Abstract
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.
Claims20
A heat shield for conduit comprising:
- a flexible, single, continuous shield body sheet consisting of a conduit-facing interior layer and an exterior layer adjacent the interior layer, the sheet having first and second ends and first and second side edges and being capable of adapting to various conduit cross-sectional shapes and sizes and directional changes of the conduit longitudinal axis and not substantially adhering to the conduit, and the exterior layer being reflective;
- and
- a means for coupling the side edges of the shield body to each other about the conduit such that a substantially longitudinal gap exists between the first side edge and the second side edge or the shield body sheet, such that the shield body is attached to the conduit without removal of the conduit from its installation.
A heat shield for conduit comprising:
- a flexible, single, continuous shield body sheet consisting of a conduit-facing interior layer and an exposed exterior layer adjacent the interior layer, the sheet having first and second ends and first and second side edges and being capable of adapting to various conduit cross-sectional shapes and sizes and directional changes of the conduit longitudinal axis and not substantially adhering to the conduit, and the exterior layer being reflective;
- and
- a plurality of conduit-mounting clamps, each clamp passing through a pair of apertures and a portion of each clamp being adjacent a portion of the interior surface of the body sheet.
A flexible, single, continuous shield body sheet consisting of a conduit-facing interior layer and an exterior layer adjacent the interior layer, the sheet having first and second ends and first and second side edges and being capable of adapting to various conduit cross-sectional shapes and sizes and directional changes of the conduit longitudinal axis and not substantially adhering to the conduit, and the exterior layer being reflective;
- and
- a plurality of conduit-mounting clamps capable of operably securing the body sheet to a conduit, where each clamp passes through a pair of apertures and a portion of the clamp is adjacent both a portion of the body sheet and the conduit.
A method of protecting a conduit from a heat source comprising the steps of:
- wrapping a portion of a conduit with a flexible, single, continuous sheet so that the sheet is placed between the conduit and a heat source, the sheet consisting of a conduit-facing interior layer and an exterior layer adjacent the interior layer, the sheet having first and second ends and first and second side edges and being capable of adapting to various conduit cross-sectional shapes and sizes and directional changes of the conduit longitudinal axis;
- and
- securing the sheet to the conduit via a plurality of clamps, where each clamp passes through a pair of apertures in the sheet and a portion of the clamp is adjacent both a portion of the body sheet and the conduit.
