Embodiments of the invention include an apparatus, an assembly, and a kit for securing a web collar (10) to a tubular member. According to one embodiment, a sleeve has a plurality of apertures (12) selectively sized and spaced to form a web collar. The web collar is positioned on a segment of casing and is secured in place with set screws. Epoxy is disposed into the apertures and cured. The cured epoxy deposits on the casing are analogous to keys welded to a shaft, extending outwardly into the apertures to secure the web collar and the centralizer.

La présente invention concerne un appareil, un assemblage et un kit destinés à fixer un collier (10) en bande de tissu sur un élément tubulaire. Selon un mode de réalisation, un manchon a une pluralité d'ouvertures (12) dont la taille et l'espacement sont choisis de manière sélective afin de former un collier en bande de tissu. Le collier en bande de tissu est positionné sur un segment d'un boîtier et est maintenu en place par des vis de pression. On place de l'époxy dans les ouvertures et on la fait sécher. Les dépôts d'époxy séchés sur le boîtier sont identiques à des ergots soudés à une tige, s'étendant vers l'extérieur dans les ouvertures afin de fixer le collier de bande de tissu et le centreur.
