Abstract

The invention relates to aluminium tubes rolled from strip metal. Known rolled tubes of this type are difficult and expensive to produce with small diameters and/or with sufficient resistance to working pressures. According to the invention, the rolled aluminium strip forms at least two layers (3, 4) in the wall of the tube, one layer (3) being offset to the thickness of the strip to join another radially adjacent layer (4), the adjacent layers (3, 4) being soldered on their entire surfaces <IMAGE>
