A coke oven piping system (10) comprises a pipe assembly for conveying coke oven gases (14) from a coke oven to a collecting main (16); and flow control means comprising a flow orifice (22) in the pipe assembly with an associated obturating member (20), the obturating member being axially moveable between an open position at a certain distance from the flow orifice to a closed position in which it substantially obstructs the flow orifice (22). At least one throttling opening (28) is arranged so as to offer, towards the end of the closing stroke of the obturating member (20), an opening area for the gases to the collecting main (16) that depends on the axial position of the obturating member (20).
