CA 2560732

The present invention relates to a vessel, in particular a pipe, especially an oil pipe, having a preformed film adhered onto the interior surface of the pipe, the interior surface of the preformed film reducing the deposition of at least one of asphaltenes, paraffin wax, and inorganic scale by at least 40% as compared to the interior surface of said oil pipe without said preformed film being present. In a preferred embodiment, the preformed film is adhered to the interior surface of the pipe with a primer layer with an optional barrier layer between the primer layer and the preformed film.

La présente invention concerne une cuve, et plus particulièrement une conduite, telle qu'un oléoduc, comprenant un film préformé collé sur la surface intérieure de cette conduite, la surface intérieure du film préformé réduisant d'au moins 40 % le dépôt d'asphaltènes, de paraffine et/ou de calcaire inorganique par comparaison avec une surface intérieure d'oléoduc dépourvue de ce film préformé. Dans un mode de réalisation préféré, le film préformé est collé sur la surface intérieure de la conduite au moyen d'une couche d'amorce, une couche barrière pouvant éventuellement être utilisée entre la couche d'amorce et le film préformé.
