Abstract

Pipe insulation assemblies ( 10 ) comprising tubular insulation ( 100 ) having a longitudinal slit ( 400 ), a jacket ( 110 ), releasable tape ( 120 ), butt sealant strips ( 600 ), and/or closing adhesives are disclosed. The jacket ( 110 ) overlays the outer surface of the tubular insulation ( 100 ). The jacket ( 110 ) has an extended lip portion ( 200 ) extending beyond the longitudinal slit ( 400 ). An adhesive ( 420 ) and an internal release liner ( 130 ) are located on the extended lip portion ( 200 ).

First claim

What is claimed is:

1. A pipe insulation assembly comprising:
tubular insulation having a longitudinal slit;
a jacket overlaying the outer surface of the tubular insulation, wherein the jacket has an extended lip portion extending beyond the longitudinal slit, wherein a side of the extended lip portion is coated with a continuous strip of a first adhesive and a first side of an internal release liner covers the first adhesive; and
a continuous strip of a second adhesive located on a second side of the internal release liner,
wherein a width of the continuous strip of the first adhesive is greater than a width of the continuous strip of the second adhesive.

2. The pipe insulation assembly of claim 1 , wherein substantially all of the second adhesive is removed from the jacket when the release liner is removed from the pipe insulation assembly.

3. A pipe insulation assembly comprising:
tubular insulation having a longitudinal slit;
a jacket overlaying the outer surface of the tubular insulation, wherein the jacket has an extended lip portion extending beyond the longitudinal slit;
a first adhesive located on the extended lip portion, wherein the first adhesive is located between the extended lip portion and the jacket;
a second adhesive located on the extended lip portion, wherein the second adhesive is located between the extended lip portion and the jacket; and
an internal release liner located between the first adhesive and the jacket, wherein the internal release liner covers the first adhesive,
wherein each of the first adhesive and the second adhesive contacts the extended lip portion, and
wherein a gap separates the first adhesive and the second adhesive.

4. A pipe insulation assembly comprising:
tubular insulation having a longitudinal slit;
a jacket overlaying the outer surface of the tubular insulation, wherein the jacket has an extended lip portion extending beyond the longitudinal slit;
an internal release liner attached to the extended lip portion and positioned so that a portion of the internal release liner reaches beyond the extended lip portion, wherein an edge of the internal release liner is adjacent to an edge of the extended lip portion forming a second lip;
a first adhesive located on a first side of the internal release liner that is attached to the extended lip portion; and
a second adhesive located on a second side of the internal release liner on the second lip.

5. The pipe insulation assembly of claim 4 , wherein a first side of the second lip is exposed when the jacket is closed.

6. The pipe insulation assembly of claim 5 , wherein the exposed first side of the second lip has dimensional markings that are visible outside the jacket when the jacket is closed.

7. The pipe insulation assembly of claim 6 , wherein the dimensional markings are made using an invisible ink.

8. The pipe insulation assembly of claim 4 , wherein dimensional markings are placed directly on the jacket and are made using an invisible ink.

9. The pipe insulation assembly of claim 1 , wherein the continuous strip of the first adhesive extends a length of the extended lip portion.

10. The pipe insulation assembly of claim 1 , wherein the continuous strip of the second adhesive extends a length of the extended lip portion.

11. The pipe insulation assembly of claim 3 , wherein a thickness of the second adhesive is greater than a thickness of the first adhesive.

12. The pipe insulation assembly of claim 3 , wherein the second adhesive is closer to an end of the extended lip portion furthest from the longitudinal slit than the first adhesive.
