Abstract

L'invention se rapporte à une conduite (11) en acier pourvue d'une gaine formée solidairement et à son mode de formation. La gaine est conçue pour un usage dans des milieux corrosifs et abrasifs et est constituée d'un polymère relativement épais (16) qui est collé à chaud à la conduite (11) en métal. On applique une couche de polymère/adhésif intermédiaire (80) à la conduite (11) en métal pour faciliter la liaison thermique/chimique. On applique la couche intermédiaire (80) à la tôle (11) de préférence lors d'un traitement préalable avant le profilage des nervures (12) dans la tôle. On applique la gaine de protection en polyéthylène (16) une fois que le tuyau a été profilé pour lui conférer une surface lisse, hydrauliquement efficace, pouvant résister à l'action corrosive de l'acide sulfurique et des autres acides de même type que l'on trouve dans les installations sanitaires, ainsi qu'à l'abrasion provoquée par l'écoulement de débris transportés par les eaux tels que la terre et le gravier comme on en trouve dans les installations de drainage.
