    • A method of covering a pipeline, which can be carried out either in the factory or in the field comprises enveloping the pipeline with a covering such as a helically wound tape (20) comprising a heat recoverable layer (21), having first surrounded the pipeline with a thermal barrier layer (such as a mastic 23) that bonds to the pipeline without the application of heat. A heat activatable adhesive (22) is used to bond the heat recoverable layer (21) to the thermal barrier layer. In the most preferred embodiment the thermal barrier layer and adhesive layer are pre-applied to the heat recoverable tape, and one edge (24) of the tape is bare of thermal barrier layer to allow good bonding between adjacent overlapping turns of the tape.
    • 覆盖可在工厂或现场进行的管道的方法包括用诸如包括可热回收层(21)的螺旋缠绕带(20)的覆盖物包围管道,该热可回收层首先围绕管道 具有在不施加热的情况下粘合到管道的热障层(例如乳香23)。 使用可热活化的粘合剂(22)将热可回收层(21)结合到热障层。 在最优选的实施方案中,将热阻层和粘合剂层预先施加到可热回收的带上,并且带的一个边缘(24)裸露在热障层上,以允许在相邻的带重叠之间的良好粘结。
