| 摘要 |
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 said casing and said inner carrier pipe, and said at least one insulation layer being directly or indirectly bonded to at least said casing or said 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. |
