A hose assembly and a method of manufacturing a hose assembly are provided. The method includes providing an inner corrugated lining composed of a polymeric material, providing an outer hose assembly having a length that exceeds the target length and configured to receive the inner corrugated lining therethrough, concurrently drawing the inner lining through a reducing die and the outer hose assembly, and expanding the inner lining within the outer hose assembly to form an interference fit at least at ends of the inner lining and outer carcass. The outer hose assembly length is sufficient to compress to the target length upon the expansion of the inner lining. La présente invention se rapporte à un ensemble tuyau et à un procédé de fabrication d'un ensemble tuyau. Le procédé comprend l'utilisation d'un habillage ondulé intérieur composé d'un matériau polymère, l'utilisation d'un ensemble tuyau extérieur dont la longueur dépasse la longueur cible et conçu pour recevoir l'habillage ondulé intérieur, l'étirement simultané de l'habillage intérieur dans une matrice de réduction et l'ensemble tuyau extérieur, et l'expansion de l'habillage intérieur dans l'ensemble tuyau extérieur afin de former un ajustement avec serrage au moins aux extrémités de l'habillage intérieur et de la carcasse extérieure. La longueur de l'ensemble tuyau extérieur est suffisante pour se comprimer à la longueur cible lors de l'expansion de l'habillage intérieur.
