocities of around 3.0m/s – 3.66m/s were imposed to protect the pipes from erosion. This is not generally a concern with modern pipe materials which can withstand velocities of 6.0m/s - 7.0m/s unless there is an unusual amount of sediments being transported with the water. cork and thread patterns
