A flexible metal tube and its method for manufacturing, characterized by being constituted by a tube constructed of material, length, thickness and variable diameter, which bears wrinkles or curves all parallel and circular, recesses and other projections that have the advantage that by means of a manual effort this tube can be given the desired curve, which remains rigid as long as it does not have a force opposite to that applied to form it, and can be constructed by bending a strip of sheet metal. suitable material welded or drawn tube proceeding to make the curves or wrinkles by suitable tools; it being also possible to manufacture said tubes with smooth metal sheets, subjecting them to a press operation and once the curves or wrinkles have been made, the tube is formed either by welding or any other suitable form.
