Beschreibung
Zusammenfassung:	The invention relates to a method for manufacturing a thin-walled tube. The purpose of the invention is to provide a tube which has a smooth inner surface as a result of which it is suitable for use for example in guiding an air flow with little turbulence and a correspondingly small noise production. The invention now focuses on a method for manufacturing a thin-walled tube with a smooth inner surface, according to which method at least one strip of foil and a wire are simultaneously wound onto a mandrel in a helical manner and at such a pitch that at least three wound layers of the strip of foil overlap one another while enclosing the wire, whereby overlapping zones of the strip of foil are adhered to one another with substantially the whole of their surface, and on a tube obtained with such a method. The strip of foil can consist for example of aluminium and the wire of steel, in which case a tube possessing a good heat resistance and good properties with respect to fire resistance is obtained, such that it meets the requirements of a high fire risk classification.
