Abstract

La présente invention a trait à des flans secondaires d'épaisseurs différentes et/ou de matériaux différents assemblés le long d'une ligne de joint ou ligne de limite. La ligne de joint peut comporter une composante directionnelle axiale et/ou une composante directionnelle radiale. Le flan est formé en une structure en U avec deux branches sensiblement parallèles et les branches peuvent être recourbées en rapprochement l'une de l'autre d'une distance qui varie selon la longueur axiale de l'organe en U. L'organe en U peut être soumis à une opération de formation sous pression pour former un organe sensiblement tubulaire. L'organe sensiblement tubulaire peut présenter une forme de section transversale non circulaire. Un gradin peut être formé au niveau de la ligne de joint grâce aux épaisseurs différentes des flans secondaires. Le gradin est placé dans une matrice de formation sous pression tourné vers l'extérieur de sorte que le gradin est réduit lors de l'opération de formation sous pression.
