Title (EN) INSULATING LINING USE FOR COVERING THE JUNCTION AREA OF A PIPE JOINT
(FR) GARNITURE ISOLANTE SERVANT A RECOUVRIR LA ZONE DE LIAISON D"UN JOINT POUR TUYAU
Abstract: front page image
(EN)The pipes (2, 4) formed by metal pipes (1, 3), which are provided with an anticorrosion layer (6) of a fairly large thickness, need for the junction area, an independent insulating lining (7), since this area may not be coated with the anticorrosion layer (6). The insulating lining (7) is comprised of a sleeve (8) which is fixed onto the anticorrosion layer (6) of the section (1) as well as a collar (9) to which is connected preferably a sleeve (10) bearing onto the anticorrosion layer (6) of the joint (3). The collar (9) may have the form of a bellows. It is possible to have a ring-shaped collar which may be stuck against the front surface of the joint (3).
(FR)Les canalisations (2, 4) formees de tuyaux metalliques (1, 3), qui sont pourvues d"une couche anti-corrosion (6) d"epaisseur assez grande, ont besoin, pour la zone de liaison, d"une garniture isolante independante (7), vu que cette zone ne peut etre recouverte par la couche anti-corrosion (6). La garniture isolante (7) possede un manchon (8) qui est fixe sur la couche anti-corrosion (6) du troncon (1) ainsi qu"un col (9) auquel est lie de preference un manchon (10) appuye sur la couche anti-corrosion (6) du joint (3). Le col (9) peut avoir la forme d"un soufflet. Il est possible d"avoir un col en forme d"anneau, qui peut etre colle contre la surface frontale du joint (3).
