The invention relates to a float (2) for buoyant hoses comprising at least one multilayer foam body which surrounds the buoyant hose (1), whereby the foam body is composed of individual foam sheets (3, 4, 5). Inside a layer, a radial connection (6) is produced which adheringly joins two adjacent foam sheets (3, 4) to one another. In addition, the float comprises an axial connection (7) which also adheringly joins two adjacent foam sheets (3, 5) to one another from sheet to sheet. According to variant A, the radial connection (6) is exclusively produced by a layer made of a polymer material which expands when heated and occupies a large volume. According to variant B, both the radial connection (6) as well as the axial connection (7) are produced by a layer made of a non-expandable polymer material, whereby the individual layers are joined to one another for the radial and axial connection in such a way that each foam sheet (3, 4, 5) is completely single chambered.
L'invention concerne un flotteur (2) pour tuyaux flottants, comportant au moins un corps de mousse multicouches entourant le tuyau flottant (1), ce corps de mousse étant composé de différentes plaques de mousse (3, 4, 5). Une liaison radiale (6) réalisée à l'intérieur d'une couche permet de relier par adhérence deux plaques de mousse (3, 4) voisines. En outre, le flotteur comprend une liaison axiale (7) permettant également de relier par adhérence deux plaques de mousse (3, 5) adjacentes d'une couche à l'autre. Selon la variante A, la liaison radiale (6) exclusivement est formée par une couche constituée d'un matériau polymère qui présente une expansion à la chaleur et occupe un plus grand volume. Selon la variante B, la liaison radiale (6) ainsi que la liaison axiale (7) sont formées par une couche constituée d'un matériau polymère non expansible, et les couches individuelles servant à la liaison radiale et axiale sont reliées entre elles de telle manière que chaque plaque de mousse (3, 4, 5) est entièrement unicellulaire.
