Abstract: A method for producing heat exchanger tubes involves applying a surface coating to the tube through which a fluid medium flows and which has a number of cooling fins arranged on an outer wall. The method comprises applying a surface coating to an inner wall and the outer wall of the tube, the inner wall and the outer wall comprised of structural steel, the surface coating comprising copper, nickel, cobalt, chromium, a nickel alloy, a chromium alloy, a copper alloy, a cobalt alloy or stainless steel. The method further comprises soldering the number of cooling fins to the outer wall. The surface coating is configured to facilitate direct soldering of the number of cooling fins to the outer wall of the tube and to provide the inner wall with corrosion resistance to the fluid medium in the tube.
