Abstract

La présente invention concerne un dispositif d'isolation thermique pour canalisation. Le dispositif d'isolation thermique pour canalisation selon la présente invention a au moins deux corps fendus, auxquels des unités d'isolation thermique sont couplées de façon à être aptes à être séparées vis-à-vis de conduites fendues, respectivement. Chacun des au moins deux corps fendus comprend: une couche d'isolation thermique interne, une couche d'isolation thermique externe agencée dans la direction de diamètre extérieur de la couche d'isolation thermique interne, une couche d'isolation thermique intermédiaire interposée entre la couche d'isolation thermique interne et la couche d'isolation thermique externe, et une couche de protection en matière d'isolation thermique entourant la couche d'isolation thermique interne, la couche d'isolation thermique externe, et la couche d'isolation thermique intermédiaire. Chacune de la couche d'isolation thermique interne et de la couche d'isolation thermique externe est formée d'au moins une couche de matière d'isolation thermique ayant des pores fins. Un gaz inerte est injecté dans les pores fins de l'au moins une couche de matière d'isolation thermique. La couche de protection en matière d'isolation thermique est réalisée en une matière imperméable au gaz.
