    Abstract: Disclosed herein is a pipe (100) for transporting fluids such as oil or gas, said pipe comprising an inner carrier pipe (102), with an inner coating (104) on the outer surface of the inner carrier pipe (102) and a casing (108) characterised in that said inner coating and said casing are sealed by integration between the material of the inner coating and the material of the casing as a result of melting of the materials in the area which is to be integrated. Hereby a strong sealing between the casing and the inner coating is obtained, which allows for an effective encapsulation of e.g. insulation material placed in between the casing and the inner coating. The invention further relates to a method for sealing an inner coating and a casing in a pipe for transporting fluids such as oil or gas.

    Abstract: 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 moulding 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 mould. Hereafter the insulation material is injected in a liquid state into the mould 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 mould.

    Abstract: 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 according to the invention 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 e.g. be applied as a helical or circumferential cut. Hereby is obtained that the pipeline assembly can be rolled onto a reel or spool which greatly improves the installation process of the pipeline assembly. The invention further relates to a method of improving the bending properties and the use of one or more slits in the insulation material layer to increase the bending properties of such a pipeline assembly.
