A coke oven offtake piping system includes a pipe assembly for conveying coke oven gases from a coke oven to a collecting main, at least one spraying nozzle in the pipe assembly, and a discharge section with a discharge pipe having a discharge orifice. A gate member cooperates with the discharge orifice and is movable along the discharge orifice in order to present a closing surface to the extremity thereof, whereby the opening area of said discharge orifice can be varied for controlling the flow rate to the collecting main. The gate member is a spherical cap with a concave closing surface. The gate member is configured to pivot around a pivoting axis to expose the discharge orifice and to cover the discharge orifice, respectively.
