Abstract

L'invention est relative à un mélange inhibiteur de corrosion, à un boyau d'isolement de tube ou conduit doté de ce mélange inhibiteur et à un procédé de fabrication de ce boyau d'isolement doté de ce mélange inhibiteur. Le boyau d'isolement appliqué sur le tube 1 est constitué par une enveloppe externe 2 et une enveloppe interne 3, contenant le mélange inhibiteur de corrosion, ce dernier contenant un carbonate alcalin et un borate, un silicate, un benzoate et un nitrite solubles dans l'eau. Applications : isolement de tubes et conduits et inhibiteurs de corrosion de récipients et supports et dans la construction en acier.The invention relates to a corrosion inhibitor mixture, to a pipe or conduit insulation hose provided with this inhibitor mixture and to a method of manufacturing this insulation hose provided with this inhibitor mixture. The insulation hose applied to the tube 1 consists of an outer casing 2 and an inner casing 3, containing the corrosion inhibitor mixture, the latter containing an alkali carbonate and a borate, a silicate, a benzoate and a nitrite soluble in the water. Applications: pipe and conduit insulation and corrosion inhibitors from vessels and supports and in steel construction.
