The rapper device includes a striker and an impacting device for impacting the striker which has one end contacting the heat exchange surface in the pressure vessel. The striker includes a piston section having a piston rod projecting out of the pressure vessel via a passage opening in line with the impacting device. A piston head is slideable within a piston chamber in line with the passage opening. The piston chamber is operatively connected to a sealing gas supply. The piston head is a separate part with an aperture. The piston rod runs through the aperture, e.g., in a slideable arrangement.
