A METHOD FOR PRODUCING A METAL TUBE BY CLAD ROLLING ONE MORE PROFILES TO FORM AT LEAST ONE CHANNEL, A CLAD ROLLING MILL FOR JOINING ONE OR MORE PROFILES, A CLAD ROLLED METAL TUBE.
A METHOD FOR PRODUCING A METAL TUBE BY CLAD ROLLING ONE MORE PROFILES TO FORM AT LEAST ONE CHANNEL, A CLAD ROLLING MILL FOR JOINING ONE OR MORE PROFILES, A CLAD ROLLED METAL TUBE.
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 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 (7a-c). The invention also relates to a clad-rolling mill adapted to produce a metal tube (1 ) and a metal tube (1).
