Title
(EN) METHOD FOR PRODUCING LONG, ISOLATED PIPES IN THE FORM OF A SANDWICH CONSTRUCTION
(FR) PROCEDE DE FABRICATION DE TUYAUX LONGS, ISOLES ET A STRUCTURE EN SANDWICH
Abstract
(EN)
The production of long, isolated tubes (A) comprises positioning of prefabricated pipe blanks (B) which give a reinforcing and isolating effect on the main pipe (A), keeping a distance between the pipe elements (A and B) by means of distance elements (D). An adhesive binding material is pressed into the cavity between the pipe elements from one end of the pipe to an overflow (L) positioned at the other end. Thereby end flanges (E) are holding the blanks pressed axially with a good sealing effect against the main pipe (A).
(FR)
Fabrication de tuyaux longs et isolés (A), consistant à placer des éléments de couverture de tuyaux préfabriqués (B) ayant un effet renforçant et isolant sur le conduit principal (A), en maintenant un écart entre les éléments de tuyauterie (A et B) au moyen d'écarteurs (D). Un matériau adhésif de liaison est pressé dans la cavité entre les éléments de tuyauterie depuis une extrémité du tuyau jusqu'à une gouttière (L) placée à l'autre extrémité. Ainsi des brides de fermeture (E) maintiennent les éléments de couverture en pression axiale contre le conduit principal (A) avec un bon effet d'étanchement.
