Process for the continuous manufacture of a soft tube-shaped structure with a multi-layer plate with a micrometric strength and a process-produced, soft, tube-shaped structure.

摘要

Process for manufacturing a soft (flexible) tubular structure including an impervious barrier (5), consisting of a multi-layer film of micrometric thickness, disposed longitudinally and in a continuous manner, all the constituents of the said soft (flexible) structure being intimately connected by a final heat treatment. Soft (flexible) tubular structures manufactured according to this process. Application to the fields of transporting all types of fluids and to protection against external corrosive (aggressive) agents. IMAGE
