PROBLEM TO BE SOLVED: To provide a method and a device for controlling coke oven collecting pipe pressure by which collecting pipe pressure can meet a gain change of a pressure control process caused by a secondary side pressure change of a pressure control valve and which meet the change of the gas flow rate during coal charge to be not instable. SOLUTION: In the method for controlling the coke oven collecting pipe pressure, a PID setting value is altered so that a gain change of the pressure control process caused by a secondary side pressure change according to a secondary side pressure measurement value of the pressure control valve is canceled.
