Abstract

L'invention concerne un procédé de raccordement de structures de raccordement cylindriques par raccordement d'un premier élément cylindrique (1) et d'un deuxième élément cylindrique (2) et par leur intercalation entre un connecteur interne (3) et un connecteur externe (4). Le connecteur interne (3) est placé sur la face interne de l'élément cylindrique, recouvre approximativement toute la zone dans laquelle la surface terminale (11) du premier élément cylindrique (1) et la surface terminale (21) du deuxième élément cylindrique (2) sont en contact, et présente une pluralité d'orifices (31) qui sont traversés par une pluralité de boulons (5) destinés au premier élément cylindrique, et une pluralité d'orifices (32) qui assurent la liaison des surfaces avant et arrière. Si la vis mâle (81) du boulon (8) destiné au deuxième élément cylindrique n'est pas guidée sans à-coups dans la partie taraudée (101a), le filetage extérieur (81) du boulon (8) destiné au deuxième élément cylindrique déforme la partie taraudée (101a) ou refoule la partie taraudée en résine (100) aux fins d'ajustement serré lorsque le filetage extérieur (81) du boulon (8) destiné au deuxième élément cylindrique est vissé dans la partie taraudée (101a), ce qui entraîne que la partie tête (82) du boulon (8) destiné au deuxième élément cylindrique se rapproche du connecteur interne (3). L'utilisation d'une partie taraudée en résine (100) peu coûteuse pour l'ajustement serré permet d'obtenir le couple requis entre le boulon (8) destiné au deuxième élément cylindrique et l'écrou destiné au deuxième élément cylindrique.
