Patent ID: 6843279

Claim:
A pipe insulation assembly comprising: a length of tubular insulation; the tubular insulation having a wall with an outer cylindrical surface and an inner cylindrical surface for overlaying an outer surface of a length of pipe; the wall having a length and a thickness; a longitudinally extending slit extending from the outer surface to the inner surface of the wall and for the length of the wall so that the tubular insulation can be passed over and mounted on a length of pipe; the slit having a first longitudinally extending outer edge and a second longitudinally extending outer edge; a jacket overlaying the outer cylindrical surface of the wall; the jacket being bonded to the outer cylindrical surface of the wall; the jacket having a length; the jacket having a first lateral edge portion extending along the first longitudinally extending outer edge of the slit; the jacket having a second lateral edge portion, extending along the slit in proximity to the second outer edge of the slit, that forms a longitudinally extending flap for overlapping the slit and the first lateral edge portion of the jacket; adhesive on the one of the lateral edge portions of the jacket for bonding the lateral edge portions of the jacket together with the flap overlaying and sealing the slit after the pipe insulation has been mounted on a length of pipe; a release strip overlaying the adhesive, for protecting the adhesive from degradation prior to installation, which is removed immediately prior to bonding the lateral edge portions of the jacket together to seal the jacket and the pipe insulation about a length of pipe on which the pipe insulation has been mounted; a ruler means associated with the jacket, extending for the length of the jacket, and located along one of the lateral edge portions of the jacket; and the ruler means having units of linear measurement marked thereon for measuring the pipe insulation assembly in the direction of the length of the pipe insulation assembly to facilitate the cutting of the pipe insulation assembly to a shorter length.
