Abstract: Exhaust insulation systems and methods are described that include a base insulation layer of an insulation disposed about a section of a workpiece such as an exhaust pipe. Exhaust insulation systems and methods are described that further include a middle retaining layer at least partially surrounding the base insulation layer, and a conformal polymer outer coating forming a direct interface with the middle retaining layer.

Abstract: Clamp insulation systems and methods are disclosed. An example clamp system includes a foil cover having a top surface with a support structure, side walls and tapered end walls. The foil cover can define a pocket between the top surface, side walls and end walls. The insulation system further includes an insulation layer disposed in the pocket between the sidewalls and adjacent an inside of the top surface. The side walls can have a depth so that the pocket is capable of receiving a band of a clamp and so that the side walls are capable of being crimped about the band of the clamp.

Abstract: Exhaust insulation systems and methods are described that include multiple layers. In one example, a system includes a base insulation layer covering a portion of an exhaust pipe and a hard outer cover formed from a spirally wrapped knit tape and having a length coextensive with the length of the underlying base insulation layer. The wrapped knit tape outer cover can include successive turns of tape overlapping by 25% to 75%. The knit tape can be impregnated with a thermosetting phenolic resin prior to being wrapped about the pipe.
