Walls of the inner pipe and the outer pipe form a space there between as a first volume, and the enclosure forms a space inside as a second volume, the first and second volumes being arrangeable in flow communication with each other via an opening in connection with the outer pipe. At least one blocking unit selectively blocks the at least one opening in connection with the outer pipe and the flow communication between the first volume and the second volume.
