Tuyaux annelés en acier inoxydable

Les tuyaux annelés en acier inoxydable DeKomTe sont des éléments de construction de grande qualité, très flexibles et étanches. Ils respectent le plus haut degré d'exigences pour cette technologie en matière de résistance à la pression, d'étanchéité au vide, de résistance à la température, de résistance à la corrosion, de flexibilité et de durée de vie.

Application

Les tuyaux annelés en acier inoxydable DeKomTe peuvent être utilisés de façon universelle pour pratiquement tous les milieux liquides et gazeux ainsi que les matériaux solides de pompage, si nécessaire avec un revêtement PTFE de protection contre les milieux particulièrement agressifs ou pour obtenir une paroi intérieure antiadhésive (tuyaux chimiques PTFE DeKomTe).

Spécifications

Ils compensent les expansions, servent de liaisons flexibles pour les installations/machines statiques avec éléments mobiles, garantissent un découplage des vibrations ou sont utilisés pour compenser les tolérances de montage inévitable. Ils sont par exemple largement utilisés en tant que tuyau d'extinction, de charge ou de remplissage.

Si vous souhaitez une protection contre les influences mécaniques, les courbures non autorisées ou l'abrasion, nous pouvons vous livrer nos tuyaux annelés en acier inoxydable avec une protection agrafée en acier inoxydable. Pour protéger des contacts ou de la manipulation dangereuse, nous équipons nos tuyaux annelés en acier inoxydable sur demande d’une isolation thermique extérieure. Les tuyaux annelés en acier inoxydable DeKomTe sont disponibles pour toutes les plages de température allant de -196 °C à + 600°C, d'un vide important à une pression allant jusqu'à 200 bar.
