ABSTRACT:
The pipe insulation includes two semi-cylindrical pieces of insulating material secured by adhesive in a controlled pattern to an outer jacket or cover having a longitudinally extending overlapping flap. One strip of adhesive material with self-sealing adhesive on both sides is adhesively secured on one side to the inner side of the flap and another strip of adhesive material with self-sealing adhesive on both sides is adhesively secured on one side to the portion of the cover overlapped by the flap. The other side of each strip of adhesive material is provided with a protective paper covering during shipment and storage. When the pipe insulation is installed, the paper coverings are peeled off and the two strips of self-sealing adhesive material are pressed together.
