Abstract (en)

[origin: WO9950610A1] The invention relates to a heat exchanger tube (1) especially for a capacitor, comprising an inner casing area (3) which is surrounded by an outer casing area (2). The casing areas (2; 3) are firmly connected to each other. One casing area (2; 3) has a highly anti-corrosive cladding material (4) and the other casing area (3; 2) comprises a base material that is less resistant to corrosion. The invention also relates to a method for the production of a heat exchanger tube (1) and a capacitor (10).
