[origin: EP1089047A2] The method comprises forming an inner wall (17) of the double wall, the inner wall extending in one direction to one extremity region, the inner wall extending in a further direction opposite the one direction to one of the opposing sides via a transition region; forming an outer wall of the double wall, the outer wall extending in the one direction to the other of the opposing sides, the outer wall extending in the further direction to a further extremity region. The transition region accommodates the further extremity region and the first extremity region deviates away from the outer wall. Independent claims are included for a tube for a heat exchanger.
