DESIGN AND METHOD TO ARRANGE SEAM FOR PIPE INSULATION Russian patent published in 2012 - IPC F16L59/02 F16L59/14 F16L59/16 

FIELD: construction.

SUBSTANCE: seam design for overlapping (5', 5) from an aluminium foil designed to cover and simultaneously close a cut (2', 2) in a section (1', 1) of pipe insulation from mineral wool coated with a shell (4', 4) of aluminium foil. Besides, the shell at the side facing the mineral wool is coated with a layer (8', 8) of polyethylene, by means of which it is attached to the outer layer of mineral wool of an insulating section. Besides, a double-sided adhesive tape (7', 7) is applied as overlapping onto the layer (8', 8) of polyethylene to fix the overlap (5', 5) to the foil of the shell (4', 4) arranged at the other side of the cut in the insulating section. On both sides of the double-sided adhesive tape (7) there is one and the same adhesive composition, and one of the tape sides is connected to the layer (8) of polyethylene on the inside of the overlap (5) of the shell (4) of the aluminium foil, when the polyethylene layer is in melted condition. The invention also relates to the method for arrangement of the above seam for overlapping.

EFFECT: reduced total fire load, reduced total weight.
