The present invention relates to a heat shield for pipes and tubes that is flexible, has an interior insulating layer, and has an exterior reflective layer. A shield may include a flap extending from the shield body for covering a portion of the component not already covered by the shield body. The interior layer faces the exhaust pipe, is made of woven silica, and may include a conductive coating. The exterior layer is an aluminum finish. The heat shield may be secured with stainless steel clamps or a lace and installed on an installed pipe or tube. The heat shield may be installed with an air gap between the pipe and the heat shield.

DETAILED DESCRIPTION The present invention is a heat shield for pipes and related engine components comprising an adaptable shield body sheet having an interior layer and an exterior layer and a means of securing the shield body to a pipe or tube.
In a second embodiment, the heat shield further comprises a shield flap extending from the shield body and covering a portion of the component not already covered by the shield body.
In a third embodiment, a method of insulating a pipe from heat transfer comprises the steps of placing a heat shield to a pipe and securing the heat shield with an air gap between the pipe and the heat shield.
These along with other objects and advantages of the present invention will become more readily apparent from a reading of the detailed description taken in conjunction with the drawings.
