can't get past one moment (Batman: Arkham Knight)

karoch ... there is a moment at the factory of some kind .. I don’t remember the name ... there you free the workers of this factory .... there are five of them ... and when you already penetrate the building itself ... there a steam pipe blocks your way ... steam comes out of it ...... and you need to somehow stop the supply of steam .... so you start .... from the beginning you blow up the wall behind which this pipe goes .... on it like a hook .. .you open the window by connecting the wires and switch to the remote control mode of the Batmobile and shooting through the window with a harpoon you cling to that hook on the pipe and pull it in reverse ... and break it .... and that's all .... now you need to exit this mode and go on .... but he does not come out of it
