ABSTRACT:
A method for manufacturing a multiple walled tube comprising a rolling of a plated metal strip through at least two complete revolutions to form a tube having at least a double wall which has a plated layer on the inside of the tube, said rolling being followed by a heating of the tube to cause the surface of the tube walls, which are in contact with one another, to be brazed and wherein said metal strip is plated on one side, the other side being formed by the steel of the metal strip and wherein said brazing is realized by brazing directly the plated side on the steel.
