Abstract

Chacun des tuyaux comporte deux éléments tubulaires concentriques et plusieurs nervures longitudinales. Le procédé consiste en ce qu on extrude une résine au moyen d'une filière dont la section a la forme de l'élément tubulaire externe et des nervures; ensuite, on extrude une résine dans une filière dont la section correspond à l'élément interne et on réunit les semi-produits ainsi obtenus de façon qu'ils soient concentriques l'un par rapport à l'autre.
