A method for manufacturing a curved tubular article (10) by providing a formable tubular preform (22); securing the ends of the preform to respective coupling members (24, 26) which are capable of providing elongational tension on the preform; filling the hollow interior of the preform with a heated fluid which is at a pressure sufficient to support the preform; applying mechanical pressure (46) to the exterior surface of the fluid-containing preform such that the preform is shaped into a predetermined three-dimensional serpentine configuration; replacing the heated fluid in the preform with a cooled fluid which sets the configuration of the preform; and removing the cooled fluid from the preform.
L'invention concerne un procédé de fabrication d'un article tubulaire (10) incurvé, qui consiste à fournir une préforme tubulaire (22) pouvant être mise en forme; à fixer les extrémités de ladite préforme à des éléments de couplage (24, 26) respectifs capables de produire une tension d'élongation sur cette préforme; à remplir l'intérieur creux de la préforme avec un fluide chauffé à une pression suffisante pour supporter ladite préforme; à appliquer une pression mécanique (46) sur la surface extérieure de la préforme contenant le fluide de sorte que ladite préforme est mise en forme en une configuration de serpentin tridimensionnelle; à replacer le fluide chauffé dans la préforme avec un liquide refroidi qui fixe la configuration de ladite préforme; et à retirer le fluide refroidi de la préforme.
