Abstract

The invention relates to a method for producing heat exchanger tubes comprising a structural steel tube (8) through which a medium flows and which is provided with a number of cooling ribs (2) arranged on an outer wall (10). According to said method, the tube (8) is provided with a surface coating (4, 5) on the inner wall (9) and on the outer wall (10), said surface coating consisting of copper, nickel, cobalt, chrome, a nickel alloy, a chrome alloy, a copper alloy, a cobalt alloy or stainless steel, for directly soldering the number of cooling ribs (2) to the outer wall (10) and for resistance of corrosion of the inner wall (9) by a fluid medium in the tube (8).
