  • Method and apparatus for insulating
    Patent number: 5690147
    Abstract: A heat-insulating assembly (10) for insulating a surface of a tubular body (30) relative to the ambient air comprises a length of an annular heat-insulating body (12, 14) defining an inner cylindrical surface (17) and an outer cylindrical surface (16). A vapor-barrier layer is applied to and covers the outer cylindrical surface of the annular heat-insulating body. A through-going slit (11, 15) extends through the annular heat-insulating body (12, 14) in the entire length thereof for allowing the annular heat-insulating body (12-14) to be opened for positioning the annular heat-insulating body (10) circumferentially encircling the tubular body (30) so as to position the inner cylindrical surface (17) juxtaposed the surface of the tubular body (30).
