Heat insulator for pipe lines |
摘要 |
A heat insulator for pipe lines for transportation of low temperature fluids which includes a plurality of longitudinally divided hollow cylindrical heat-insulating units assembled to tightly cover the outer periphery of the pipe lines, characterized in that each heat-insulating unit is composed of a heat-insulating panel element of a circular arc in cross section made of a foamed synthetic resin overlaid and integrally combined with an elastic sheet capable of absorbing stress caused by shrinkage of the heat-insulating panel element at low temperature and a thin metal plate placed on the outer surface of the elastic sheet and integrally combined therewith and that a sealing means is applied to the longitudinal and transverse joint contact surfaces of the adjacent heat-insulating units. This heat insulator can easily be fabricated, conveyed to the place where pipe lines to be protected are installed, and assembled in situ at a reduced cost and are effectively prevented from delamination of the metal plate by virtue of the elastic sheet interposed between the heat-insulating panel element and the thin metal plate.
