Abstract

L'invention décrit un procédé de revêtement de conduite métallique. Le procédé comprend le réchauffement de la conduite à une température d'au moins 200 C et l'application d'une composition de résine époxy, dont l'épaisseur est d'au moins 300 microns, à la surface extérieure de la conduite réchauffée. Avant le durcissement complet de la composition de résine époxy mais, de préférence, après sa gélification, on applique un revêtement d'une polyoléfine modifiée, d'une épaisseur de 500 microns maximum. La polyoléfine modifiée est un homopolymère ou copolymère d'alpha-oléfines d'hydrocarbure comportant de 2 à 10 atomes de carbone, qui a été modifiée par greffe avec un acide ou un anhydride carboxylique organique éthyléniquement insaturé. On applique ensuite un revêtement extérieur d'une polyoléfine d'une épaisseur de 300 microns au moins, la polyoléfine étant un homopolymère ou un copolymère d'alpha-oléfines d'hydrocarbure comportant de 2 à 10 atomes de carbone et, de préférence, un homopolymère d'éthylène ou de propylène ou un copolymère d'éthylène et d'une alpha-oléfine d'hydrocarbure C3-C10. Le revêtement obtenu est résistant aux chocs et à la désagrégation cathodique. On peut utiliser le tuyau recouvert par le revêtement pour les pipelines souterrains de l'industrie pétrolière.
