Abrégé

The present invention relates to a method for manufacturing an insulated pipe comprising an inner pipe, an insulation material and a casing. The manufacturing method of the present invention concerns in particular the process of molding an insulation material onto the inner pipe, comprising the step of covering the inner pipe with a closed bag with open ends and subsequently inserting the bag covered inner pipe into a mold. Hereafter the insulation material is injected in a liquid state into the mold between the inner pipe and the bag. The insulation material in a liquid state will after injection start to expand and finally solidify. During those processes, the bag is pressed towards the inner wall of the mold.

This invention relates to a pipeline assembly especially for offshore installation comprising an inner carrier pipe, a casing and at least one closed-cell and/or solid thermal insulation material layer placed in between the casing and the inner carrier pipe, and the at least one insulation layer being directly or indirectly bonded to at least the casing and the inner carrier pipe. The pipeline assembly has improved bending properties which is achieved as the insulation material layer comprises at least one slit substantially transversely to the longitudinal direction of the pipeline assembly. The slit can be applied as a helical or circumferential cut, enabling the pipeline assembly to be rolled onto a reel or spool which greatly improves the pipeline assembly installation process. Methods of improving the bending properties of such a pipeline assembly are also described.
