Verfahren zur schweißtechnischen Verbindung eines Wärmetauscherrohrs mit einer Kunststoffolie

摘要

A process is disclosed for joining by welding the end area of a heat exchanger pipe (2) at least sheathed with plastics to a plastic foil (5) which lines the tube plate of a heat exchanger. The heat exchanger pipe (2) is first positioned with respect to the plastic foil (5). The plastic materials which constitute the heat exchanger pipe (2) and the plastic foil (5) are then partially plasticised in the contact area (9) by inductive heating, using a metallic heat transfer medium (8) which acts as a heating element for the plastic material. When the molten plastics cool down, an irreproachable fluid-tight connection is created between the heat exchanger pipe (2) and the plastic foil (5).
