The invention relates to a method for producing a metal tube (1), comprising arranging one or more metal profiles (3,5) to form at least one channel (7a-c) for conduction of a fluid, feeding the one or more metal profiles (3,5) into a clad-rolling mill, and clad- rolling at least a first (9) and a second portion (11) of the one or more metal profiles (3,5) to each other, so that the first and the second portions (9,11) are joined with each other, wherein the first and the second portions (9,11) form a seal (13) that holds the one or more metal profiles (3,5) together and seals at least part of the channel. The invention also relates to a clad-rolling mill adapted to produce a metal tube and a metal tube (1). |
