Abstract

Tube en matière synthétique renforcé par des fibres de verre. Ce tube avec une première couche tubulaire où les fibres de verre sont orientées sensiblement dans une direction tangentielle, et une deuxième couche où les fibres de verre sont sensiblement parallèles à l'axe du tube, se caractérise par le fait que la quantité de fibres de verre dans la seconde couche tubulaire est moins de 30 % de la quantité totale de fibres de verre du tube. Utilisation de ces tubes dans les pipe-lines par exemple.Synthetic tube reinforced with glass fibers. This tube with a first tubular layer where the glass fibers are oriented substantially in a tangential direction, and a second layer where the glass fibers are substantially parallel to the axis of the tube, is characterized in that the amount of fibers of glass in the second tubular layer is less than 30% of the total amount of glass fibers in the tube. Use of these tubes in pipelines for example.
