Abstract:
1. A pipeline assembly ( 200 , 300 , 400 ) comprising an inner carrier pipe ( 101 ), a casing ( 102 ) and at least one closed-cell and/or solid thermal insulation material layer ( 103 , 112 , 114 ) placed in between said casing ( 102 ) and said inner carrier pipe ( 101 ), and said at least one insulation layer ( 103 , 112 , 114 ) being directly or indirectly bonded ( 220 , 222 , 321 ) to at least said casing ( 102 ) and said inner carrier pipe ( 101 ), wherein said at least one insulation layer ( 103 , 112 , 114 ) comprises at least one slit ( 201 , 204 ) substantially transversely to the longitudinal direction of the pipeline assembly ( 200 , 300 , 400 ), thereby improving the bending properties of the pipeline assembly ( 200 , 300 , 400 ) without damaging the casing, and maintaining other essential properties of the pipeline assembly ( 200 , 300 , 400 ) unchanged, the other essential properties including: thermal insulating properties, compression strength and thickness of said at least one insulation layer ( 103 , 112 , 114 ), water tightness of said casing ( 102 ), and the direct or indirect bonding between the insulation layer ( 103 , 112 , 114 ) and said casing ( 102 ) and said inner carrier pipe ( 101 ).
