Title (EN) HIGH PRESSURE SEALING
(FR) ÉTANCHÉITÉ SOUS HAUTE PRESSION
Abstract:
(EN) A method for manufacturing an assembly comprising a thermoplastic liner (7), a boss (1), a seal element (3) and a compressing element (4), wherein the method comprises at least the steps of: 1) Forming a boss subassembly (5) by positioning the seal element onto the boss and by securing the compressing element (4) around said seal element (3), such that the seal element (3) is compressed onto the boss (1) (S01), said compressing element (4) being at least partially made of a thermoplastic material which is chemically compatible with the thermoplastic liner; 2) Placing the boss subassembly (5) in a mold (6) for molding the thermoplastic liner (7) (S02); 3) Molding the thermoplastic liner (7) and attaching the boss subassembly (5) to the thermoplastic liner (7) during said molding (S03), wherein the compressing element (4) is at least partially welded to the thermoplastic liner (7) during said molding.
(FR) La présente invention concerne un procédé de fabrication d'un ensemble comprenant un revêtement thermoplastique (7), un bossage (1), un élément d'étanchéité (3) et un élément de compression (4), le procédé comprenant au moins les étapes consistant à : 1) former un sous-ensemble de bossage (5) en positionnant l'élément d'étanchéité sur le bossage et en positionnant l'élément de compression (4) autour dudit élément d'étanchéité (3), de sorte que l'élément d'étanchéité (3) est comprimé sur le bossage (1) (S01), ledit élément de compression (4) étant au moins partiellement constitué d'un matériau thermoplastique qui est chimiquement compatible avec le revêtement thermoplastique ; 2) placer le sous-ensemble de bossage (5) dans un moule (6) pour mouler le revêtement thermoplastique (7) (S02) ; 3) mouler le revêtement thermoplastique (7) et fixer le sous-ensemble de bossage (5) au revêtement thermoplastique (7) pendant ledit moulage (S03), l'élément de compression (4) étant au moins partiellement soudé au revêtement thermoplastique (7) pendant ledit moulage.
