A multilayer insulating material, comprises a single- or multilayer inner layer (1, 1') made from at least a temperature resistant and/or nonflammable material of thickness and radial dimensions selected to suit the temperature of the pipeline surface, and one or more external layers (2) made from a hose type material of lower temperature resistance than the inner layer (1, 1') is new. <??>A multilayer insulating material, especially a hose type material for pipelines carrying high temperature fluids, with a single- or multilayer inner layer (1, 1') made from at least a temperature resistant and/or nonflammable material, of thickness and radial dimensions selected to suit the temperature of the pipeline surface, and one or more external layers (2) made from a hose type material of lower temperature resistance than the inner layer (1, 1') is new. <??>An Independent claim is included for preparation of the material by bonding the internal and external layers to given an insulating laminate. |
